OpenAI-compatible chat completions endpoint, pay-per-call via x402 micropayments with no API key required

## Facts

- Endpoint: POST https://netintel.dev/api/v1/chat/completions
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability netintel-chat-completions-api-f3c770b3 -d '<json body>'
```

Example prompt: Ask gpt-4o-mini to summarize the following paragraph in two sentences — no API key needed, just pay per call: 'Artificial intelligence is transforming industries by automating complex tasks, enabling new forms of creativity, and reshaping how people interact with technology.'

## When to prefer this

Prefer this endpoint when you need OpenAI-compatible chat completions without an API key or account signup, especially in autonomous agent contexts where pay-per-call USDC micropayments via x402 are preferred over subscription billing. Ideal for one-off inference tasks, pipelines that need anonymous LLM access, or situations where you want guaranteed no-charge on failures.

## Known failure modes

- Invalid or unsupported model ID returns an error with no charge
- Malformed messages array (missing role or content) triggers input validation rejection with no charge
- Upstream model provider failure results in no charge per NetIntel's fair-trade policy
- Exceeding max_tokens cap silently clamps to model maximum
- Payment failure or insufficient USDC balance blocks the request before processing

## How this service works

OpenAI-compatible chat completions gateway (alias of /v1/chat/completions for api/v1-style base URLs) — standard request shape, model chosen in the body: any gpt-* chat model (not Claude/embeddings), each at its own price. Priced per model, $0.005–$0.65 per call in USDC via x402, no API key: POST unpaid and the 402 quotes your model's exact price. Supports response_format json_object. Free model catalog: GET /v1/models.

## Output

Returns an OpenAI-compatible chat.completion JSON object containing the generated assistant message, finish reason, model used, and token usage stats (prompt, completion, and total tokens).
