AlgoGP’s event-driven strategies already read SEC filings for free; adding an FMP key on the server lets the LLM read earnings call transcripts too, and selecting FMP as the data platform makes the local runners load its end-of-day prices.

Plans and limits

The free plan allows 250 requests per day and covers end-of-day prices and core statements for a limited universe; going over returns 429. Paid plans raise the limit per minute and add intraday data, more history, international listings and transcripts.
