REQUIRES a `identifiers` object containing ONLY `email` and/or `linkedin_url`. `first_name`/`last_name`/`domain` are NOT accepted — if you only have a name + company, call `/people/email-finder` first. `linkedin_url` is the strongest signal. agntdata waterfalls across providers that expose mobile data, cheapest-first, until a number is found or your budget is exhausted. ## OpenAPI ````yaml /openapi/agnt.openapi.json post /v1/data/agnt/people/find-mobile 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).
