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 ciel-m2m-api-marketplace-graphql-fuzzer-5c6cfbb3 -d '<json body>'
```

Example prompt: Run a GraphQL fuzzer scan against my API — I want to discover any hidden fields, exposed mutations, or security weaknesses. Pass the target schema properties as a string and give me back what it finds.

## When to prefer this

Choose this endpoint when you need automated GraphQL-specific security fuzzing and field discovery rather than general HTTP vulnerability scanning or REST API testing. Particularly suited for AI agents performing pre-deployment security audits or continuous API monitoring within a pay-per-call workflow.

## Known failure modes

- Malformed properties string returns generic error response
- Unreachable or non-GraphQL target may return empty results
- Schema too large may cause timeout or truncated response
- Invalid JSON in properties field causes request rejection

## How this service works

## Output

Returns a JSON object with fuzz results including discovered fields, exposed mutations, potential injection points, introspection data, and any security anomalies found during the scan.
