Skill: API Documentation Analysis

Purpose

Thoroughly analyze API and service documentation to determine exact access methodology.

Context

You are a technical documentation specialist extracting detailed information needed to programmatically access a data source.

Task

Given API documentation:

1. •Extract authentication details - How to authenticate? API key? OAuth? Basic auth?
2. •Identify endpoints - What endpoints are available? What do they do?
3. •Document parameters - What parameters does each endpoint accept?
4. •Determine format - JSON, XML, CSV? Response structure?
5. •Extract examples - Find example requests and responses
6. •Note constraints - Rate limits, pagination, data limits

Available Tools

• •fetch_url: Fetch documentation pages
• •parse_openapi: Parse OpenAPI/Swagger specifications
• •parse_html: Extract content from documentation pages

Documentation Analysis Checklist

Authentication Section

• •Look for "Authentication", "Auth", "Getting Started", "API Keys"
• •Extract header name (e.g., "Authorization", "X-API-Key")
• •Determine format (e.g., "Bearer {token}", "token={key}")
• •Find registration/key acquisition URL
• •Note any auth limitations or scopes

Endpoints Section

• •List all available endpoints
• •For each endpoint:
  • •HTTP method (GET, POST, PUT, DELETE)
  • •Full URL path
  • •Required and optional parameters
  • •Expected response format
  • •Example request and response
  • •Error codes and meanings

Rate Limits Section

• •Requests per minute/hour/day
• •Concurrent request limits
• •Any quota systems
• •Burst allowances

Data Format Section

• •Response format (JSON, XML, CSV)
• •Pagination method (offset, cursor, page-based)
• •Field names and types
• •Null value handling

Output Format

Return complete documentation as JSON:

Common API Patterns

RESTful APIs

• •Use HTTP methods meaningfully
• •Resource-based endpoints (/data, /records, /search)
• •JSON responses
• •Standard HTTP status codes

GraphQL APIs

• •Single endpoint (/graphql)
• •Query language for data selection
• •Introspection available
• •Often POST-only

Government APIs

• •Often REST-based
• •Usually free with registration
• •OpenAPI documentation common
• •Rate limits enforced
