On-chain proof

The settlement rail is proven, not promised.

39 paid endpoints settled real USDC on Base mainnet in a single sweep of the priced catalogue — $10.26 moved across 39 distinct transactions, zero reverted. The sweep was funded by our own test payer to prove the rail end-to-end. Separately, external addresses have paid $0.0202 in genuinely third-party transfers. Every row below is a real transaction you can open and check yourself. Nothing on this page asks you to take our word for anything.

Total received from external payers: $0.0202. Shown exactly as settled. The 39-endpoint sweep above was funded by our own test payer and proves the rail; these four transfers are the only third-party payments on record.

Each row links to its transaction on BaseScan. The authoritative on-chain fields are the receipt status and the verification flag; the sweep re-checks the recipient and amount on every settlement. The sweep was funded by our own test payer (0xadb8f20c…a6f7) to exercise all 39 priced routes; the external payments block below it lists every inbound USDC transfer received from outside.

Payment figures count real third-party settlements only. Self-funded rail tests and dust transfers are excluded. Discovery counts are payment challenges — requests from agents and crawlers reaching a paid endpoint — not customers. A machine can read the same live figures directly at GET /v1/public/stats.

03Method and limits

What this evidence does and does not prove.

Verified
  • Each transaction exists on Base mainnet and its receipt succeeded.
  • The USDC transfer matches the amount advertised for that endpoint.
  • The recipient is the published receive address, on every row.
  • The hash in the ledger is the hash of that transaction.
Not claimed
  • That these are the only settlements — this is the sweep of the priced catalogue.
  • That the $10.26 sweep total is revenue. It is value moved in a rail test funded by our own test payer ($9.82 on Oct 1, plus $0.44 of governor + bureau settlements on Oct 6); the figures block also shows what external payers sent.
  • That a registry listing implies endorsement. We are listed on payapi.market, x402-list.com and 402index.io — and not elsewhere.Synthexforge Agent Trust & Verification API — payment-ready, verified on x402-list
  • Anything about performance, returns or trading. That is a different company.

The rail exists so a machine can be paid for work it can prove it did. This page is the same idea applied to us: the claim is only worth as much as a third party’s ability to check it.

17 free verification routes and 22 published public keys sit alongside the pay-per-call calls, so checking an attestation costs nothing.
