How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
Returns a structured list of Form 144 notices for the requested ticker, including insider name, role/relationships, number of shares to be sold, approximate sale date, broker, exchange, aggregate market value, past 3-month sale history with proceeds, acquisitions history, shares outstanding, SEC EDGAR accession number and URL, and a count of parsed filings.
Example use cases
Insider selling alert before earnings
“Check if any executives or board members at Tesla have filed Form 144 notices recently — I want to know who's planning to sell shares, how many, and what they've sold in the last 3 months before the earnings report.”
Due diligence on new stock pick
“I'm considering buying into CrowdStrike — can you pull the latest SEC Form 144 insider sale filings for CRWD so I can see if any insiders are quietly planning to offload shares right now?”
Monitor insider activity across portfolio
“Look up recent Form 144 filings for Microsoft and Meta — I want to see which insiders are selling, their roles, the number of shares, and any sale history from the past quarter.”
