The cf0 REST API lets you build integrations on top of cf0’s financial research platform. You can stream AI research sessions, retrieve generated reports, search global SEC and regulatory filings, manage uploaded documents, and create or invoke reusable research workflow skills.

​
Base URL

All endpoints are served from: 
https://api.cf0.ai

​
Request format

Send JSON bodies with Content-Type: application/json. File upload endpoints use multipart/form-data — see Documents API for details.

​
Response format

All endpoints return JSON. The chat endpoint (POST /api/lab/chat) returns a Server-Sent Events stream with Content-Type: text/event-stream. The filings ingestion progress endpoint (GET /api/filings/ingest/stream) also streams SSE.

​
Authentication

Every request requires a Bearer token in the Authorization header: 
Authorization: Bearer <your-token>
See Authentication for how to obtain and use your token.

​
Error responses

Error responses follow a consistent shape: 
{
  "detail": "Human-readable error description"
}
Common HTTP status codes:
CodeMeaning
400Bad request — missing or invalid parameters
401Unauthorized — missing or invalid token
403Forbidden — valid token but insufficient permissions (e.g. org required)
