REST API

API reference

Everything your code or your agents can do with a workspace API key. Authenticate with a bearer token, and every request is scoped to the workspace that minted the key.

Authorization: Bearer dk_...openapi.json

Getting a key

Open the dashboard, go to API keys, and mint one. Keys are shown once and stored hashed, so copy it when it appears. Grant only the scopes that key needs: everything is deny by default.

Rate limits apply per key and per IP. A 429 response carries a retry-after header. Every response is JSON, and errors carry a machine-readable code alongside a human-readable message.
