Find the right API
Use search when the broad directory stops being enough. Filter by category, auth, CORS, signup friction, and result freshness until the shortlist becomes obvious.
Start with category and auth when you know the integration shape. Use free, signup, and CORS flags when you are trying to remove setup friction.
Sort by verification or response time when the final call is about reliability, not just category fit.
