# 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

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

### Common documentation and schema paths

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

### Version and product drift

```text
/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
