Authentication

One key, three ways in: REST header, RapidAPI proxy, or MCP bearer token.

API keys

Keys look like edgr_.... Create and revoke them in your dashboard. Send your key on every request in the X-API-Key header:

curl https://api.edgrapi.com/v1/company/AAPL -H "X-API-Key: edgr_..."

Treat keys like passwords. If one leaks, revoke it in the dashboard and create a new one; revocation takes effect immediately.

Via RapidAPI

Subscribe through RapidAPI and their proxy authenticates you, so you don't need an Edgrapi key. RapidAPI meters your plan and forwards verified requests to the origin.

Via MCP & agents

The hosted MCP server and the agent skill use the same key as a bearer token:

Authorization: Bearer edgr_...
