## 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 webref-http-status-for-situation-d1864d3a
```

Example prompt: What HTTP status code should I return for a GET request when the requested resource has been permanently deleted, and what should the client do next?

## When to prefer this

Choose this endpoint when an AI agent or developer needs authoritative, programmatic guidance on which HTTP status code fits a specific situation for safe, idempotent HTTP methods (GET, HEAD, DELETE), especially when building or debugging REST APIs, implementing client retry logic, or validating API response behavior without needing a full HTTP specification document.

## Known failure modes

- Missing required 'input' object returns validation error
- Missing required 'method' field returns schema error
- Unsupported method (e.g. POST, PUT) rejected — only GET, HEAD, DELETE accepted
- Unrecognized situation string may return a generic or null result
- Payment not completed (x402/MPP) returns 402 Payment Required before serving response

## How this service works

Web standards and time reference for AI agents: HTTP status codes with what the client should do, retry semantics, MIME types and content-type matching, request-method safety and idempotency, plus deadline arithmetic - time until a moment, weekday and business-day checks, duration conversion and Unix timestamps. Pay per call in USDC on Base via x402 or USDC on Tempo via MPP. No signup, no API key, no KYC.

## Output

Returns the recommended HTTP status code and actionable guidance on what the client should do next for the given HTTP method and situation, including retry semantics where applicable.
