# Usage Summary Csv

`GET /v1/usage/summary.csv`

Download every breakdown the summary reports, as one CSV.

One row per (dimension, key): model, user, API key, source, session
(``source_label``), endpoint, and provider. A dedicated route rather than a
``format=csv`` flag on ``/summary`` so that endpoint keeps a single JSON
response model and a clean OpenAPI schema. The export is **uncapped** (no
top-N fold): finance wants every row. ``tokens`` is the billed total (fresh
input, both cache buckets, and output), matching the dashboard's analytics.
Kept separate from the bare-array ``/v1/usage`` contract, which is untouched.

## Query parameters

- `start_date` string, date-time, nullable — Return logs with timestamp >= start_date (ISO 8601 or Unix epoch seconds)
- `end_date` string, date-time, nullable — Return logs with timestamp < end_date (ISO 8601 or Unix epoch seconds)
- `user_id` string[], nullable — Filter to one or more users; repeatable (user_id=a&user_id=b). Several values match any of them. At most 50 per call.
- `status` string, nullable — Filter to a single status: 'success', 'error', or 'absorbed' (an attempt a routing policy recovered from, excluded from error_count and request_count)
- `status_code` integer, nullable — Filter to a single failure status code (e.g. 429 for provider rate limits, 402 for missing-pricing rejections). Only error rows carry one, so this filter also restricts to status='error' unless 'status' is given explicitly
- `model` string[], nullable — Filter to one or more models; repeatable (model=a&model=b). Several values match any of them. At most 50 per call.
- `endpoint` string, nullable — Filter to a single endpoint (e.g. '/v1/chat/completions')
- `provider` string, nullable — Filter to a single provider (e.g. 'openai')
- `source` string, nullable — Filter to a single provenance source (e.g. 'gateway' or 'claude_code')
- `source_label` string, nullable — Filter to a single session/project label (the source_label carried by imported usage)
- `api_key_id` string[], nullable — Filter to one or more API key ids; repeatable (api_key_id=a&api_key_id=b). Several values match any of them. At most 50 per call.
- `priced` boolean, nullable — Filter by token-pricing state: true = only rows whose model tokens were priced, false = only rows that still need pricing (no cost at all, or tokens that were never metered because the model had no rate). A row charged only for gateway-run tool calls still counts as needing pricing.
- `tool` 'any' | 'web_search' | 'code_execution', nullable — Filter to requests that ran a gateway-run tool. 'any' matches any tool; a tool name (web_search, code_execution) matches that tool specifically.
- `counts_toward_budget` boolean, nullable — Filter by budget participation: true = only enforced gateway rows, false = only imported rows that never touch a budget
