# Get tool context breakdown

`GET /v1/projects/{projectSlug}/tools/{toolName}/context`

Returns where the tool is used, broken down by a dimension: `model` and `provider` attribute the tool's traces via their chat spans; `tag` reads tags on the tool-call spans themselves.

## Path parameters

- `projectSlug` string, required — Project slug (human-readable identifier)
- `toolName` string, required — Tool name. URL-encode names containing special characters.

## Query parameters

- `fromIso` string, date-time — Lower bound (inclusive) of the time range. Defaults to 7 days before `toIso`.
- `toIso` string, date-time — Upper bound (inclusive) of the time range. Defaults to now.
- `dimension` 'model' | 'provider' | 'tag', required — Dimension to break the usage down by.
- `errorsOnly` 'true' | 'false' — When `true`, scope every aggregate to failed calls only.

## Response `200`
