> **This method is not served on the public API.** `api.sylphx.com` does not route this call: its backend is not deployed behind the public API, or does not implement the call. This page documents the contract. It is kept out of the sidebar and of search engines.

Lists services in a environment.

**Not available yet.** Sylphx Hosting is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

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