Frequently asked questions

Up to 100 domains per request. Send a JSON array of domain strings in the domains field of the request body. Each domain costs 1 credit, so a batch of 100 domains costs 100 credits total.
The response includes both a companies array (found records) and a not_found array (domains without matches). The found count tells you how many succeeded. You’re only charged credits for domains that return data.
Both endpoints return the same full company profile including description and specialties. The batch endpoint just lets you look up multiple domains in one HTTP request instead of making individual calls, which is faster and more efficient for large lists.
