API keys and rate limits

The ARBK REST API exposes search, autocomplete, and individual business endpoints under /api/v1. Access requires an API key, which is available on the Enterprise plan.

Generate keys from Account → API Keys. Keep them secret; treat them like passwords. Each key has its own daily quota and usage counter that resets at midnight UTC.

Authenticate by sending the key in the Authorization header as a Bearer token. Responses are JSON with stable field names matching the database schema.

For schema details, query parameters, and example responses, see the docs page at /docs. We version the API and announce breaking changes well in advance.
