# List browser extensions

`GET /extensions`

List extensions in the resolved project.

## Query parameters

- `limit` integer
- `offset` integer
- `query` string
- `name` string

## Response `200`

List of extensions

- Extension[]
  - `id` string, required — Unique identifier for the extension
  - `name` string, nullable — Optional, easier-to-reference name for the extension. Must be unique within the project.
  - `created_at` string, date-time, required — Timestamp when the extension was created
  - `size_bytes` integer, required — Size of the extension archive in bytes
  - `checksum` string, nullable — SHA-256 checksum, encoded as lowercase hexadecimal, of the exact uploaded extension archive bytes. This is not a normalized checksum of the extension contents; archive metadata, file ordering, and compression can change the checksum for otherwise identical contents. Omitted for legacy rows and server-repackaged Chrome Web Store extensions.
  - `last_used_at` string, date-time, nullable — Timestamp when the extension was last used

## Other responses
