ChatGPT guide

Enrich a company with ChatGPT

Turn a domain into a company profile: legal name, size, industry, headquarters, revenue band and social links.

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 enrich the company at [domain]. Run the job company.enrich with fallback on. Give me its legal name, founding year, employee count, industry, headquarters, revenue band and LinkedIn URL, and say which fields the provider did not return.

3. Jobs it calls and what they cost

company.enrich
1 call, from $0.00145 per result (Dropleads, the cheapest of 21 providers)
Compare providers About the cheapest provider

One use costs from $0.00145 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.

Good to know

Providers keep their own copy of company data. Read the sync date before you rely on a headcount.
