Where to look
Usage (main navigation) has four views:
All charts respect the date range picker (today, 7 days, 30 days, 90 days, custom).
Drilling into a single request


The usage overview: totals for the window, and the daily shape of it


By model — where the credits actually went


By API key — find which integration is heaviest


By user — Studio-only, since an API call attributes to the key rather than the human


File storage, which is charged separately from inference
- Full timing: gateway in/out, provider in/out, total
- Token counts (
prompt_tokens,completion_tokens,total_tokens) - Credits used
- Whether a fallback fired and which model actually served the call
- Request ID — paste this into a support ticket and we find the trace instantly
Per-request cost in the response
Every API response includes these headers:credits_used field in the JSON response
body for most endpoints — not a header. The one exception is binary
responses with no JSON body to carry it (text-to-speech audio), which get an
x-credits-used header instead.
Streaming responses carry credits_used in the final SSE chunk instead of the body:
Exporting
CSV export: each panel (Daily, By model, By API key, By user) has its own CSV button that downloads that panel for the selected date range. API: the dashboard itself callsGET /workspaces/{workspaceId}/usage/{summary|daily|by-model|by-api-key|by-user|recent} (session-authenticated, from/to query params) — there is no /v1/usage endpoint for API keys today. For nightly ingestion into your own warehouse, pull from the CSV exports or the per-request data on your own logged responses.
Invoices
Billing → History lists every invoice — subscription renewals and topups. Each row links to:- A PDF invoice (UK VAT applied where required)
- The Stripe receipt
- The exact credit pack delivered
Reconciling with Stripe
Each Infery invoice references a Stripepi_... (payment intent) and in_... (invoice) id. If you reconcile via Stripe export, match on metadata.workspaceId — that’s the key Infery actually writes on checkout sessions; there is no infery_invoice_id metadata field.
