Period: 11 Oct – 9 Nov 2026. Method: version 1.5, how the ranking works. Source: the public blockchains, read by us. Updated daily.

What didn't count, and why

$1,058,889 of the $1,604,979 didn't pass the filter:

• Fewer than 10 buyers: $888,206. Where it went
• Tied to the seller: $159,455.
• Removed after review: $5,936. Every removal, with its reason
• Marked by a memo only: $4,327.
• Seller paid itself: $963.73.

What counted

$546,090 across 552 ranked sellers, 25,413 buyers and 4,604,228 paid calls. $429,768 of it went to accounts we can't name yet: that money counts in the totals but isn't ranked.

Is it growing?

In the week to 11 Jan 2026, agents paid $489,725, and $63,374 counted. In the week to 8 Nov 2026, $402,421 and $280,038. Every week since the start.

What we see, and what we can't

We only see stablecoin payments on-chain, made over x402 and MPP: x402 on Base, x402 on Solana and MPP on Tempo. x402 is an open way for software to pay for a web request on the spot; MPP is Stripe's payment protocol. Card payments and other off-chain methods aren't included. We can't prove an AI sent each payment, so we say what we count and show what we left out. What's in and what's out.
