# Query API Key Billing
## Request Headers
Enum: `application/json`
Bearer authentication format, for example: Bearer \{\{API Key}}.
## Query Parameters
Billing granularity. The maximum query range depends on the granularity you pick:
* `Hour` (up to 7 days per request)
* `Day` (up to 31 days per request)
* `Week` (up to 31 days per request)
* `Month` (up to 31 days per request)
Product type or business category. Common values: `llm`, `gen_api`, `web_search`.
Product name. Supports fuzzy matching.
Query start time, Unix timestamp in seconds (int64). Must be greater than or equal to `2026-01-01 00:00:00`.
Query end time, Unix timestamp in seconds (int64). Must be greater than `startTime`.
This endpoint only supports data after `2026-01-01 00:00:00`. It does not support pagination. The range between `startTime` and `endTime` must stay within the limit for the `cycleType` you request: 7 days for `Hour`, 31 days for `Day`, `Week`, and `Month`. To cover a longer period, split it into several requests.
**The query range limit is now enforced by the API.** It used to be applied only in the Novita console, so requests sent directly to this endpoint were never rejected for being too long. If your integration queries more than 31 days at once (or more than 7 days with `cycleType=Hour`), it now fails with HTTP `400` and a message in the form:
```text theme={"system"}
time range must not exceed 31 days for cycleType "Month"
```
The message always names the limit and the granularity that was rejected, so you can split the range and retry.
The API Key billing page in the Novita console offers only hourly and daily granularity. This endpoint still accepts all four values, so `Week` and `Month` remain available to API callers even though they are no longer offered in the console.
## Response Parameters
API Key bill list.
User account ID.
Bill start time, Unix timestamp in seconds. It marks the first second of the billing period. With `cycleType=Hour`, it is the top of that hour, for example `10:00:00`.
Bill end time, Unix timestamp in seconds. It marks the last second of the billing period. With `cycleType=Hour`, it is minute `59` and second `59` of the same hour, for example `10:59:59`.
Billing method: `1` (pay-as-you-go), `2` (subscription).
Product name.
Product type or subcategory.
API Key ID.
API Key name.
Masked API Key.
