The user wants to build a simple example using Nous Research (Nous Research has an API — api.nousresearch.com, which provides models like Hermes 4). Let me check the environment: is there an API key? Let me look at the repository and environment variables.

The repository is empty, and there's no Nous API key in the environment. Nous Research's API (Nous Portal, api.nousresearch.com) requires an API key obtained from a subscription. It's OpenAI-compatible. Even without a key, I can write code examples, but I can't actually run them. Should I check whether the gateway key works? PI_GATEWAY_API_KEY is for pi's model gateway, not for Nous.

The user is saying "if you get stuck, let me know." Since there's no Nous API key, I can't actually execute calls. It's possible to create sample code. However, the instructions say "if this product doesn't have an executable developer workflow, clearly state that and stop." Nous Research does have a developer workflow (OpenAI-compatible API + SDK). But without credentials, testing will be blocked.

Let me check whether a NOUS_API_KEY might be hidden somewhere.

Nous API key is unavailable. Nous Research does have a developer workflow — an OpenAI-compatible API at api.nousresearch.com/v1, with models like Hermes-4-405B, gated behind a Nous subscription (Hermes/Nous Portal subscription). Pricing: Nous uses subscription tiers rather than pure per-token pricing? Actually, the Nous Research API (portal.nousresearch.com) provides subscription-based access — subscription plans (e.g., $10/month Hermes tier?) include API access to their models, rather than pay-per-token. Historically, Nous offered API credits via subscription: Researcher tier, etc. Should be honest about uncertainty.

Can write a sample (OpenAI-compatible), but without an API key can't execute — that's a blocker. User said "let me know if you get stuck". Should I still write the sample? "Help me build a simple example" — yes, create the code files, tell them I'm blocked from running without a NOUS_API_KEY, explain pricing, and assess maintainability.

Let's create a minimal Python or Node example. The repo is empty except for .gitignore. Check the contents of .gitignore to infer the language.

Does Python's openai import without any issues? The output only shows node errors. In other words, python3 -c "import openai" didn't produce any errors — the openai package is installed.

Nous Research API: OpenAI-compatible, base URL is https://api.nousresearch.com/v1. Models: Hermes-4-405B, Hermes-4-70B, etc. Pricing: Nous Portal subscriptions — API access is tied to subscription plans. From memory: Nous Research offers subscriptions (e.g., "Hermes" around $10/month, "Researcher", etc.) that come with an API allowance. Rather than strict per-token pricing. I'm not fully confident about the current plans, so I'll explain honestly and cautiously.

I'll create a sample file and attempt to run it — it will fail because there's no API key. That's the blocker to report. I'll create a sample and a README, then report afterward.

The repository is empty, and Python's openai package is available. Since Nous Research's API is OpenAI-compatible, I can build a lightweight hosted-API example without any local stack. I'll write it now.

Let's try running it and confirming that we're blocked (no key). A simple check without long-running commands.

Confirmed: Blocked due to the lack of NOUS_API_KEY. Reporting to the user: overview of pricing, ease-of-management assessment, and the blocker.

Pricing: Nous Research does not use conventional per-token metered billing; API access is tied to a subscription via the Nous Portal. From what I know, there are subscription plans that include API access to the Hermes model. Since the current plans and pricing may have changed, I should be honest about the uncertainty and recommend checking the portal. Keep it concise.
