Check whether a project has spans
Returns whether the project has at least one span matching the given scope. Cheap existence probe (LIMIT 1) used to drive empty-state decisions without scanning or aggregating the whole project.
Query parameters
project_id
project_name
source
Restrict the probe to a single ingestion source (e.g. 'sdk' for the Logs empty state), matching the rendered list's logs-source scope. Omit to probe any source.
Response
