Know exactly what your teams are spending on AI. Set budgets that actually enforce. Generate audit trails your finance team can trust.
Core capabilities
Hash-chained audit trail. Every request recorded. Tamper-proof.
Know exactly which team, service, and model drove every dollar.
Set hard limits. Get alerts before you overspend. Never surprise bills.
Who it's for
Your team makes hundreds of API calls daily. You need to know which service, which model, and what it cost — without digging through invoices.
AI spend is growing faster than your visibility into it. TOLVYN gives you an immutable audit trail and real-time budget controls — before the bill arrives.
You own the AI infrastructure. TOLVYN sits in the proxy layer — no SDK changes, no code refactors, full governance from day one.
TOLVYN works with any team using AI provider APIs (Anthropic, OpenAI, Google, and others). It is not designed for consumer chat interfaces.
Real-time visibility
A live feed of every API call — team, model, cost, and latency — the moment it lands.
How it works
Four steps from your first request to full financial visibility.
Point your AI SDK to the TOLVYN proxy endpoint. No code changes required.
Every request passes through TOLVYN. Captured, hashed, and forwarded instantly.
Costs linked to teams, services, and models automatically via metadata tags.
Set budgets, configure alerts, enforce limits — from a single dashboard.
No. TOLVYN only captures metadata — token counts, model used, cost, latency. Your prompt and response content never touches our storage.
Nothing. Our SDK is fail-open by design — if TOLVYN is unreachable, your AI calls route directly to the provider. Your business never stops because of us.
OpenAI shows your total bill. TOLVYN shows which team, which service, which feature caused it — with budgets that block spending before it happens and an audit trail that holds up to scrutiny.
Five minutes. Change one import line in Python or Node.js. Or set one environment variable. No YAML, no agents, no config files.
