Authenticate every request with an org-bound API key (created in Settings → API keys; Scale plan or free trial) sent as a bearer token: `Authorization: Bearer oak_…`. Compatibility: this is an early, fast-moving API. Most changes are additive (new endpoints, new optional params, new response fields, new enum/string values) — clients must tolerate unknown fields and unknown string values.
