TokenGauge v0.3.0 turns provider-level token totals into a practical application-attribution workflow.
Start free
- Audit an AI API bill locally in the browser.
- Attribute cost by project and workflow with the canonical CSV ledger.
- Read the LLM cost-per-customer and feature guide.
The guide separates the provider ledger from application context, recommends opaque customer labels instead of personal data, accounts for cache buckets and retries, compares cost per accepted answer, and keeps modeled token cost distinct from the provider invoice.
Fixed-scope implementation
The £75 attribution setup covers one authorized Node.js/TypeScript or Python codebase and one existing provider path: project/workflow labels, retry-aware usage fields, a TokenGauge-compatible CSV export, focused tests, handoff notes, and one revision after written scope.
No credentials or private source belong in the initial enquiry. No savings are guaranteed, and API credits are not included.
Existing workbench
- 52 dated pricing cards across nine provider families
- 120 evidence cards, including 12 open cards
- 1,316 atomic research candidates and 1,184 compound configurations—2,500 research rows, not 2,500 distinct proven methods
- verified-email and ChatGPT-linked accounts, TOTP 2FA, encrypted provider connections, Stripe Checkout, dashboard, and controlled A/B lab
Validation
The release passed atlas freshness verification, ESLint, strict TypeScript, 44 Vitest tests, a 31-route Next.js production build, responsive 390px and 1440px browser checks, live canonical/sitemap/schema checks, and credential-pattern scanning. The live mirror and maintained application are independent of any listed model provider.
