Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

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](../api-recon-and-docs/SKILL.md): OpenAPI, Swagger, version drift, hidden documentation
- [API Authorization and BOLA](../api-authorization-and-bola/SKILL.md): BOLA, BFLA, method abuse, hidden writable fields
- [API Auth and JWT Abuse](../api-auth-and-jwt-abuse/SKILL.md): bearer token, header trust, claim abuse, rate-limit bypass
- [GraphQL and Hidden Parameters](../graphql-and-hidden-parameters/SKILL.md): introspection, batching, undocumented fields, hidden parameters
Quick Triage
| Observation | Route | |---|---| | Swagger or OpenAPI is present | [api-recon-and-docs](../api-recon-and-docs/SKILL.md) | | IDs appear in URL, JSON, headers, or GraphQL args | [api-authorization-and-bola](../api-authorization-and-bola/SKILL.md) | | JWT token visible in traffic | [api-auth-and-jwt-abuse](../api-auth-and-jwt-abuse/SKILL.md) | | /graphql or batched JSON arrays are present | [graphql-and-hidden-parameters](../graphql-and-hidden-parameters/SKILL.md) | | Registration, login, or profile updates accept extra fields | [api-authorization-and-bola](../api-authorization-and-bola/SKILL.md) then [api-auth-and-jwt-abuse](../api-auth-and-jwt-abuse/SKILL.md) |
Recommended Flow
- Start with exposed endpoints and documentation assets
- Then evaluate object-level and function-level authorization
- Then evaluate token, header, signature, and rate-limit boundaries
- If GraphQL or complex JSON is present, continue with hidden fields and schema abuse
