PayAI is an x402 facilitator with USDC settlements observed on-chain. This page compares the measured volume across chains and time windows, links the settler addresses used for attribution, and shows listed services settling through those addresses. The figures cover tracked addresses only; volume does not measure service quality or prove delivery.

By chain

Base$6.6k 3,057 buyer-days$1.80M allsince
Solana$1.2k!366 buyer-days$14.1k! allsince

! Solana Vol 30d and Vol all span the ingest gap (08-24 to 09-22): they read low.

How buyer-days are counted

Buyer-days are the distinct buyers of each day, summed over 30 days, per chain from the daily snapshots: Base 3,057, Solana 366. A buyer active on five days counts five times, and buyers on different chains or tokens are not de-duplicated, so this is not a head count of buyers.

Vol today is today so far in UTC. Vol 7d and Vol 30d include today. Vol all covers the measured history since Jan 2026. Since is the start of our measurement window. Listed chains have no measured volume yet. A ! marks incomplete ingest in that window.

3,423 buyer-days over 30d: buyers are an upper bound, not an exact head count. Distinct buyers are counted per chain from the daily snapshots. A buyer active on more than one day is counted once per active day, and buyers on different chains or tokens are not de-duplicated, so total_upper_bound_30d is an upper bound, not an exact head count. Prefer the per-chain figures.

Services listed in this directory that have settled on-chain via this facilitator. Volume is the service 30d figure over its payout mapping (a conservative floor, USDC via measured facilitators only); services that share a payout address are counted at the address level here. The all-time count is null until the hourly precompute records it.

Listed-service figures: Read as of . Source JSON. Measurement methodology.

Definitions and limits

A facilitator verifies and submits x402 payments. Its settler addresses originate settlement transactions or pay the network fee. Volume is attributed to the addresses listed here, not to a verified legal identity of the provider.

USDC amounts use 1 USDC = 1 USD. Coverage is a measured floor over tracked addresses and chains, not total ecosystem activity. Volume does not establish service quality or successful delivery. Buyer-day totals are upper bounds on distinct buyers.

Read times describe when each displayed source was read; last activity identifies a UTC day bucket. The source does not publish a content-modified timestamp for these aggregates. Last seen in the settler table is a discovery date, not settlement time.
