Analytics API

The Analytics API lets you retrieve workspace metrics programmatically using the same data that powers the in-app analytics dashboards. All queries are scoped to the workspace identified by your API key.

For interactive endpoint documentation with request/response examples, see the API reference.

Authentication follows the same API key mechanism used across all v1 endpoints — refer to the API reference for details.

Endpoint

GET /v1/analytics/{metric}

Path parameter

Parameter	Type	Description
`metric`	string	The analytics metric to retrieve. See Available Metrics for all valid values.

Query parameters

Parameter	Type	Required	Description
`time_start`	ISO 8601 datetime	Yes	Start of the time range. Must include a timezone offset (e.g. `2026-01-01T00:00:00Z`). Must be before `time_end`.
`time_end`	ISO 8601 datetime	Yes	End of the time range. Must include a timezone offset.
`page`	integer	No	Page number for paginated metrics (1-based).
`page_size`	integer	No	Number of items per page for paginated metrics. Default: 50. Max: 200.

Time range resolution

The API automatically adjusts aggregation granularity based on the requested range:

More than 3 days → daily buckets
3 days or less → hourly buckets

Rate limits

5 requests per second per workspace.

Response format

All metrics return an AnalyticsResponse object with two fields:

Field	Type	Description
`type`	string	One of `simple`, `table`, `barchart`, `horizontal-barchart`, or `empty`
`value`	object	The metric data. Shape depends on `type` (see below).

`simple` — a single scalar value

{
  "type": "simple",
  "value": {
    "value": 1234,
    "prefix": null,
    "suffix": " runs"
  }
}

Field	Description
`value`	The numeric or string value
`prefix`	Optional string displayed before the value (e.g. `"$"`)
`suffix`	Optional string displayed after the value (e.g. `" runs"`)

`barchart` — time-series data

{
  "type": "barchart",
  "value": {
    "values": [
      { "name": "2026-01-15", "values": { "runs": 42 }, "value_mapping": null },
      { "name": "2026-01-16", "values": { "runs": 37 }, "value_mapping": null }
    ]
  }
}

Each item in values represents one time bucket. The keys inside values are metric-specific series names.

`table` — tabular summary

{
  "type": "table",
  "value": {
    "headings": ["Model", "Tokens", "Cost"],
    "rows": [
      { "Model": "gpt-4o", "Tokens": 50000, "Cost": 0.25 }
    ],
    "prefixes": { "Cost": "$" },
    "suffixes": null
  }
}

`horizontal-barchart` — ranked distribution

Same shape as table, displayed as a horizontal bar chart in the UI.

`empty`

Returned when there is no data for the requested time range.

Error responses

400 — invalid time range

{ "detail": "time_start must be before time_end" }

422 — validation error (e.g. page_size out of bounds)

{
  "detail": [
    {
      "loc": ["query", "page_size"],
      "msg": "ensure this value is less than or equal to 200",
      "type": "value_error.number.not_le"
    }
  ]
}

429 — rate limit exceeded

{ "detail": "Rate limit exceeded" }
