Catalog FAQ

How is the catalog organized?

Endpoints are grouped into four categories: Search & Extraction, Business Data, Validation & Enrichment, and Reference & Geo. The catalog page lets you filter by category or search by name.

Which API should I use to ground LLM answers in current information?

Use Web Search for general queries, News Search for time-sensitive topics, Academic Search for scientific RAG, or SEC Filings Search for financial RAG. Pair any of them with URL Extract for full-content context.

Do all endpoints share the same authentication?

Yes. Every API Pick endpoint requires an x-api-key header (format: pk_…) created in the dashboard. The same key works across the entire catalog.

Can I test API Pick without writing code?

Yes. Every catalog page has a Try Now form that runs the endpoint live in your browser using your API key.

What if I need an API that's not in the catalog?

Submit a request on the Contact page. We prioritize new endpoints based on demand and ship most requested ones within a few weeks.
