# Email and phone data API for AI agents

looot lists the email and phone operations of many contact data providers in one catalog. An agent finds a work email from a name and domain, verifies an address, finds a mobile number from a profile link, or reverses an email to the person. Each call shows its price first.

## Jobs an agent does

- Find the work email of a prospect from a name and a company domain.
- Verify a list of addresses before a cold email send.
- Find a mobile number from a LinkedIn profile link.
- Check which profile sits behind an inbound email.
- Fall back to a second provider when the first returns nothing.

## Operations by job

- Verify an email: Checks that an address exists and can receive mail, with catch-all and disposable checks.
- Find a phone number: A direct dial or mobile number from a profile link, an email, or a name with a company domain.
- Reverse lookup: The profile or person behind an email address.
- Find a work email: A professional email from a name and a company domain, or from a profile link.

## How the providers differ

Providers differ on what they need and when they charge. Several charge only when they find a result, and the operation description says so. Some start from a name and a domain, others from a profile link, and the phone finders also accept an email. Findymail notes it returns no result for EU citizens, for legal reasons. Run two providers on a small sample before you pick one for a large list.

## Prompt

Use looot to find the work email of Jane Doe at example.com with two providers, verify both results, and show the price of every call before you run it. Setup is in skill.md.

## What can an agent find with these operations?

Work emails from a name and domain, emails from a profile link, mobile numbers and direct dials, verification of an address, and a reverse lookup from an email to a profile.

## Do I need an account with each provider?

No. Your agent calls every provider with one looot key. You do not sign up with each one or manage their credits.

## Am I charged when nothing is found?

It depends on the provider. Several charge only when they find a result, and the description of each operation says how it bills. Read it before a large run.

## How do I verify an email before sending?

Use a verify or validate operation. It reports whether the address exists and can receive mail, and flags catch-all domains. Some also return a score and checks such as disposable and webmail.

## What does a phone finder need as input?

A LinkedIn profile URL works for most. Some also accept an email, or a name with a company domain. The input line on each operation lists what it takes.

## Is there a legal limit on using the results?

Rules on outreach differ by country and by use. At least one provider returns no result for EU citizens, and the catalog notes it. Check the rules that apply to you before you contact anyone.

## How does my agent call a Email and phone operation?

It connects to looot once, searches the catalog for the job, reads the input fields and the price, then runs the operation. Setup takes one line from skill.md, and the same key works for every provider.

## How is a Email and phone call billed?

Per call, at the price shown on this page for that operation. The agent sees the price before the run, and the run is recorded with its cost in your ledger.

## Where do I find the full input and output fields?

Each operation has a reference page on docs.looot.ai with its input fields, an example call and the response. The For agents card on this page links the cheapest ones.

## Are the prices on this page current?

They are read from the live looot catalog every few minutes, so they change when a provider changes its price. When the catalog cannot be read, the page shows no numbers.

## Which Email and phone operation should I start with?

Start with the cheapest operation in the job you need, which is listed first in its group. Check that it returns the fields your agent reads, and switch to another provider if it does not.
