description	Entry P1 category router for API security. Use when choosing between API recon, authorization, token abuse, and hidden-parameter workflows before any deeper API topic skill.

API Security Router

This is the routing entry point for API security testing.

Use this skill first to decide whether the API issue is mostly recon/docs, object authorization, token trust, or GraphQL/hidden parameters, then route to a deeper topic skill.

When to Use

• The target exposes REST APIs, mobile backends, or GraphQL endpoints
• You need to define API testing order before going into specific topics
• You want to handle object authorization, JWT, GraphQL, and hidden fields as separate tracks

Skill Map

• API Recon and Docs: OpenAPI, Swagger, version drift, hidden documentation
• API Authorization and BOLA: BOLA, BFLA, method abuse, hidden writable fields
• API Auth and JWT Abuse: bearer token, header trust, claim abuse, rate-limit bypass
• GraphQL and Hidden Parameters: introspection, batching, undocumented fields, hidden parameters

Quick Triage

Observation	Route
Swagger or OpenAPI is present	api-recon-and-docs
IDs appear in URL, JSON, headers, or GraphQL args	api-authorization-and-bola
JWT token visible in traffic	api-auth-and-jwt-abuse
/graphql or batched JSON arrays are present	graphql-and-hidden-parameters
Registration, login, or profile updates accept extra fields	api-authorization-and-bola then api-auth-and-jwt-abuse

Recommended Flow

1. Start with exposed endpoints and documentation assets
2. Then evaluate object-level and function-level authorization
3. Then evaluate token, header, signature, and rate-limit boundaries
4. If GraphQL or complex JSON is present, continue with hidden fields and schema abuse
