API Catalog SEO
API Catalog SEO is the practice of making public APIs discoverable and understandable to search engines, developers, and AI agents.
For agentic search, a public API is not only developer documentation. It is also a machine-usable capability surface.
What to Expose
- A stable API documentation URL
- An OpenAPI description when possible
- Authentication requirements
- Rate limits and pricing
- Terms of use
- Example requests and responses
- Changelog or version policy
Agent SEO Pattern
The best pattern is to link API metadata from multiple places:
- Developer documentation
- XML sitemap
- Link headers
/.well-known/discovery files where appropriate- MCP server card if tools exist
