Lead recipe 3

Add Forager as a waterfall step in an agent's contact tool

When to use it: An agent's find-contact tool returns nothing for a third of prospects because its single source has no mobiles.

Show the steps
  1. Define one find_contact tool in your framework that takes a LinkedIn URL or name and company
  2. Inside it, call POST /person_contacts_lookup/phone_numbers/ then POST /person_contacts_lookup/work_emails/ when the earlier source returns nothing
  3. Return a typed result with the field names, the source that found it and the person_id
  4. Count credits per found result only, so a miss in the Forager step adds 0 to the run's cost

FAQ

Frequently asked questions

How do AI agent and developer-tool companies use Forager mobile numbers?

Find verified practitioners (radiologists, tax attorneys, actuaries) to write and grade data for AI labs instead of generic labelers. Direct mobile numbers for a person, from a LinkedIn URL or a Forager person ID, validated before they reach you. This page walks through 3 workflows with the exact steps.

What do mobile numbers cost for AI agent and developer-tool companies?

Mobile numbers: 15 credits per mobile number found, and a mobile number lookup that finds nothing costs 0 credits. That is $0.20 per mobile number on Starter month to month and $0.15 on Pro with yearly billing. Self-serve plans are Starter, Growth, Pro and Scale. See plans and prices

Which AI agent and developer-tool workflows use mobile numbers?

Recruit domain experts for AI model evaluation and training data, offer people and company data as a built-in integration in an AI app builder and add Forager as a waterfall step in an agent's contact tool. Each is on this page with its trigger, steps and outcome.

How do I recruit domain experts for AI training data?

Query people_feed or POST /person_role_search/ for credentialed titles and experience length. Filter by location and current employment for availability.

What inputs does it take and what does it return?

You send cohort size, company domain and expert profile spec. You get back phone_number, work_email, company and contact fields, from POST /person_contacts_lookup/phone_numbers/, as JSON.

Am I charged when no mobile number is found?

No. A mobile number lookup that finds nothing costs 0 credits, so you pay for mobile numbers we find. Search, enrichment and reverse lookups are the exception: they are charged per request.

Can AI agent and developer-tool companies test mobile numbers for free?

Yes. Create a free account at app.forager.ai: it comes with $5 in free credits and an API key, and there is no credit card to sign up. Run it on records you already know, or book a demo and send us a list: we run it and show you what we find.

How do I add contact enrichment to a vibe coded app?

When generated code needs contacts, call /person_contacts_lookup/work_emails/ and POST /person_contacts_lookup/phone_numbers/ through the platform's metered key. For card or badge capture apps, OCR the name and company and resolve the person with POST /person_detail_lookup/.

How do you check data quality?

Forager ranked #1 of 10 in Clay's 2026 test of mobile data providers, by quality score: Clay's measure of how likely a dialled number reaches the right person. The test that counts is your own: send a list of profiles you care about. We run it and show you what we find, number by number, so you can measure hit rate and connect rate yourself.

How is a mobile number lookup API different from a contact database?

A contact database sells access to a list, often by seat or by export. A lookup API answers one person at a time inside your product or workflow: you send the LinkedIn URL or email you already hold and get back a mobile number in one JSON response. With Forager a mobile number lookup that finds nothing costs 0 credits, so you pay for numbers, not for searches.

Where can I use Forager mobile numbers?

Native in Clay and Zapier, partner-built in Deepline and Cargo and called through the API from Make, n8n and your own code. Everything else connects through the REST API with one API key.

Do I need a subscription?

Not to test: a free account comes with $5 in credits. To keep using mobile numbers, choose a monthly or yearly plan. Monthly plans cancel anytime and unused credits roll over; yearly plans grant all credits upfront and cost 10% less. Larger volumes are agreed with our team.
