Every source below answers one question: where do your future clients show up? Click any source to see exactly which filter parameters each endpoint accepts and which fields it returns — plus the price per 1,000 requests. Same API you already use: same auth, same JSON.
How pricing works. Billing is per request, priced per endpoint — simple lookups start at $5 / 1,000 requests; heavier extractions (full registry dossiers, premium people-search) cost more and are listed on each endpoint below.
Billing is per request, not per returned record: a request that returns 1 record costs the same as one returning a full page. Where the price says "per N results", each started page of N results counts as one request; "per request" means a flat rate per call regardless of how many records come back.
All prices are exact per endpoint. Volume discounts from 1M requests / month. Prices in USD.
