Insider Trading APIs

Q: Is there a free Insider Trading API?

Yes. Earnings Feed, XOOMAR, AlphAI and FinBridge have a free tier alongside paid plans. See all free Stock APIs.

Q: Which Insider Trading APIs work without an API key?

All of them need a key or account. Earnings Feed, XOOMAR, AlphAI and FinBridge give one out free when you sign up.

Q: Can I use Insider Trading APIs in a commercial project?

Earnings Feed permits commercial use. SEC-API Insider Trading, AlphAI and FinBridge restrict it, for example to non-commercial or attributed use, so read the terms first.

Q: Which Insider Trading APIs work with AI agents?

Earnings Feed, XOOMAR and FinBridge have an MCP server, so an AI agent can call them directly. AlphAI publishes an OpenAPI spec for generating clients and tools.

Insider trading data comes from SEC Forms 3, 4 and 5, and these APIs package it differently. SEC-API Insider Trading is a paid service that indexes those forms as searchable JSON seconds after filing. Earnings Feed and XOOMAR include insider trades within broader filing feeds, FinBridge adds Korean DART disclosures, and AlphAI attaches insider activity to ticker-level news. Free Stock APIs →
