API keys
Send a Continuous API key on every/v1 operation:
403 auth_forbidden).
Create API keys in the app under Settings, then API keys. Key management has no public API.
See Errors for authentication failures and recovery.
Simulation tokens
Send a Simulation token to the Simulation’s data-planeendpoint:
/v1 route. Create and fork return a token once, valid for one hour; later reads omit it. Mint more with POST /v1/simulations/{id}/tokens (the generated token endpoint lists the ttl_seconds range); other unexpired tokens stay valid.
A missing or rejected token answers 401 auth_invalid with the response header X-Continuous-Simulation-Token-Rejected: true. A stopped Simulation answers 409 simulation_stopped before the token is checked.
See Send requests to a Simulation for the other data-plane responses.
