`GET /v1/organizations/{orgId}/projects/{projectId}/obs/services`

The services obs discovered from the telemetry the project sends: one per service key (service.namespace/service.name, or service.name), with the environments, signals, applications and languages each was seen with, but not its versions. Read-only: a service is created when ingest first sees its key and disappears once all its data has aged out. capReached says the project is at obs.services.perProject, so new keys aren't cataloged. 404 while the service catalog isn't offered yet (the console hides Services then).

## Authentication

Requires one of the following:

- `apiKey`, http, header `Authorization`
- `oauth`, http, header `Authorization`
- `sessionCookie`, apiKey, in cookie

## Path parameters

- `ListServices.path.orgId` (string, required)
  - format `uuid`
- `ListServices.path.projectId` (string, required)
  - format `uuid`

## Query parameters

- `ListServices.query.limit` (integer, optional) — The page size. Out of range is 400, never a clamp.
  - min 1; max 100; default `20`
- `ListServices.query.cursor` (string, optional) — The previous page's nextCursor. Bound to the organization, the list and its filters.
- `ListServices.query.q` (string, optional) — Only services whose key or name contains this, ignoring case (1-255 bytes).
  - minLength 1; maxLength 255
- `ListServices.query.key` (string, optional) — Only the service with exactly this key.
  - minLength 1; maxLength 255
- `ListServices.query.environment` (string, optional) — Only services seen in this environment.
  - pattern `^[a-z0-9][a-z0-9._-]{0,62}$`
- `ListServices.query.application` (string, optional) — Only services seen with this application (ezgh.metadata.application).
  - pattern `^[a-z0-9][a-z0-9._-]{0,62}$`
- `ListServices.query.active` (string, optional) — true: seen in the last 7 days; false: not; all: both.
  - one of `"true"`, `"false"`, `"all"`; default `"true"`
