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 aggregated usage for multiple root calls.

This endpoint returns usage metrics for each requested root call, where each root's metrics include the sum of its own usage plus all descendants' usage.

Note: All matching calls are loaded into memory for aggregation. For very large result sets (>10k calls), consider batching root call IDs or using narrower filters at the application layer.

​
project_id
string
required
​
call_ids
string[]
required

Root call IDs to aggregate. Each result key corresponds to one input call ID.

​
include_costs
boolean
default:false

If true, include cost calculations in the usage.

​
limit
integer
default:10000

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

Response

Successful Response
