Proof of Spend for AI agents
Dealroom mapped 112 agent-payment startups; 81 of 94 with a known date were founded in 2025–2026. Rails are crowded.
98% of FinOps teams track AI spend, but 73% still blow the budget; only 26% see it fully in real time.
BCG: 81% of US consumers expect to use agents when shopping, but only 4% would let an agent complete the purchase.
A dashboard shows spend. It does not prove the charge was correct.
Nidhipati verifies the payment path: mandate, amount, asset, network, payee, usage, refund, verdict. It is independent of the rail, the model vendor and the custodian.
- Agent and key that signed
- Mandate and policy
- Amount, asset, network, payee
- Transaction hash
- Usage and unit price
- Refund and remaining amount
- Policy verdict and reasons
- Replay / receipt ID
Not another dashboard
AI FinOps and LLM observability show what you spent. They do not prove the charge was correct, and they do not recover the difference. Nidhipati is a signed receipt and an independent audit — paid only when the finding is verified.
