The Data City v2 API uses Bearer-token authentication. Every request must send an Authorization header.

​
Request format

Tokens are sent as plain HTTP Bearer credentials — no signing, no rotation header, no expiry parameter on the request itself.
Treat your API key like a password. Never check it into source control, ship it in a frontend bundle, or paste it into a shared chat. Store it as an environment variable or in a secrets manager.

​
Getting a key

API keys are issued manually by The Data City. To request one, email support@thedatacity.com with:
  • The name of your organisation.
  • The email address of the person who will hold the key.
  • A short description of what you intend to use the API for.
A member of the team will provision the key and reply with the value.

​
Replacing a key

If a key is leaked, lost, or you want to rotate it, email support@thedatacity.com and ask for a replacement. The old key will be disabled.

​
Failure modes

See Errors for the full envelope and other status codes.

​
Abilities

Each token is scoped to one or more abilities (for example companies:read, rtic:read, companies:companyDetails). The endpoints you can call are the intersection of what your token allows and what the route requires. If a request returns 403 despite a valid token, the missing piece is an ability — contact support to widen the scope.

​
Admin routes

A small number of /admin/... routes use a different X-API-Key header for internal use only. These are filtered out of the public reference and are not callable with a customer Bearer token.
