Fern API catalog before agent scrape guesswork
Expose a standards-based API catalog before expecting agents or API crawlers to reverse-engineer your docs from HTML and navigation chrome.
Why this can grow a startup
A docs site can look clear to a person while still being awkward for machines to parse. Fern's API catalog feature fixes that by publishing a machine-readable map of visible APIs with both the human reference URL and the underlying spec link. That matters because the discovery job shifts from scraping to retrieval. Instead of hoping an agent stumbles into the right endpoint page, you give it a clean front door.
Company example
Fern documents an RFC 9727 `/.well-known/api-catalog` endpoint that is generated from visible API Reference navigation and advertised via a `Link` response header.
Source and metric
Source: Fern Docs: API catalog discovery
Fern says the API catalog is generated automatically with no configuration required and includes `anchor`, `service-desc`, and `service-doc` links for each visible API.
When to use it
Use this when API docs, AI visibility, Developer Tools is relevant to api discovery, agent retrieval, machine-readable docs and you can run a bounded test with a low budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read Fern Docs: API catalog discovery and identify what is directly supported.
- Choose one channel context: API docs, AI visibility, Developer Tools.
- Define the test around Fern says the API catalog is generated automatically with no configuration required and includes `anchor`, `service-desc`, and `service-doc` links for each visible API..
- Set an owner, evidence window, and stop condition before launch.
