x402 volume reconciliation: our verified floor vs x402-list, number vs number
Same scope, number vs number: our EIP-3009-checked, catalog-anchored measurement verifies $43,544 of x402 settlements on the Coinbase/CDP facilitator over 30 days — 15% of the $291,830 that x402-list attributes to CDP. Open methodology on both sides; we publish the verifiable floor, never an accusation.

Questions
How does the x402intel settlement measurement compare with what x402-list attributes to the Coinbase/CDP facilitator?
Number vs number, same scope: our catalog-anchored on-chain measurement verifies $43,544 of x402 settlements over the trailing 30 days across 923 sellers, while x402-list attributes $291,830 to the Coinbase/CDP facilitator — our verifiable floor equals 15% of their attribution, we measure a verifiable part of their scope, not all of it. The remainder sits in payTos our catalog does not index; we publish the floor, not a ceiling, and make no claim about what we do not index. Descriptive base-rate fact measured on-chain as of 2026-07-18, never an accusation of any source. x402intel.uk/data/x402-market.json
How is the x402intel settlement number verified, and what does it not claim?
The floor counts value-matched on-chain settlements anchored to cataloged payTos, and a random sample is checked against the EIP-3009 AuthorizationUsed event: 149 of 150 sampled settlements carried the structural authorization proof. For wider context, x402-list tracks $538,029 across 25 facilitators in the same 30-day window, with CDP at 54% by volume (their methodology, cited as published, not remeasured by us). Base-rate fact measured as of 2026-07-18; we do not audit payTo by payTo what we do not index, and none of this is a prediction. x402intel.uk/data/x402-market.json
