Observability

List traces

A project's traces, newest first: each its root span's name, start_us, duration_us, span_count, error_count, the services it crossed and its HTTP status.

GET/workspaces/{workspace}/projects/{project}/observability/traces

Filter by words in q, errors_only, min_duration_ms, environment and service, between from and to. A page holds limit; pass next back as cursor for the next. Needs a role on the project’s repository.

Each trace is its root span (or its earliest, when the root has not arrived), with what the rest add up to.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: observability with action traces, and the same inputs
Scope: An access token needs observability:read.

Status	Code	When
401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change, or a token without the scope it needs.
404	`not_found`	It does not exist, or you cannot see it.
422	`invalid`	The input is not valid. `message` says which field and why.
