Overview

agntdata Lead APIs sit on top of multiple upstream lead-data providers and expose a single unified surface per use case (email finder, email verifier, person/company enrich, person/company search, company discovery, domain emails, mobile finder, company intelligence). For each call you can pass an optional `fields[]` selector and an optional `max_cost_cents` budget — agntdata then waterfalls cheapest-first across providers that can fulfill those fields, stops as soon as the request is satisfied (or your budget runs out), and merges results into a normalized response shape. Provider names are never returned in the response. Pricing is hybrid: simple endpoints (e.g. email verifier, intelligence signals) are flat-priced; complex waterfalls (enrich, email finder, find-mobile, search) are billed in the published `min – max` cents range based on what was actually spent upstream, plus a small markup. Bring one API key, get one bill, and let agntdata handle vendor selection, key rotation, and result merging.
