Volume by primary chain a server lists in accepts[] · last 30d
Concentration heuristic — a wash-trading proxy
Across servers with ≥ 100 calls and ≥ 5 payers. Lower = broader payer distribution. Independent observers (Artemis) report ~50% of x402 transactions are wash trading; this metric is the proxy you can compute from public data.

A daily cron writes one immutable snapshot per UTC day to Vercel Blob. The chart needs at least two days to draw a line; meaningful divergence analysis takes ~7 days. Check back tomorrow.

What x402.be is and is not
Independent index of x402 servers and on-chain payment activity. Aggregates the public Bazaar APIs published by CDP and PayAI. Open data, neutral methodology.
6 chains observed across CDP + PayAI Bazaar. Shares reflect what facilitators advertise — independent observers report different breakdowns for actual on-chain settlement. See /methodology.
Browse the directory, hit /api/v1, or read the spec. No login, no rate limit, no tracking. Everything CC0 — copy and reuse.
What this measures: volume attributed to the first chain each server lists as accepted in its Bazaar entry. This is advertisement, not settlement — independent observers measuring actual on-chain USDC transfers report Solana with a higher share (49–65% per Linux Foundation / ETHNews, early 2026). Per-payment streams aren't exposed by Bazaar APIs today; when they are, this dashboard will reflect that finer-grained truth. See methodology.
Heuristic: calls/payer < 100 = verified; 100–999 = monitor; 1k–9.9k = concentrated; ≥ 10k = suspect. Bazaar APIs do not expose per-payer distributions, so this is a proxy, not a verdict — a suspectflag means “ask questions before quoting these volume figures”.
