Server: `https://api.inth.com`

Operation ID: `createOrganization`

## Authentication

* bearerAuth

### Schemes

* bearerAuth: http / bearer - Use an Inth API key or OAuth access token in the Authorization header.

  Every operation needs a capability. An OAuth access token carries the capabilities it was granted as scopes; an organization API key carries a fixed set (\`organizations.read\`, \`projects.read\`, \`projects.write\`, \`api-keys.read\`). A credential without the capability an operation needs is answered with \`403 INSUFFICIENT\_SCOPE\`. \`GET /v1/me\` reports the capabilities of the calling credential.

  OAuth scopes:
  - \`organizations.read\`: List the organizations you belong to.
  - \`organizations.write\`: Create organizations you will own.
  - \`projects.read\`: Read projects and their consent configuration.
  - \`projects.write\`: Create, update, and delete projects and their consent configuration.
  - \`members.read\`: List organization members and pending invitations.
  - \`members.write\`: Change member roles and remove members.
  - \`api-keys.read\`: List organization API keys.
  - \`api-keys.write\`: Create, roll, and delete organization API keys.

### 403

The credential is valid but may not perform the operation.

\`INSUFFICIENT\_SCOPE\`: the credential was never granted the capability the operation needs. \`details.requiredScope\` names it, and the \`WWW-Authenticate\` header carries \`Bearer error="insufficient\_scope"\`. An OAuth client fixes this by requesting the scope; an organization API key cannot gain it.

\`FORBIDDEN\`: the capability is present but the membership behind the credential lacks the role, or the resource belongs to another organization.
