ChatGPT guide

Look up funding rounds with ChatGPT

List a company's funding rounds with amounts, dates, investors and the articles they came from.

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 list the funding rounds of [company domain] with the job company.funding, fallback on. Return a table with date, round type, amount and investors, newest first. Merge rows that describe the same round from different sources, and link one source per round.

3. Jobs it calls and what they cost

company.funding
1 call, from $0.01 per call (PredictLeads, the cheapest of 3 providers)
Compare providers About the cheapest provider

One use costs from $0.01 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

Funding data is collected from news articles, so one round can appear twice under two names. Merge before you add up totals.
