Introduction

The interactive Try it panel in the API reference requires a running Friday daemon on your machine. All requests go to http://localhost:18080 — make sure Friday Studio is running before testing endpoints.

Quick examples

Check if the daemon is running:

curl http://localhost:18080/health

List all spaces:

curl http://localhost:18080/api/workspaces

Send a prompt to a space:

curl -X POST http://localhost:18080/api/workspaces/{workspaceId}/chat \
  -H 'Content-Type: application/json' \
  -d '{
    "id": "chat-001",
    "message": {
      "role": "user",
      "content": "What can you help me with?"
    }
  }'

Trigger a signal:

curl -X POST http://localhost:18080/api/workspaces/{workspaceId}/signals/{signalId} \
  -H 'Content-Type: application/json' \
  -d '{"payload": {"key": "value"}}'

List available agents:

curl http://localhost:18080/api/agents
