What does this dashboard show?

Real agent-payment volume across x402, ACP, AP2 and MPP — with x402 measured on-chain on Base and other protocols shown at their self-reported (claimed) values.

What is 'real' volume?

Nominal volume counts every settlement, including sub-cent machine loops concentrated on a few wallets. Real volume filters those out to approximate organic agent commerce.

Where does the data come from?

x402 data is indexed on-chain from Base via the Coinbase CDP SQL API, cross-checked against Dune. Non-x402 protocols publish no verifiable call data, so their figures are self-reported.

The Agent Economy, Measured

Real agent-payment volume across x402, ACP, AP2 and MPP — nominal numbers cleaned of wash and idle machine traffic. Verifiable on-chain data separated from claimed values.

Real vs nominal volume

Nominal counts every settlement. Real strips single-buyer, sub-cent machine loops that inflate the headline — the gap is the story.

Cross-protocol comparison

x402 is measured on-chain. Other protocols publish no verifiable call data — their figures are self-reported and labeled as claimed.

How we measure real volume

A seller is flagged as machine noise when its average transaction is under $0.02 and its transactions are concentrated on very few buyers. Real GMV excludes those sellers. Thresholds are transparent and tunable — the point is to show organic agent commerce, not inflated micro-loops.

Sources: x402 on-chain via the Coinbase CDP SQL API (Base). ACP / AP2 / MPP / AP4M figures are self-reported by each protocol. Cross-checked against Dune.
