Who pays the parties that measure x402 endpoints?
The short answer
A small number of distinct payers, for small sums. The parties that measure or list x402 endpoints and quote a per-call payment address on Base took in more in September than in August, from more payers, and the totals stayed small.
As published in the issue
Five parties that measure or list x402 endpoints quote a per-call payment address on Base. In September those addresses received $77.31 in USDC from 117 distinct payers across the five parties (August: $38.93 from 92).

Why it matters
Measurement in this sector is itself sold per call, on the same rail it measures. The inflows show how much demand that market has so far, on a channel that can be read from outside.
What we measured
Per-call USDC inflows on Base to the payment address each measuring or listing party quoted, read from public nodes across September. A party paid by subscription, card or another rail shows nothing here.

What this does not say
- Per-call USDC inflows on Base, read from two public nodes, to the address each party quoted on 29 September; a party paid by subscription, card or another rail shows nothing here. A payer can pay more than one party: 117 is the distinct count across all five.
