ChatGPT guide

Search SEC filings with ChatGPT

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

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 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.

3. Jobs it calls and what they cost

sec.filings.search
1 call, from free (SEC EDGAR, the cheapest of 1 provider)
About the cheapest provider

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.
