Lists pools in a environment.

- **Path** `GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/pools`
- **Scope** `sandboxes:read`
- **Effect** `read` — nothing is written.
- **Collection** [pools](/docs/api/pools)
- **Query** `page_size`, `page_token`, `filter`, `order_by`
- **Pagination** the answer carries `pools` and, when there is more, `next_page_token`
