Exports aggregated spend for a period as CSV, grouped by the dimension your finance process needs. group_by is a strict allowlist and a tag key is bound as a query parameter, so there is no injection surface. Every row carries unpriced_requests alongside cost_usd, so a pricing gap is visible in the export rather than hidden inside a total. A model that is not in the pricebook is recorded with cost_source = 'unpriced' — never booked as free.

Cells are quoted and formula-neutralized. Every cell is quoted, and any cell beginning =, +, - or @ is prefixed with a single quote, so a model name or a tag cannot execute as a formula when someone opens the file in a spreadsheet. If you parse this file, parse it as real CSV — do not split on commas.

For the same data as JSON, use Usage & cost. Requires the read capability on ai_gateway. See the control-plane overview for authentication, the {data, meta} envelope, pagination and error types.

Authorizations

Authorization

string

header

required

OAuth 2.1 authentication — recommended for new integrations. Access tokens (kc_ prefix) are minted at the root-host token endpoint https://api.knoxcall.com/oauth/token and passed as Authorization: Bearer <access_token>. Public clients must use PKCE with the authorization_code grant; confidential clients may use client_credentials. The first-party SDKs and the knoxcall login CLI handle token minting, caching, refresh, and DPoP for you.
