What is x402?

EXPLAINER$40.5M settled · 18 facilitators · 7 chains

x402 is an HTTP-native payment standard for machine-readable resource access. The flow uses HTTP 402 as the payment requirement: an agent requests a resource, receives payment instructions, signs a stablecoin payment, and retries with proof of payment.

Agent Economy tracks x402 through visible on-chain settlement activity. The page separates transaction count, USD settlement volume, facilitator share, and chain distribution so builders can see both usage scale and concentration.

The metric is useful because agent/API payment activity is measurable on-chain, but raw settlement activity should not be read as pure verified end-user commerce. Testing, infrastructure activity, and self-directed usage can be present in the totals.

How this data is tracked

METHODOLOGY

x402 data is pulled from public Dune dashboards and embedded into `public/data.json` by the daily GitHub Actions pipeline.

The route uses the same fields as the dashboard: `x402.totalTxs`, `x402.totalVolume`, `x402.protocols`, `x402.chains`, and daily/monthly trend arrays.

Caveat: raw on-chain settlement events can include tests, infrastructure activity, and repeated service calls. The page reports visible protocol activity, not audited organic commerce.

FAQ

JSON-LD
What does x402 transaction volume measure?+
It measures visible x402 on-chain settlement events in the Agent Economy dataset. The current build embeds 144,008,894 transactions from data.json.
How much x402 payment volume is tracked?+
The current x402 USD settlement field is $40,466,354, sourced from public Dune x402 dashboards and refreshed through the daily pipeline.
Which chains show x402 activity?+
The dataset currently tracks 7 x402 chains. The largest rows include Base, Solana, Polygon.
Is x402 the same as Tempo MPP?+
No. The x402 brief describes HTTP 402 per-resource payments, while the MPP brief frames Tempo MPP as a machine payment/channel style protocol. Agent Economy tracks both separately.
Does x402 volume equal verified organic commerce?+
No. The methodology notes treat raw on-chain activity as a market signal that can include testing, infrastructure traffic, and self-directed activity.
