Usage by API key
⚠️
Preview — this feature is being built; the design below is the spec.
GET https://app.syntic.ai/v1/organizations/analytics/api_keysRequests, tokens and spend per API key and service account for a period, sorted by spend. Keys that made no requests are left out unless include_idle=true, which is how you find keys to retire.
For how this fits into a full workflow, see Usage analytics.
