Errors, rate limits & plans

Error shape

Application errors return a consistent envelope:

{"error": {"message": "Invalid email or password", "details": {}}}

Common statuses: 400 validation, 401 not authenticated, 403 not authorised, 404 not found, 409 conflict (e.g. email already exists), 429 rate-limited.

Rate limits

auth               5/minute    login, register
auth_sensitive     3/minute    password reset, email verification
secrets           20/minute    writing BYO LLM keys / integrations
api              100/minute    general endpoints
api_heavy         30/minute    analytics, exports
websocket         10/minute    connection attempts

Free vs Pro

Free: agents, sequential workflows, community templates, live logs and run history. Pro ($29/mo): every orchestration mode (parallel, conditional, fan-out, loop, DAG), advanced analytics, and publishing your own templates.

The Pro gate applies to scheduled and webhook runs too — a non-sequential workflow on a schedule is skipped if the owner is not entitled.
