Everything these facilitators settle, to anyone, per UTC day. Listed services received $326,935 over the last 30 days: 17.0% of what the facilitators we measure settled over the same 30 days. That share is on the home page.

measured on-chain: settlement measured at least once. Attributed by settler address (tx.from in the settler set). Volume is USDC moved on-chain, measured per chain (1 USDC = $1). Data via Envio HyperSync (EVM) and Helius (Solana).
! a window that spans a day our ingest missed for that row, so it reads low: Vol 30d for OpenFacilitator on Base (missed 10-30); Vol 30d for Primer on Base (missed 10-13); Vol 7d and Vol 30d for Dexter on Solana (missed 10-24 to 10-25, 11-03 to 11-06, 11-10); Vol 30d for three.ws on Solana (missed through 10-20); Vol 7d and Vol 30d for Polygon Facilitator on Polygon (missed 10-13 to 11-05); and the 7 day total above.
Questions about these numbers
What does the measured on-chain mark mean?
What does the measured on-chain mark mean?
The mark shown next to a facilitator on this page means USDC settlement has been measured on-chain at least once for it, attributed by settler address: a transaction whose sender is one of that facilitator's known settler addresses. It is not a recency or activity signal, so it does not say the facilitator settled today, only that measured settlement has been read from the chain at some point. The mark is derived at read time from measured volume rather than stored, so a facilitator carries it as soon as any settlement is measured, and a facilitator with no measured volume shows no mark and stays listed, not measured.
Why do these figures differ from what a facilitator reports?
Why do these figures differ from what a facilitator reports?
Because nothing here is self-reported. Every figure is computed from blockchain transactions sent by that facilitator's known settler addresses, counting only the settler-sent legs of each transaction, so an escrow-style in-and-out pair is never counted twice. x402scan and the swader facilitator list are used only to discover which settler addresses are worth measuring; their amounts are used for logging and sanity checks, never as the source of a published number. The scope is also narrower than a facilitator's own dashboard: we count USDC settlement on the chains and settler addresses in our registry, so anything settled in another asset, on a chain we do not measure yet, or through an address we do not know about is not counted here.
What does the measurement window mean?
What does the measurement window mean?
The window selector switches between today (UTC), 7d, 30d and since Jan 2026. Each of them is a whole number of UTC day buckets, not a trailing span: the shortest is today so far, from 00:00 UTC to now, so it is not a trailing 24 hours and it resets at 00:00 UTC, and the multi-day windows are the preceding full UTC days plus today so far. The widest window (since Jan 2026) is the full extent of what we have measured, not the facilitator's own history. Each chain starts on its own date, and a window that spans an ingest gap reads low: those figures carry a ! mark. Switching the window re-sorts the table, so which facilitator sits first depends on which window is being read.
What if a facilitator is listed but has no measured volume?
What if a facilitator is listed but has no measured volume?
It means the facilitator is catalogued here but no USDC settlement has been read from its settler addresses on-chain yet, so it carries no on-chain mark. It is not a statement that the facilitator is inactive: it can equally mean we do not track its settler addresses, or do not measure its chain, yet. The mark is derived at read time from measured volume rather than stored, so it appears on its own as soon as any settlement is measured. A facilitator submitted by the community and not yet confirmed by an independent discovery source is labelled separately as community-submitted.
Where can I read this data as JSON?
Where can I read this data as JSON?
Every figure on this page is mirrored as machine-readable JSON. Facilitator volume is at /api/v1/facilitators, aggregate stats and the published uptime method at /api/v1/stats, and the full catalogue and data model at /llms-full.txt. The settler addresses on each facilitator page link straight to the block explorer, so the on-chain record can be checked without going through us.
x402 List is an independent directory. A facilitator verifies and submits x402 payments; a settler is an on-chain address used to settle them. This board compares measured USDC volume from tracked addresses across chains and time windows. Volume is a measured floor and does not establish service quality or successful delivery.
Central City has the highest 7d on-chain volume of the facilitators listed here, $567.4k. That is measured settlement moved by its settler addresses in that window, not a ranking of quality: it says nothing about how reliable, how priced or how well run the facilitator is.

$859.6k! settled in the last 7 days; 1,731,252! settlements in the last 7 days; 153 enabled settler EOAs across 41 listed facilitators. These totals and the 7 day figure above are a sum per facilitator, not deduplicated: a payment seen by two facilitators would count twice.
Vol today is today so far in UTC. Vol 7d and Vol 30d include today. Vol all covers since Jan 2026. Tx 7d counts settlements; Settlers counts enabled addresses. A ! marks incomplete ingest in that window, including its totals.
Definitions and limits
A facilitator verifies and submits x402 payments. A settler address originates the settlement transaction or pays its network fee. x402 List attributes volume to tracked settler addresses; it does not audit the facilitator business.
USDC amounts use 1 USDC = 1 USD. The figures are a measured floor over tracked addresses and chains. An on-chain mark records observed settlement, not service quality or delivery verification. Ingest gaps can understate volume.
Read times describe when the displayed source was read. Daily activity dates identify UTC buckets. The source does not publish a content-modified timestamp for these aggregates.
