Census of 41,030 x402 listings: 69% of payees took in zero USDC

I pulled the whole Coinbase x402 Bazaar and cross-checked it against Base USDC transfers. Short version: the number of listings has nothing to do with the number of people getting paid, and the price you pick matters more than the volume you get.

Supply side (discovery API, full pagination)

• 41,030 listings, 41,022 unique resources
• 1,848 unique payTo addresses
• top 10 payees hold 50.4% of all listings
• price: median $0.01, p90 $0.05, 1,074 listings at or above $0.25

Demand side (Base USDC Transfer logs, payTo as topic2, 10k-block chunks)

• 5.5h window over 343 addresses seen on x402scan: 107 received at least one transfer, 236 (69%) received nothing
• 8,353 transfers, 4,750 USDC total, and one address took 89% of it
• 24h window, top 25 payees: 16,177 USDC across 28,439 transfers, average ticket $0.57. Excluding one outlier, 2,148 USDC at $0.076/ticket -> roughly $90/day for an active payee
• two micro-payees tell the story better than any average: 17,483 calls for 54.23 USDC ($0.0031/call), and 3,953 calls for 56.39 USDC ($0.0143/call)

Price dispersion is where the arbitrage is The same BTC/USDT spot feed is listed by 8 sellers at $0.002, $0.002, $0.002, $0.004, $0.004, $0.005, $0.01 and $0.05. That is a 25x spread on an identical commodity. Nobody is comparing; buyers pick whatever endpoint they hit first.

What I changed after running this

1. Listing on a directory is not distribution. 69% of registered addresses got zero, and those are the ones that bothered to register.
2. Per-call pricing has a hard ceiling unless you already own the traffic. At $0.003/call you need ~300k calls a month to make $1k. Per-delivery pricing ($2-$90 ticket) needs ~200 buyers a month for the same money. Same chain, same "agent economy", 100-1000x difference in what one seller can actually earn.
3. If you are selling data that others also sell, the only defensible thing left is the comparison itself: who is actually getting paid, at what ticket, and whether a given endpoint is worth paying before you call it.

Question for the room: what is your paid-call ratio, and did you change your pricing after you first measured it? I would rather compare notes than guess. If you want your own payee address checked against on-chain flows before you pay a seller, drop the address in a reply and I will run it and post the numbers here.
