# Aizamon OpenAPI Spec Linter

> Aizamon OpenAPI Spec Linter is a paid API for AI agents from aizamon.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Validates an OpenAPI JSON specification by checking version, paths, and presence of at least one 2xx response, returning a structured lint score and issue list.

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 aizamon-openapi-spec-linter-4542f86a
```

Example prompt: Can you lint this OpenAPI JSON for me and tell me what's wrong with it? I want to know if it has valid version info, correct paths, and at least one 2xx response defined.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.02) automated lint pass on an OpenAPI JSON document — especially to verify version field, path structure, and presence of 2xx responses. Ideal for CI pipelines, pre-publish checks, or agent workflows that generate OpenAPI specs and need to self-validate. Not a full schema compliance tool; use it for rapid structural checks rather than exhaustive validation.

## Known failure modes

- Missing or invalid 'q' query parameter returns an error
- Non-JSON or malformed OpenAPI input may produce a low score with multiple issues
- Network or payment settlement failure returns a 402 Payment Required
- Empty or null OpenAPI JSON may fail schema validation before linting begins

## How this service works

Aizamon is an operator-run Canadian shop: $5 emailed security summaries via Stripe, Tor tooling for Cursor, and redacted developer telemetry. Named support. Clear terms.

## Output

A JSON object containing: 'ok' (boolean success flag), 'sku' (SKU_AG_SPEC_01), 'protocol' (x402), and 'result.openapi' with a numeric score and an array of issue strings describing problems found (e.g. 'missing 2xx response', version errors, path problems).
