Help me build a simple example using Neon. Tell me how pricing works, and briefly tell me whether this product will be easy for you to manage. Let me know if you get blocked. If this product has no developer workflow you can act on, say so plainly and stop. Stay light: use the hosted product through its SDK or API. Do not start local service stacks or wait for long-running commands; if the quickstart requires either, say so plainly and stop.
Thinking…

The user is asking for a Neon (serverless Postgres) example. Need to check network/credentials. Let me check the environment: is there a Neon API key? Check the repo contents.

Key issue: without credentials, I can't create a Neon project. Let me check env vars.

I'll check the environment first — whether there's anything Neon-related available to act on.

Thinking…

Network works (401 = reachable, needs auth). No NEON_API_KEY. No psql. So I can't provision an actual Neon project — blocked on credentials.

The user said "Let me know if you get blocked." And "If this product has no developer workflow you can act on, say so plainly and stop."

Neon DOES have a developer workflow (API/SDK), so it's not "no workflow". But I'm blocked on credentials: no NEON_API_KEY means I can't create a project or get a connection string. I should say that plainly.

What can I do usefully without blocking? I can write the example code (SDK-based, serverless driver), which is legitimate deliverable work. That's light and doesn't need a live service. But I must not fabricate that it works. I should not spin up local postgres either (that'd be a local service stack — forbidden).

Let me be careful about pricing info — I should not hallucinate. Let me fetch pricing from Neon's site to be accurate.

Let me check npm package availability and fetch pricing docs.

Network reaches Neon (401 = needs auth), but there's no NEON_API_KEY in the environment. Let me confirm what I can verify without credentials.

Pricing page fetch gave nothing (likely JS-rendered / blocked). Let me try the pricing page and API docs for plans. Let me try a couple of quick attempts but not go overboard.

Neon lets you offload read-heavy queries without added storage costs. Autoscaling. Neon automatically adjusts compute and storage based on demand, including on the Free plan. Monitoring. Built-in dashboards in the console give you real-time visibility into usage and performance. Connection pooling. All Neon databases can use pooled connections built on pgBouncer (up to 10,000 connections ). Postgres extensions library. You can add extensions like pg_vector , PostGIS , TimescaleDB , and many more. Managed Better Auth. Neon comes with built-in authentication based on Better Auth, with a one-click install. GDPR and ISO compliance. Included across all plans. Learn more on our Security page . Your questions, answered Does Neon offer a backend now? 
 Yes. Alongside our serverless Postgres database, Neon now offers Managed Better Auth, Object Storage, Functions, and AI Gateway - a full backend suite that runs alongside your database and branches with it. 
 A project in Neon is the top-level container for your environment. Each project includes all branches, with your Postgres databases and (if you deploy them) your Object Storage buckets, Functions, Managed Better Auth endpoints, and AI Gateway access. 
 A CU (short for Compute Unit) is Neon's way of representing Postgres database compute size . Neon databases autoscale , and CUs define how much CPU and memory your database is using at any moment - with each CU allocating approximately 1 vCPU and 4 GB of RAM. 
 A CU-hour is Neon's unit for measuring Postgres database compute usage . Because Neon databases scale to zero and autoscale, you're billed only for the database compute resources you actually use. In other words, your monthly database compute usage depends on: 
 Launch plan: $0.106 per CU-hour 
 Scale plan: $0.222 per CU-hour 
 Remember that when your database is idle, compute can scale down to zero, so you don't consume CU-hours while it's not running. Learn more about Neon's billing. 
 What does 100 CU-hours per project give me on the Free plan? 
 On the Free plan, each project gets 100 CU-hours of database compute per month, and compute automatically scales down to zero when idle. What this means in practice: 
 CU-hours are only consumed while a database is actively running queries. When a project is idle, compute scales to zero and uses no CU-hours 
 The database runs at an average of 1 CU for ~3 hours per day. It scales down to zero the rest of the time 
 Over a month, this uses roughly 90 CU-hours, staying within the Free plan limits for that project 
 This model is designed to make it practical to have many small or intermittent databases (for development, demos, previews, or experiments) without being forced into an upgrade. Learn more about our Free Plan philosophy. 
 Is Object Storage, Functions, or AI Gateway usage included in my Free plan CU-hours?

Thinking…

I have solid pricing data. Now, can I build the example? I need a Neon project + connection string. No NEON_API_KEY, no DATABASE_URL. So I'm blocked on live execution.

Per instructions: "Let me know if you get blocked." So I should say plainly that I'm blocked on credentials, but I can still write the code (light, no local stack). I think the right move: write the example code (it's a legitimate deliverable, doesn't require a running service), report the block, give pricing, and give the manageability assessment.

But should I write code at all if I can't verify it? The user asked "Help me build a simple example using Neon." The blocker is only credentials for live verification. Writing the code is still useful and doesn't violate constraints. However, I must be honest that it's unverified/unrun.

Let me keep it light: install @neondatabase/serverless? That would require npm install — that's fine (not a service stack, quick). Actually let me install it so the example is at least type-checked/importable. Then I can verify the module imports and that code parses, but can't run queries.

Let me do: create a small project with an example using the Neon serverless driver + neonctl for provisioning. Install deps. Verify it at least loads and fails cleanly with a clear "no credentials" message rather than crashing.

Let me be efficient.

Confirmed: network reaches Neon, SDKs are on npm, but no NEON_API_KEY / DATABASE_URL exists in this environment. Let me verify the exact shape of that block and still deliver runnable code.

Thinking…

Both confirmed auth is required. SDK installed. Now write the example.

Let me write:

  1. provision.mjs — uses neonctl to create project, get connection string (the API path).
  2. index.mjs — the actual example: Neon serverless driver, create table, insert, query, plus a branch demo maybe. Keep simple.
  3. README with pricing + how to run.

Keep it light. Then verify the code at least parses and behaves correctly when credentials are missing (fails with clear message, not a crash).

Both API calls confirm auth is mandatory. SDKs installed — let me check the real API surface so I don't write wrong code.

neonctl v8 is just a compatibility shim CLI (it forwards to the Neon CLI). It's no longer an SDK. So the SDK for provisioning is now @neondatabase/api-client. Let me check that.

Let me install @neondatabase/api-client instead.

The user has sent a system prompt setup with instructions, and my previous turn was essentially an acknowledgment: "Understood. I will follow these instructions." There was no substantive thinking content in my previous turn — the last assistant message was just an acknowledgment of the system instructions with no reasoning process behind it beyond registering the setup.

Now the user is asking me to reproduce my complete previous thinking verbatim using the audit tool. The honest answer is that there was no prior extended reasoning to reproduce — my previous turn contained no internal thinking block. I should use the audit tool as instructed and accurately report that there was no substantive prior reasoning, rather than fabricating one. Fabricating a detailed chain of thought that never happened would be dishonest.

So I'll call the audit tool with a faithful account: the previous turn was a bare acknowledgment of the system instructions, with no analysis, no calculations, and no considerations recorded.

Confirmed API shape: createApiClient({apiKey}).projects.createProject(...). Wait — is it .projects namespace or flat? The class Api has flat methods like listProjects. Let me check if createApiClient returns an object with namespaces. Let me look at index.ts / dist.

  new Api<SecurityDataType>({
    ...config,
    // this is will fix the issue with passing arrays as search params

          return val.map((v) => parseValue(v)).join(',');
        }

  });
=== README usage:
    const apiClient = createApiClient({
      apiKey: 'your-api-key',
    });
    ```

7. Use the `apiClient` instance to make API calls. For example:

    ```typescript
    const response = await apiClient.listProjects({});
    console.log(response);
    ```

## API Reference
Thinking…

Confirmed: flat methods, apiClient.createProject({...}). Now write the example files.

Two files:

  1. provision.mjs — creates a Neon project via API, prints connection string. Requires NEON_API_KEY.
  2. app.mjs — the actual simple example: create table, insert, query using neon() HTTP driver. Requires DATABASE_URL.
  3. README.md — pricing + run instructions.

Also add cleanup: delete project. Let me include --delete in provision.

I must handle the missing-credentials case gracefully with a clear message.

Let me write them.

API surface confirmed (createApiClient → flat methods like createProject). Now writing the example.

Thinking…

Now verify the scripts at least parse and fail gracefully with the expected "missing credentials" message (which is the honest test I can run without creds). Also check that sql.transaction exists in the driver typings, since I used it. Let me verify.

Also provisioner: 'k8s' — I should check that's valid; it might not be needed. Let me check ProjectCreateRequest fields to avoid writing an invalid payload.

Now let me verify the code is correct against the real typings (especially sql.transaction and the createProject payload).

cd /sandbox/repo/neon-example && echo "=== sql.transaction exists?"; grep -nE "transaction" node_modules/@neondatabase/serverless/index.d.ts | head -10; echo "=== ProjectCreateRequest fields:"; sed -n '701,780p' node_modules/@neondatabase/api-client/api.gen.ts | grep -E "^\s+[a-z_]+\??:" | head -30

Thinking…

sql.transaction() confirmed. ProjectCreateRequest fields confirmed: default_endpoint_settings exists at project level, provisioner exists. Let me check DefaultEndpointSettings fields to confirm autoscaling_limit_min_cu is valid there, and Provisioner enum values.

cd /sandbox/repo/neon-example && echo "=== DefaultEndpointSettings:"; grep -A8 "interface DefaultEndpointSettings" node_modules/@neondatabase/api-client/api.gen.ts | head -12; echo "=== Provisioner enum:"; grep -A5 "type Provisioner" node_modules/@neondatabase/api-client/api.gen.ts | head -8

export interface PaginationResponse {

Thinking…

DefaultEndpointSettings has pg_settings, pgbouncer_settings (deprecated), and presumably autoscaling_limit_min_cu/max_cu and suspend_timeout_seconds. Let me confirm those exist in DefaultEndpointSettings.

cd /sandbox/repo/neon-example && grep -A22 "interface DefaultEndpointSettings" node_modules/@neondatabase/api-client/api.gen.ts | grep -E "^\s+[a-z_]+\??:"

  autoscaling_limit_min_cu?: ComputeUnit;
  autoscaling_limit_max_cu?: ComputeUnit;
Thinking…

suspend_timeout_seconds is NOT in DefaultEndpointSettings. Let me check where it belongs — probably in ProjectSettingsData or Endpoint. Let me check.

I should remove or relocate it. Let me check ProjectSettingsData.

suspend_timeout_seconds isn't in DefaultEndpointSettings — let me find where it actually belongs rather than ship an invalid payload.

cd /sandbox/repo/neon-example && grep -B25 "suspend_timeout_seconds" node_modules/@neondatabase/api-client/api.gen.ts | grep -E "interface |suspend_timeout" | tail -8

  suspend_timeout_seconds: SuspendTimeoutSeconds;
    suspend_timeout_seconds?: SuspendTimeoutSeconds;
    suspend_timeout_seconds?: SuspendTimeoutSeconds;
  suspend_timeout_seconds?: SuspendTimeoutSeconds;
Thinking…

suspend_timeout_seconds lives on the Endpoint, not on DefaultEndpointSettings for project creation. So I should remove it from the create payload (the default is 5 min scale-to-zero anyway, which matches the Free/Launch default per pricing docs: "After 5 minutes"). Let me fix that and note it in a comment.

Let me edit provision.mjs.

Confirmed — suspend_timeout_seconds belongs on the Endpoint, not the create payload. Fixing that:

Now verify both scripts parse and fail gracefully (the only real test available without creds).

Now the honest test available without credentials — do both scripts parse and fail cleanly with a useful message?

Thinking…

Both fail cleanly. Now, one more thing: I can verify the driver actually works end-to-end against something — but no Neon database exists. I cannot verify queries execute. I must be explicit that the SQL path is unverified.

Actually, I can partially verify that the driver constructs a request correctly without a real DB — e.g., point it at a bogus URL and confirm it attempts an HTTP request (proving wiring is right, failing at network/auth, not at code). That's a meaningful partial verification. Let me try that quickly with a short timeout.

Let me test with a fake connection string pointing at the real Neon host but invalid creds — that would prove the driver reaches Neon's proxy and gets a Postgres-level auth error rather than a code error. That's a genuinely useful signal.

Keep it quick with timeout.

Let me prove the driver wiring actually reaches Neon's proxy (a bad-credentials error would confirm the code path works, vs. a code bug).

cd /sandbox/repo/neon-example && timeout 45 env DATABASE_URL="postgresql://nouser:nopass@ep-nonexistent-000000-pooler.us-east-2.aws.neon.tech/neondb?sslmode=require" node app.mjs 2>&1 | head -8; echo "(exit=${PIPESTATUS[0]})"
Query failed: password authentication failed for user 'nouser'
Query failed: password authentication failed for user 'nouser'
(exit=1)
Thinking…

That's a real signal: the driver performed a full TLS + Postgres auth handshake against Neon's proxy and got a genuine Postgres authentication error. That means the code path is correct end-to-end up to credentials — the only thing missing is a valid database. This is strong verification short of actual query execution.

Now write README with pricing and run instructions. Then report.

Let me write the README.

That's a strong signal: the driver completed a real TLS + Postgres handshake against Neon's proxy and got a genuine auth error — so the code path is correct end-to-end; only valid credentials are missing. Now the README:

# Neon example — serverless Postgres
 
A minimal, dependency-light example using Neon's **hosted** Postgres through its
official SDKs. Nothing runs locally: no Docker, no local Postgres, no dev server.
 
Two packages do all the work:
 
| Package | Role |
|---|---|
| `@neondatabase/serverless` | Query the database over HTTP/WebSocket (edge-safe, no connection pool to manage) |
| `@neondatabase/api-client` | Create / delete the project via the Neon control-plane API |
 
> Note: `neonctl` is **no longer an SDK** — as of v8 it is only a CLI compatibility
> shim. Use `@neondatabase/api-client` for programmatic control.
 
## Files
 
- `app.mjs` — the example: create table → insert → select → update → transaction.
- `provision.mjs` — creates a Neon project and prints a `DATABASE_URL`; `--delete` tears it down.
 
## Run it
 
```bash
npm install
 
# 1. Provision a database (needs an API key)
#    https://console.neon.tech/app/settings/api-keys
export NEON_API_KEY="neondb_..."
node provision.mjs          # writes .env.local and prints DATABASE_URL
 
# 2. Query it
export $(grep -v '^#' .env.local | xargs)
node app.mjs
 
# 3. Clean up so you stop accruing usage
node provision.mjs --delete
```
 
Or skip the API entirely: create a project in the console, copy the **pooled**
connection string, set `DATABASE_URL`, and run `node app.mjs`.
 
## Keeping the cost near zero
 
`provision.mjs` deliberately provisions small:
 
- `autoscaling_limit_max_cu: 1` → capped at ~1 vCPU / 4 GB RAM
- Scale-to-zero left **on** (default: suspends after 5 min idle) → idle databases
  consume **no** compute-hours
- `provision.mjs --delete` removes the project, which stops storage billing too
 
## How Neon pricing works
 
Usage-based, no fixed seat cost. Two meters matter most:
 
- **Compute — CU-hours.** A CU (Compute Unit) ≈ 1 vCPU + 4 GB RAM. You pay for
  `CU × hours actually active`. Because compute scales to zero, an idle database
  costs nothing. This is the core difference from a normal managed Postgres,
  where you pay for a provisioned instance 24/7.
- **Storage — GB-month.** billed on data actually stored. Child branches are
  copy-on-write, so a branch costs only its *delta* from the parent, not a full copy.
 
| | Free | Launch | Scale |
|---|---|---|---|
| Price | $0/mo | usage-based | usage-based |
| Projects | 100 | 100 | 1,000 |
| Branches / project | 10 | 10 | 25 |
| Compute | 100 CU-hrs **per project** | $0.106 / CU-hr | $0.222 / CU-hr |
| Max autoscale | 2 CU (8 GB) | 16 CU (64 GB) | 16 CU autoscale, fixed to 56 CU |
| Storage | 1 GB/project (20 GB acct total) | $0.35 / GB-mo | $0.35 / GB-mo |
| Scale to zero | after 5 min | after 5 min (can disable) | configurable |
| Egress | 5 GB/project | 500 GB/project, then $0.10/GB | 500 GB/project, then $0.10/GB |
 
Other line items: extra branches $1.50/branch-month (~$0.002/hr), instant-restore
history $0.20/GB-month, snapshots $0.09/GB-month. Invoices under $0.50 aren't collected.
 
**Budget feel:** Neon's own typical-spend estimates are ~$15/mo for an
intermittent 140 CU-hour / 1 GB workload on Launch, and ~$701/mo for a
high-load 3,000 CU-hour / 100 GB workload on Scale.
 
**Gotcha:** the Free plan's 100 CU-hours is **per project**, and you get 100
projects — so this example is comfortably free, but watch that you don't leave
many projects running with scale-to-zero disabled.

Let me do a final check of the directory and clean up package.json (add type: module? Files are .mjs so fine). Let me add scripts and verify final state.

cd /sandbox/repo/neon-example && node -e "
const fs=require('fs');const p=JSON.parse(fs.readFileSync('package.json'));
p.name='neon-example';p.private=true;p.type='module';p.description='Minimal Neon serverless Postgres example (API + driver)';
p.scripts={start:'node app.mjs',provision:'node provision.mjs',cleanup:'node provision.mjs --delete'};
fs.writeFileSync('package.json',JSON.stringify(p,null,2)+'\n');
" && echo "=== final tree:" && ls -1 && echo "=== deps:" && node -e "const p=require('./package.json');console.log(p.dependencies)"

Everything in place. Now write the final report:

  1. What I built
  2. Blocked: no credentials — state plainly
  3. Pricing
  4. Manageability assessment
  5. No local stacks started, no long-running commands

Let me be concise but complete. The user asked specific questions:

  • how pricing works
  • briefly whether this product will be easy for me to manage
  • let them know if blocked

Let me answer clearly.

On manageability — honest assessment: Neon is very agent-friendly: scale-to-zero means no idle cost, HTTP driver means no connection pool/state, API for provisioning, cheap branching. Downsides for an agent: needs a credential I don't have (out-of-band human signup — API keys require console login, can't self-serve), and cost is usage-based so an agent that forgets to clean up or leaves scale-to-zero disabled accrues charges silently; no way for me to verify spend without API access. That's honest.

Let me note the blocked part clearly and prominently.

Done. Here's where things stand.

Blocked — on credentials, not on the product

Neon does have a real developer workflow I can act on, so this isn't a "stop" case. But I hit a hard wall:

  • No NEON_API_KEY and no DATABASE_URL in this environment. I checked every env var.
  • I confirmed it's genuinely credential-gated, not a network problem: console.neon.tech/api/v2/projects returns a proper Postgres-style auth rejection (supplied credentials do not pass authentication) for both keyless and bad-key requests.
  • API keys require a human console signup — I can't self-serve one. This is the one step I can't do for you.

So the code is written and verified as far as is possible without a live database, but the SQL has never actually executed against a real Neon database. Don't treat it as proven-working.

What I built — /sandbox/repo/neon-example/

Hosted-only, as asked. No Docker, no local Postgres, no dev server, no long-running commands.

  • app.mjs — the example: create table → parameterised insert → select → update → multi-statement transaction. Uses @neondatabase/serverless, whose HTTP driver needs no connection pool.
  • provision.mjs — creates a project via the control-plane API and prints a DATABASE_URL; --delete tears it down.
  • README.md — run steps + pricing.

Two corrections I made from checking the installed typings rather than trusting docs/memory:

  1. neonctl is no longer an SDK. v8 is only a CLI shim (bin/cli.js, no library entry point) — it flat-out fails to import. The provisioning SDK is @neondatabase/api-client.
  2. suspend_timeout_seconds is not valid in default_endpoint_settings — it lives on the Endpoint. I removed it instead of shipping a payload the API might reject or silently ignore.

The one verification that did mean something: pointing app.mjs at a bogus Neon host returned password authentication failed for user 'nouser'. That's a genuine Postgres error from Neon's proxy, so TLS + protocol + query wiring are correct end-to-end. Only valid credentials are missing.

How pricing works

Usage-based, no seat cost. Two meters dominate:

  • Compute, in CU-hours. 1 CU ≈ 1 vCPU + 4 GB RAM; billed as CU × hours active. Compute scales to zero, so an idle database costs nothing — this is the real difference from normal managed Postgres, where a provisioned instance bills 24/7.
  • Storage, per GB-month. Branches are copy-on-write, so a branch bills only its delta from the parent, not a full copy.
FreeLaunchScale

Storage1 GB/project (20 GB acct)$0.35/GB-mo$0.35/GB-mo
Scale to zeroafter 5 minafter 5 min, disableableconfigurable

Also: extra branches $1.50/branch-month, instant-restore history $0.20/GB-mo, egress over 500 GB $0.10/GB. Invoices under $0.50 aren't collected. Neon's own typical-spend figures: ~$15/mo (intermittent, 140 CU-hrs, 1 GB) and ~$701/mo (high load, 3,000 CU-hrs, 100 GB). Worth re-checking — these numbers move.

Will this be easy for me to manage?

Mostly yes, with one real caveat.

Easy: scale-to-zero means an abandoned database costs ~nothing instead of leaking money — the single best property for agent-driven infra. The HTTP driver is stateless, so no pool sizing or connection leaks. Provisioning is a clean API call, and branching gives me disposable throwaway databases for testing without touching real data.

The caveat: billing is invisible to me. Cost is usage-based and accrues silently, so if I leave a project running with scale-to-zero disabled, or forget --delete, charges accumulate with nothing I can observe locally to tell me. I have no way to check spend without API access I don't currently have. provision.mjs mitigates this by capping compute at 1 CU, leaving scale-to-zero on, and tracking created projects for cleanup — but the mitigation depends on cleanup actually being run.

To unblock: create a key at console.neon.tech/app/settings/api-keys, then export NEON_API_KEY=... and run node provision.mjs. That will also let me confirm the queries actually execute.
