State of x402 · Q2 2026

A dated, citable snapshot of the slice of x402 that x402 List measured in Q2 2026 (2026-04-01 to 2026-06-30), reconstructed from the monitoring archive, not a census of the whole ecosystem. Figures cover the full calendar quarter; they do not change.

⚠ Corrected 2026-07-03: category normalization, a case-variant "data" row was folded into "Data" (8 → 7 categories). No uptime or volume figures were affected.

⚠ Corrected 2026-08-17: on-chain settlement figures. This period was first published from the monthly volume rollup, which is rebuilt incrementally over a trailing window, so months whose daily rows were backfilled later had no monthly bucket and were missing from the totals. Settlement volume and settlement count are now summed from the daily snapshots, which cover the period in full. Previously published: $3.34M volume across 19,611,577 settlements. Services monitored, weighted uptime, the per-category split and the active facilitator count are identical on both grains and did not change.

⚠ Corrected 2026-08-17: monthly volume rollups rebuilt from the full daily history. The rollup passes only re-aggregated a trailing 45-day window, so a bucket whose daily rows arrived later was never built: the April and May Polygon backfill fell outside it, as did later Base and Solana tails. A nightly full-history pass now rebuilds every bucket since inception. Settlement volume for this quarter moves from $3.34M to $3.65M and settlements from 19,611,577 to 28,736,888. The Polygon monthly row for June 2026 appeared on 2026-07-19 without a declaration; this note is that declaration.
