Overview
What AgentAudit does
AgentAudit answers what AI agents are buying with x402 payments, from on-chain data.
- GET /v1/stats returns totals: settlements, USD volume, average price, unique buyers, active and tracked sellers.
- GET /v1/trending?period=7d ranks x402 services by settlement volume over 24h, 7d, 30d, 90d or all time.
- GET /v1/flow?limit=10 returns the latest settlements, newest first.
- GET /v1/discover?category=data recommends services in a category, ranked by real settlement activity.
- GET /v1/seller/{address} and GET /v1/buyer/{address} return one seller's settlement history or one buyer's spend by seller.
- POST /v1/receipt verifies 1-20 Base transaction hashes as x402 settlements and totals the spend by service.
Where the data comes from
Every USDC transferWithAuthorization (EIP-3009) on Base into a wallet that a CDP Bazaar (agentic.market) listing names as its payTo, matched to the payer's AuthorizationUsed log in the same transaction, indexed from May 12 2026. The index and leaderboards refresh daily at 00:15 UTC and every response says indexed_through. Plain USDC transfers are excluded and Solana is not indexed.
Three ways to connect
- REST with an X-API-Key header, described by an OpenAPI 3 schema (https://agentaudit.waltsoft.net/openapi.json ).
- MCP: the tools agentaudit___getStats, getTrending, getFlow, discoverServices, getSeller, getBuyer and verifyReceipts on the Amazon Bedrock AgentCore Gateway, for Claude, Strands Agents and other MCP clients.
- A2A (Agent2Agent 0.3): the agent card at https://agentaudit.waltsoft.net/.well-known/agent-card.json with one skill per operation.
Who it is for
Teams building or selling x402 services who need market data, agent developers choosing which paid services to call, finance and audit workflows that must confirm a payment was an x402 settlement, and analysts tracking agent commerce.
Billing
You pay per successful call on your AWS bill. Errors (400, 401, 404, 429, 5xx) are never billed. Rate limit: 50 requests per second, bursts up to 100.
Highlights
- x402 market data from on-chain settlements: totals, trending services over 24h to all time, and the latest settlements on Base, refreshed daily
