Authorizations

​
Authorization
string
header
required

Basic authentication header of the form Basic <encoded-value>, where <encoded-value> is the base64-encoded string username:password.

Body

application/json

Request to compute per-call usage for a trace, with descendant rollup.

This endpoint returns usage metrics for each call in the trace, where each call's metrics include the sum of its own usage plus all descendants' usage. Use this for trace view where you want to see rolled-up metrics per call.

Note: All matching calls are loaded into memory for aggregation. For very large result sets (>10k calls), consider using more specific filters or pagination at the application layer.

​
project_id
string
required
​
filter
CallsFilter · object

Filter to select calls. Typically use trace_ids to get all calls in a trace.

​
query
Query · object

Additional query conditions for filtering calls.

​
include_costs
boolean
default:false

If true, include cost calculations in the usage.

​
limit
integer
default:10000

Maximum number of calls to process. Acts as a safety limit to prevent unbounded memory usage.

Response

Successful Response

Response with per-call usage metrics (each includes descendant contributions).
