FAQ

How current is the data? 13F filings are due 45 days after each quarter end, so holdings are up to about 135 days old.

Does it show short positions? No. 13F covers long positions in US-listed securities, plus options flagged by put/call.

Is this advice? No. It is a data tool built on public SEC filings.

Is it legal?

The actor reads public, open-licence or government data only and does not collect private information. You are responsible for using the results in line with the source's terms and applicable laws.

Use it with AI agents (MCP)

This actor is agent-ready: it is a plain tool with a documented JSON input and a flat JSON output, so Claude, ChatGPT, Cursor and other agents can call it through the Apify MCP server.

Calls are pay per event ($0.0005 per holding), so an agent can estimate the cost before it runs. Empty or failed lookups return a status record instead of failing the run.
