# GraphQL API Security

## Purpose
Comprehensive GraphQL API testing: schema intelligence, authorization bypass, resource consumption, and mutation abuse.

## Preconditions
- A GraphQL endpoint has been identified (POST to /graphql or similar)
- At least one valid session (for authenticated queries)

## Attack Surface Signals
- POST to /graphql, /query, /api/graphql, /v1/graphql
- JSON responses with `data`/`errors` structure
- Apollo/Relay/urql client libraries in JavaScript
- `Content-Type: application/json` with `query` in the body
