Frequently asked questions

What is the difference between cache and live freshness?

cache answers from the stored snapshot without touching the upstream; live queries fresher data and may cost extra credits — see the freshness section of the docs.

Can I try this endpoint for free?

Yes — register an account, grab an API key and call it from the Playground in the console.

How is the search_posts capability billed?

Data API calls are billed per request in credits, with different cache/live freshness multipliers. Current per-capability prices live on the pricing page.
