ChatGPT guide

Find a work email with ChatGPT

Give the assistant a name and a company domain; it finds the work email through looot and says when no provider has one.

For humansFor agents

1. Connect looot to ChatGPT

Open ChatGPT Plugins at chatgpt.com/plugins.
Select the plus button, then "Add custom MCP server".
Enter a name (looot) and a short description, for example: live data APIs, paid per call.
Under Connection, choose Public endpoint and paste https://api.looot.ai/mcp, including the /mcp path.
Configure authentication, read the risk warning and select "I understand and want to continue".
Select "Create as a plugin", review the tools ChatGPT found on the server, then install the plugin.
looot's sign-in page opens when ChatGPT first needs your account: sign in and allow access. Runs are paid from your prepaid looot balance.

OpenAI's guide does not say which ChatGPT plans can add a custom MCP server. It says account and workspace policies apply to adding and using custom MCP servers.

2. Ask ChatGPT

Start a new conversation, type @ in the prompt box and select the looot plugin. Then paste the prompt.

Prompt

Use looot to find the work email of [first name] [last name] at [company domain]. Run the job people.email.find with fallback on. Tell me the email, the job title the provider returned and which provider found it. If every provider misses, say "not found" and do not guess an address.

3. Jobs it calls and what they cost

people.email.find
1 call, from $0.00483 per call (QuickEnrich, the cheapest of 17 providers)
Compare providers About the cheapest provider

One use costs from $0.00483 at today's cheapest providers. A provider that misses can fall back to the next one, which can cost more; looot charges only the calls that ran, from your prepaid balance.
