x402 settlement census — 2026-09-06

We paid 316 conformant x402 hosts as an ordinary buyer and recorded what came back. Not a survey of what hosts advertise — a record of what they did when real USDC arrived.

REFUSED21367.4%
DELIVERED10031.6%
NO_CHALLENGE20.6%
MISMATCH10.3%

Two in three conformant hosts refused a correctly-signed payment. Being listed in a Bazaar index and answering a valid 402 is not the same as taking money and delivering.

Method

Buyer's-eye, exactly as a client experiences it:

  1. 1.GET the resource → 402 + a challenge (v2 header, or v1 body)
  2. 2.sign an EIP-3009 TransferWithAuthorization for accepts[0], with the EIP-712 domain taken from the challenge itself
  3. 3.GET again carrying PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1)
  4. 4.record status, bytes, content-type, latency, and the settlement tx the host reports

The payer never broadcasts a transaction and holds no ETH: the authorisation travels in a header and the host's facilitator submits it and pays gas. That is what EIP-3009 is for.

Caps, enforced in code: 0.05 USDC per host (50000 units), 5.5 USDC total. Actual spend 1.3398 USDC. Hosts asking more than the per-host cap were never contacted. Our own hosts are excluded by name — paying ourselves is a self-settlement, never a purchase.

Beneficiary concentration

174 distinct payTo addresses collect for 314 live doors — and the three largest collect for 91 of them.

payTohosts
0x2880EdfFF13100677Bf97A3CBdF3Bc34771C4E5E62
0xFFc458dB291b4ABcE020fE3de4f91F2770E537b118
0xEf879BFD6C4AccB8F795136de90246e1EC245e0611

A directory of many hosts is not a market of many beneficiaries, and a host count cannot show that.

Took a settlement and still refused (13 hosts)

These reported an on-chain settlement in their own PAYMENT-RESPONSE and then answered the retried request with 402/4xx anyway. Money moved; nothing was delivered. Check the chain yourself:

What this is NOT

  • Not a ranking or a recommendation. No host was contacted, before or after.
  • `REFUSED` is not proof of bad faith. A host may rate-limit, require an account, or have changed its terms between the challenge and the retry. From outside, all of those look identical.
  • One purchase per host, at one moment. A single refusal is not a pattern. A second round is what would make it one.
  • Not revenue. Every USDC left our own wallet. Paying anyone is a cost.
  • Not certification, not a conformity mark. Measurement of what happened, and when.

The move_a_self config

A second config records our own eight doors, paid by a wallet we control. It is here so the method can be checked against a case where the answer is known, and it is labelled so nobody mistakes it for demand: a self-settlement is never revenue. /api/revenue one_number stayed 0 throughout and self_settlements rose to 5. Five doors settled (all receipts status 0x1 on Base); three are priced at 250, 25 and 25 USD by design and were not bought — settling all eight would cost about 300 USDC.
