SKILL: API Recon and Docs — Endpoints, Schemas, and Version Surface

AI LOAD INSTRUCTION: Use this skill first when the target is a REST, mobile, or GraphQL API and you need to enumerate endpoints, documentation, versions, and hidden surface area before exploitation.

1. PRIMARY GOALS

1. Discover all reachable API entrypoints.
2. Extract schemas, optional fields, and role differences.
3. Identify old versions, mobile paths, GraphQL endpoints, and undocumented parameters.

2. RECON CHECKLIST

JavaScript and client mining

curl https://target/app.js | grep -oE '(/api|/rest|/graphql)[^"'\'' ]+' | sort -u

Common documentation and schema paths

/swagger.json
/openapi.json
/api-docs
/docs
/.well-known/
/graphql
/gql

Version and product drift

/api/v1/
/api/v2/
/api/mobile/v1/
/legacy/

3. WHAT TO EXTRACT FROM DOCS

• optional and undocumented fields
• admin-only request examples
• deprecated endpoints that may still be active
• schema hints like additionalProperties: true
• parameter names tied to filtering, sorting, IDs, roles, or tenancy
