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 agent-data-tools-http-status-code-lookup-5ea60494
```

Example prompt: What does HTTP status code 429 mean — is it a client error or server error, and should I retry the request?

## When to prefer this

Use this endpoint when an AI agent or workflow needs to programmatically interpret an HTTP status code — especially to decide whether to retry a failed call, classify errors, or present a human-readable explanation. It is purpose-built for agent toolchains and costs only $0.001 USDC per call with no API key required.

## Known failure modes

- Invalid or unrecognized status code integer returns an error or empty result
- Missing required 'code' query parameter causes request failure
- Non-integer value for code parameter is rejected by schema validation

## How this service works

HTTP status code meaning. Name and plain-language meaning of an HTTP status code (1xx-5xx, including 402 Payment Required and 429 Too Many Requests), and whether to retry. Use when handling API errors.

## Output

A JSON object containing the numeric code, its official name (e.g. 'Too Many Requests'), its class (e.g. 'client error' or 'server error'), a boolean retry flag indicating whether the caller should attempt the request again, and a plain-English meaning string describing the situation.
