Settled — preflight: pay / caution / avoid before you spend
One signed answer before your first payment to an unfamiliar x402 endpoint: fresh liveness probe on both verbs, parsed quote, payability verdict (payable / malformed 402 / cannot pay on either verb / unpriced), whether the payTo exists on-chain, the seller's other endpoints and settlement integrity (organic / concentrated / single payer / circular), the scout's real-payment delivery result, and a honeypot scan of the listing text. recommendation: pay | caution | avoid, with reasons. Every response is EIP-191 signed by Settled's published signer; verify at /v1/verify.

On-chain payments
Peak day 2026-09-28: 5 payments. Last indexed day 2026-09-28: 5. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-09-28; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 5 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
