P402.io

Meter, attribute, and govern every AI request — with optional x402 crypto settlement on Base.

Event-level AI cost ledger

Every AI request becomes a record with owner, workflow, model, provider, token count, cost, budget state, policy result, and evidence status — so spend is attributed at the moment it happens instead of after the invoice arrives.

Metadata-only privacy modes

Prompts, responses, and raw traces are rejected at the API boundary by default. Five privacy modes scale from metadata-only up to explicit full-trace opt-in for teams that need deeper debugging.

OpenAI-compatible routing

Point your existing OpenAI-style code at a new base URL and P402 routes each call to the best cost/speed/quality model, with a full audit trail and semantic caching available.

x402 micropayments and USDC settlement

Optional payment rail implementing HTTP 402 flows with gasless USDC on Base mainnet via EIP-3009, 3-of-5 multisig treasury controls, and a global edge verification network.

Strengths & Pros

+Attributes AI cost to the exact owner, feature, and workflow while the request is still fresh
+Metadata-only default with no prompt storage removes a major compliance objection
+Drop-in OpenAI-compatible API means migration requires only a base URL and key change
