Agent skill, easy

Find a phone number, as a skill your agent installs.

Phone number finder API for an agent: it sends a LinkedIn profile URL, an email, or a name and a company domain to a catalog endpoint and reads phone number, line type and country code back. Several providers sell the call, so the agent tries the cheapest first. You pay per call, and a failed call costs nothing.

Install

How do I install this skill?

Two steps. Set up looot once, then save this skill file where your agent reads skills.

1. Set up looot once

Give this line to your agent
set up looot - https://looot.ai/skill.md

Works in Claude Code, Cursor, Codex and ChatGPT through MCP. Searching and inspecting are free.

2. Save the skill

Save the skill file for Claude Code
mkdir -p ~/.claude/agent-skills/looot-find-phone-numbers && curl -fsSL https://looot.ai/agent-skills/find-phone-numbers/SKILL.md -o ~/.claude/agent-skills/looot-find-phone-numbers/SKILL.md

Or open the raw SKILL.md and drop it into the skills folder of your own agent.

When it starts

What do I say to start this skill?

Any of these starts it. The agent asks for what is missing, nothing more.

  • Example prompt
    find the mobile number for this LinkedIn profile

  • Example prompt
    get a phone number for Jane Doe at example.com

  • Example prompt
    what is the direct line for this person

It asks for

  • A LinkedIn profile URL, an email, or a name with a company domain

It hands back

  • Phone number
  • Line type
  • Country code and format
  • Carrier
  • Match confidence

Return the number, its line type and the match confidence. Say plainly when nothing matched instead of guessing.

How it runs

What does the agent do when it runs?

Four moves, in this order, with the price known before any money moves.

  1. Step 1

    Discover

    looot discover finds the endpoints that match the task. It is free.

  2. Step 2

    Inspect

    looot inspect shows the price and the exact input before anything is spent. It is free.

  3. Step 3

    Run

    looot run executes the call with an idempotency key, so a retry never charges twice. The agent reads the run status, not the HTTP code.

  4. Step 4

    Fall back

    On a provider error or a timeout the agent tries the next endpoint in the skill, cheapest first. It never retries a bad input elsewhere.

The file

What is inside the SKILL.md?

The whole file, as your agent reads it. No price is written in it: the agent reads the live price with looot inspect.

# Find a phone number

Phone number finder API for an agent: it sends a LinkedIn profile URL, an email, or a name and a company domain to a catalog endpoint and reads phone number, line type and country code back. Several providers sell the call, so the agent tries the cheapest first. You pay per call, and a failed call costs nothing.

This skill needs the looot skill set up first: https://looot.ai/skill.md

## Ask for these inputs

The job takes a LinkedIn profile URL, an email, or a name and a company domain. Example: https://www.linkedin.com/in/jane-doe-example.

- A LinkedIn profile URL, an email, or a name with a company domain

## Run it

1. Find the endpoint: `looot discover --mode auto --query "phone number finder"`. The endpoints listed below are the known matches.
2. Read the price and the input schema before spending: `looot inspect <endpoint-id>`. Tell the user the price, then run.
3. Run it: `looot run tomba-phone-finder --input '{"linkedin":"https://www.linkedin.com/in/jane-doe-example"}' --idempotency-key <new-key> --wait`. Reuse the same key only to retry the same request.
4. Read the run's `status` and `error`, not the HTTP status. A run can return `failed` with a normal response.
5. If a run fails with a provider error or times out, try the next endpoint from the list below, cheapest first. If it fails on your input (a 4xx style error), fix the input. Do not retry it on other providers.

## Endpoints

Each endpoint reads the same job from a different provider. They differ in inputs, fields and price. Run `looot inspect` on the ones that take the input you hold, start with the cheapest, and move to the next on a provider error.

- `tomba-phone-finder`: starts from an email, a LinkedIn URL or a domain, and returns international, local and E.164 formats with line type and carrier
- `ai-ark-people-mobile-phone-finder`: takes a LinkedIn URL, or a name with a domain, and returns null data when no person or no phone is found
- `leadmagic-people-mobile-finder`: takes a profile URL, a work email or a personal email and returns the mobile number
- `aviato-person-phone`: takes one identifier, such as an email, a LinkedIn URL or a Crunchbase id, and returns phone numbers with a score
- `findymail-api-search-phone`: takes a LinkedIn URL and returns the phone and its line type, with no result for EU citizens
- `lusha-contacts-phone-find`: takes a LinkedIn URL, an email, or a name with a domain, and is billed more when it finds a number than when it only matches the person
- `anysite-api-phones-find`: takes a LinkedIn URL and returns matches with a confidence level and how each was resolved

## What comes back

- Phone number
- Line type
- Country code and format
- Carrier
- Match confidence

## Answer rule

Return the number, its line type and the match confidence. Say plainly when nothing matched instead of guessing.

## Before you start

- Know the region you call. One provider here returns no result for EU citizens for legal reasons, and others hold thinner data outside the US.
- Respect do-not-call flags. One provider returns a doNotCall field, and your agent should keep it with the number.
- A number that is found is billed. A lookup that matches nobody is often free, but the rules differ per provider, so read the endpoint page for the exact charge.

## Cost rules

- Searching and inspecting are free. Running is billed per call at the price `looot inspect` shows.
- Say the price before the first run, and the total after a batch.
- Never loop a failing call. Stop after two failures and report what failed.

## When not to use this skill

Use `looot-enrich-a-person` instead when you need the title, employer and location around the number, not only the number.

Wrong fit

When should I use a different skill?

Use Enrich a person when you need the title, employer and location around the number, not only the number.

FAQ

What do people ask about this skill?

Send the profile URL to a phone-finder endpoint. Several providers here accept it. Use the vanity alias in the URL, not the numeric id. The answer is a number with a line type, or an empty result.
