`POST /oauth/register`

Register a public OAuth client.

## Access

This operation does not declare a credential requirement in the released API contract.

Provider access, workspace membership, and agent grants are enforced separately. A token does not expand access to a repository or resource. [Set up developer access](/docs/build/developer-access).

## Request body

Required. Supported content types: `application/json`.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `client_name` | string | No |  |
| `redirect_uris` | array of string | No |  |
| `grant_types` | array of string | No |  |
| `response_types` | array of string | No |  |
| `scope` | string | No |  |
| `token_endpoint_auth_method` | `"none"` | No |  |

## Call the endpoint

Replace path placeholders and your credential. For body operations, create `request.json` using the required fields above; this command does not invent resource identifiers or consent.

```bash
curl --request POST \
  'https://commentary.dev/oauth/register' \
  --header 'Content-Type: application/json' \
  --data-binary @request.json
```

## Recover from errors

Use the returned status and error body. Correct invalid fields before retrying; reconnect or narrow the target for authentication and permission errors. For conditional writes, reload the latest version before preparing a new request. Respect rate-limit headers and retry only when the operation’s idempotency contract permits it.
