FAQ

Frequently asked questions

How do LLM apps use Forager reverse email lookup?

Keep an AI CRM's company and contact records current so its agents score inbound, prefill onboarding and flag churn risk accurately. Turn an email address into a full person profile: name, title, company, location and social links. This page walks through 3 workflows with the exact steps.

What does reverse email lookup cost for LLM apps?

Reverse email lookup: 5 credits per request, charged whether or not data comes back. 1,000 reverse email lookups use 5,000 credits: about $67 of Starter credits month to month, or about $50 on Pro with yearly billing. Self-serve plans are Starter, Growth, Pro and Scale. See plans and prices

Why do LLM apps add reverse email lookup?

Answer people questions with licensed data, not scraped pages. Products like yours are judged on whether the agent reached the right person, which is why the cost that counts is per result that reaches the right person. Run your own sample to see what reverse email lookup returns for your users before you build on it.

How do AI CRMs keep company data fresh for their agents?

Load company_feed and people_feed deltas into the CRM's records store. Expose records to agents as retrieval context with field-level timestamps.

What do I send, and what comes back?

You send email address, API key and calendar attendee. You get back person_id, agent context, company and company summary, from POST /person_detail_reverse_lookup/by_email/, as JSON.

Can we show Forager data inside our product?

Yes, under platform terms. Self-serve plans cover internal use by your own team. Showing Forager data to your users, or passing records on, is licensed separately: talk to sales about volume and which fields your users need to see.

Am I charged when nothing is found?

Yes. Reverse email lookup is charged per request, whether or not data comes back. Only mobile and email lookups are free when nothing is found, so try your inputs on a small run before you scale.

Is there a free way to try Forager?

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 enrich calendar attendees with job title?

Resolve each new email address with POST /person_detail_reverse_lookup/by_email/. Pull full career history with POST /person_detail_lookup/.

How accurate is Forager data?

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.

What is the difference between a reverse email lookup and an email finder?

An email finder starts from a person and returns their email. A reverse email lookup starts from an email address, such as a sign-up or an inbound lead, and returns the person behind it: name, title, company, location and social links.

Does Forager integrate with the tools we already use?

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