# How to use ChatGPT to look up a startup's funding rounds with looot

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

## 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 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.

## Jobs it calls and what they cost

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.

- `company.funding`: 1 call, from $0.01 per call (PredictLeads, the cheapest of 3 providers). Compare providers: [company.funding benchmark](/benchmarks/company-funding). [About the cheapest provider](/providers/predictleads)

## A real run

- company.funding on predictleads-companies-financing-events (PredictLeads): answered, charged $0.01. Run id run_0762240bdea149f58a0dccbeddfa2d4d.

- Series D: $3.5 billion, September 2026, with Index Ventures among 3 linked investors. The same round appears a second time as EUR 3bn Series D Plus from another source.

## 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.
