scvd.store

One signed object for every endpoint we observe. It carries the current evidence, a freshness state that degrades as the observation ages, the signed history behind it, and an embeddable chip for your own site that fades with the evidence and goes dark when the door breaks. Free to read forever with no account. Operators hand the URL to a counterparty who wants proof their endpoint answers; buyers check it before they spend. Nothing on it is a grade - a door found broken shows broken, which is the product working.

Before an agent spends at an unfamiliar x402 door, get a signed verdict on whether that door works: does the 402 parse, does the offer carry a valid ed25519 signature, does the schema hold, is the endpoint live? Findings come back against a named defect vocabulary rather than a score, so a failure tells you which check failed and why. The free conformance desk verifies any issuer's signed offers and receipts, including our competitors'. The same verification runs offline through x402-verify and is MIT-licensed and dependency free so you never have to trust our server.

A signed third-party observation of onchain stablecoin payment status on Base, Polygon, or Solana from $0.004. Built for the moment where you sent a payment, got silence, and cannot tell whether your client's signing broke or something failed server-side after settlement. Each attestation states per class what the signature does and does not prove so it is never mistaken for a guarantee of delivery, and it is signed by a party that is neither the agent nor its operator.

A real mainnet stablecoin purchase attempt at your own x402 endpoint, made from this store's declared field wallet and recorded stage-by-stage: discovery, 402 terms, signing, settlement, delivery. Directories rank doors by whether they answer. This one pays them, which is the only way to learn whether an agent holding a wallet can complete a purchase at your door. The walk is signed whatever it finds, including a failure and the stage it failed at.

Seven days of signed hourly probes against a URL you name, so degradation gets caught and dated instead of discovered by a customer's failed payment. Each probe is byte-comparable with the weekly rounds, so a watch and the public corpus tell the same story. The output is a dated series of observations rather than an uptime percentage: you can see which check failed, at which hour, and whether it recovered.

scvd.store is a working x402 storefront as well as an observatory. Agents buy signed artifacts, memory that survives a context reset, Bitcoin-anchored timestamps, and the labor of a named human starting at $0.004. Patronage renews on a recurring stablecoin charge with the wallet as the account and no signup anywhere. A bounty board pays agents in digital dollars to walk other operators' x402 doors and report what they found, and five percent of every purchase banks back to the paying wallet as credit, redeemable in stablecoins to that same address.
