APV is the canonical on-chain metric for AI agent payment activity — the TVL equivalent for agentic commerce. Tracks USDC volume settled by AI agent payment protocols over a rolling 30-day window.
Weekly agent payment volume since tracking began. x402 data via Dune; ACP v2 launched March 26, 2026.
APV measures the total value of payments settled by AI agents through on-chain payment protocols in a given period. It is the closest equivalent to DeFi's Total Value Locked (TVL) for the emerging agent payments layer — a single number that captures the real economic activity flowing through agent-native payment infrastructure.
APV is not a price or market cap metric. It tracks actual payment flow: USDC moving between agents and services in exchange for compute, data, and work completed. A higher APV means more agents are transacting, more services are being consumed, and the machine-to-machine economy is growing.
APV currently aggregates two protocols with meaningful on-chain USDC volume:
| Protocol | Contract | Chain | Data source | Status |
|---|---|---|---|---|
| x402 | 0x402085c2...20001 | Base | Dune Analytics (query 5236154) | live |
| Virtuals ACP v1 | 0x6a1FE26D...0A4A | Base | Blockscout token transfers | live |
| Virtuals ACP v2 | 0xa6C9BA86...9df0 | Base | Blockscout token transfers | live |
We track USDC inflows only — payments entering the protocol — to avoid double-counting escrow settlement. x402 volume comes from the Dune weekly aggregation query; ACP volume is computed by paginating USDC token transfers to the v1 and v2 contract addresses.
The following protocols have on-chain components but are not yet included in APV:
APV data is refreshed daily at 6am PT via a scheduled GitHub Actions job. The figure shown reflects the most recent daily snapshot. The 30-day window rolls forward each day.
