# What Claude Code was used for, by kind of activity

> Activity is what Claude Code and Cowork reported about themselves, kept as daily totals: names, counts and durations, never the text of a prompt, a response or a command. sections has one entry per kind of activity over the range, with its largest rows. response_times estimates, per model, how long a request took and how long its first token took: the times are kept in buckets, so each figure can be off by the width of one. people says how many people each kind of activity reached, and names nobody.

## GET /api/v1/providers/anthropic/activity

Activity is what Claude Code and Cowork reported about themselves, kept as daily totals: names, counts and durations, never the text of a prompt, a response or a command. sections has one entry per kind of activity over the range, with its largest rows. response_times estimates, per model, how long a request took and how long its first token took: the times are kept in buckets, so each figure can be off by the width of one. people says how many people each kind of activity reached, and names nobody.

### Authentication

Send `Authorization: Bearer <token>`.

### Parameters

- `start` (query, string, required): First day, ISO 8601 (YYYY-MM-DD or a datetime)
- `end` (query, string, required): Last day, ISO 8601 (YYYY-MM-DD or a datetime), included

### Responses

#### 200: Successful Response

- `success` (boolean, default `true`)
- `data` (object, required)
  - `sections` (array of object, required): One entry per measure, in a fixed order, including a measure nothing was counted for
    - `events` (integer, required): How often it happened. For active_time and lines it is the number of reports received, each covering some seconds or lines: read their amount
    - `amount` (number, required): What the measure adds up besides a count: milliseconds for tool and mcp_connected, seconds for active_time, characters for prompt, lines for lines, USD of usage value for request_source and repository, and 0 for a measure that only counts
    - `measure` (string, required): The kind of activity, such as tool, plugin or session
    - `items` (array of object, required): The 200 largest rows of the measure, largest first: by amount for request_source and repository, by events for every other measure
      - `events` (integer, required): How often it happened. For active_time and lines it is the number of reports received, each covering some seconds or lines: read their amount
      - `amount` (number, required): What the measure adds up besides a count: milliseconds for tool and mcp_connected, seconds for active_time, characters for prompt, lines for lines, USD of usage value for request_source and repository, and 0 for a measure that only counts
      - `key` (string, required): What was counted, such as a tool, a plugin or a language
      - `detail` (string, required): What tells rows of one key apart, such as an outcome or a version
    - `more` (object, required): Every row past the 200 listed, added up
      - `events` (integer, required): How often it happened. For active_time and lines it is the number of reports received, each covering some seconds or lines: read their amount
      - `amount` (number, required): What the measure adds up besides a count: milliseconds for tool and mcp_connected, seconds for active_time, characters for prompt, lines for lines, USD of usage value for request_source and repository, and 0 for a measure that only counts
  - `response_times` (array of object, required): One entry per model that was timed, the model with the most requests first, at most 50
    - `model` (string, required): The model, or (other) for times the intake could not keep under a model
    - `requests` (integer, required): Requests that said how long they took
    - `first_token_p50_ms` (integer, nullable, required): Estimated median time to the first token, in ms. Null when no request said it, as with requests that were not streamed
    - `first_token_p90_ms` (integer, nullable, required): Estimated time to the first token that 9 in 10 requests stayed under, in ms. Null as the median is
    - `total_p50_ms` (integer, nullable, required): Estimated median time of a whole request, in ms. Null for the model (other)
    - `total_p90_ms` (integer, nullable, required): Estimated time of a whole request that 9 in 10 requests stayed under, in ms. Null as the median is
  - `people` (object, required): How many people each kind of activity reached, each person counted once
    - `sessions` (integer, required): People who started a session
    - `active_time` (integer, required): People with active time
    - `prompts` (integer, required): People who sent a prompt
    - `api_errors` (integer, required): People who had a model request fail
    - `lines` (integer, required): People for whom Claude Code added or removed lines of code
    - `git_output` (integer, required): People for whom Claude Code made a commit or opened a pull request
- `timestamp` (string, required)
