# How to use ChatGPT to search SEC filings with looot

Find every 10-K or 10-Q that mentions a phrase, with the company, form and filing date. SEC EDGAR is free.

## Connect looot to ChatGPT

1. Open ChatGPT Plugins at chatgpt.com/plugins.
2. Select the plus button, then "Add custom MCP server".
3. Enter a name (looot) and a short description, for example: live data APIs, paid per call.
4. Under Connection, choose Public endpoint and paste https://api.looot.ai/mcp, including the /mcp path.
5. Configure authentication, read the risk warning and select "I understand and want to continue".
6. Select "Create as a plugin", review the tools ChatGPT found on the server, then install the plugin.
7. 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.

## Ask ChatGPT

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

Use looot to search SEC filings for the phrase "[phrase]" with the job sec.filings.search. Keep forms [10-K, 10-Q] filed from [start date] to [end date]. Tell me how many filings match, which companies mention it most, and list the five most relevant with company, form and filing date.

## Jobs it calls and what they cost

One use costs from free 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.

- `sec.filings.search`: 1 call, from free (SEC EDGAR, the cheapest of 1 provider). [About the cheapest provider](/providers/edgar)
