Session metrics
Volumes, completion and feedback rates over the scenario’s sessions.
404 when the scenario has produced no sessions yet — an empty scenario has no metrics, which is different from metrics that are all zero.
Authorizations
MCPJam API key (sk_…). Create one at Settings → API keys. Guest sessions cannot use the API, and API keys cannot manage other API keys.
Path Parameters
ID of the hosted project that contains the server.
Scenario ID, as returned by publishing an environment or by the project's scenario reads.
Query Parameters
Restrict to real visitors or synthetic (swarm-driven) sessions. Omit for both. Any other value is a 400.
real, synthetic Response
The metrics.
Session metrics for the scenario: volumes, completion and feedback rates, cohort splits.
Deliberately UNPINNED. The upstream projection grows with the product and the SDK types it as an open record for the same reason — pinning a field list here would turn every added metric into a spec violation. Read what you recognize and ignore the rest.
