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.
Source-backed 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-reported evidence
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.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to API docs and AI visibility, using evidence from Fern Docs: API catalog discovery as context—not as a promised result.
- Record a baseline for: Target users who complete the tactic’s intended next action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
