Identifier fields are at the TOP LEVEL of the body (NOT inside an `identifiers` object): `first_name` + `last_name` (or `full_name`) plus `domain` (or `company` / `company_name`). LinkedIn URL/handle is not currently supported here — if that is all you have, call `/people/enrich` first with `identifiers.linkedin_url` to resolve name + domain, then call this endpoint. agntdata waterfalls cheapest-first across providers until an email is returned (or your `max_cost_cents` budget is exhausted). If you already know the email and want to look up other fields, use `/people/enrich` instead with `identifiers.email`. ## OpenAPI ````yaml /openapi/agnt.openapi.json post /v1/data/agnt/people/email-finder openapi: 3.0.0 info: title: agntdata Lead APIs description: >- Internal lead enrichment API surface that orchestrates multiple upstream data providers behind a single endpoint per use case. Use these endpoints to find and verify professional emails, find mobile phone numbers, enrich and search people and companies, discover companies, list a domain's email addresses, run bulk people/company enrichments, and fetch company intelligence (funding/competitors/technographics).
