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 for aggregated call statistics over a time range.

​
project_id
string
required
​
start
string<date-time>
required

Inclusive start time (UTC, ISO 8601).

​
end
string<date-time> | null

Exclusive end time (UTC, ISO 8601). Defaults to now if omitted.

​
granularity
integer | null

Bucket size in seconds (e.g., 3600 for 1 hour). If omitted, auto-selected based on time range. Will be adjusted if it would produce more than 10,000 buckets.

​
usage_metrics
UsageMetricSpec · object[] | null

Usage metrics (tokens, cost) to compute. Grouped by timestamp and model.

​
call_metrics
CallMetricSpec · object[] | null

Call-level metrics (latency, counts) to compute. Grouped by timestamp only.

​
filter
CallsFilter · object
​
timezone
string
default:UTC

IANA timezone for bucket alignment (e.g., 'America/New_York')

Response

Successful Response

Response containing time-series call statistics.

​
start
string<date-time>
required

Resolved start time (UTC)

​
end
string<date-time>
required

Resolved end time (UTC)

​
granularity
integer
required

Bucket size used (in seconds)

​
timezone
string
required

Timezone used for bucket alignment

​
usage_buckets
Usage Buckets · object[]

Usage metrics by model. Each bucket contains 'timestamp', 'model', and aggregated metric values.

​
call_buckets
Call Buckets · object[]

Call-level metrics. Each bucket contains 'timestamp' and aggregated metric values.
