Billing & credits
The API is metered against a shared credit wallet — the same credits the web app spends. X-Credits-Remaining is returned on every response.
What a call costs
Detail lookups cost 0.3 credits, resolve-with-rollup calls 0.6, and searches 1.5. The /health endpoint is free and unauthenticated.
Running out
When your balance cannot cover a call the API returns 402 (insufficient_credit). Subscribe to Plus, or move to a higher Plus tier, to resume.
