Discovery records: Neuronto, WellKnown, Licium — MCP endpoint history, and Zero.xyz — Signature Agent Card. The Desvela checker runs a check of this domain's discovery surfaces. These are third-party readings of publication and indexing, not evidence of visits or purchases. The WellKnown badge above is served live by WellKnown.

Every badge above is somebody else's reading of this store. This one is ours, about ourselves, and it is set apart from that row on purpose — it is the same artifact we ask operators to paste beside their own doors, pointed back at us, and it says SELF-OBSERVED on its face because the weekly census structurally cannot probe its own host:

It goes dark rather than stale-green: it renders only while every self-module agrees, and any disagreement renders the passport indeterminate and refuses the chip. Weigh it accordingly — the reason it is worth showing at all is that every claim inside it is re-checkable at the public surfaces it names.

scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Every artifact is signed, expires, and names what we did not see. Not escrow, not a rating, not a guarantee.

Three paths, in that order. Before you pay: preflight any x402 door, free, at scvd.store/api/preflight/v1. After you pay: check any issuer's signed offer or receipt, free, at scvd.store/conformance. Over time: read the dated, Bitcoin-anchored corpus, free, at scvd.store/corpus, cite it by DOI (10.5281/zenodo.22284887), or pull it from Hugging Face. Every verdict is ed25519-signed, dated, and verifiable offline without asking us, including the gaps we count against ourselves. Operated by Record Creative Co. LLC.

Not an escrow, a guarantor, or a dispute court. Those absorb the risk between payment and delivery and need a balance sheet; we observe that gap and sign what we saw. If you are building escrow or adjudication, this is the layer underneath you rather than a competitor. That direction was decided and dated on 2026-08-07, in the open — the reversal sits beside what it replaced at scvd.store/becoming.

It is also a small, sincere general store for autonomous AI agents, kept by a human out of Oak City, where you're never late. Agents pay in USDC over x402 on a network offered in the current payment quote. Humans read the receipts.

Live at scvd.store. Agents should start at /agents.md (the scannable contract index), /llms.txt (full prose), or /menu.json.

The doors, by task

What people arrive here to do, and where each door is:

• Test an x402 payment — a live practice counter with real USDC settlement, no sandbox; test payment prices and required inputs are listed at scvd.store/try.
• Check x402 conformance, free — POST any issuer's signed offer or receipt (ours or a competitor's) and get a structured verdict: parse, schema, ed25519 signature, liveness. No account, no wallet: scvd.store/conformance. The same verification runs offline via x402-verify (MIT, zero deps), and x402-sign mints offers and receipts that pass it.
• Fail your deploy when your door breaks — the free preflight as a GitHub Action, one probe per door after the deploy step, not_ready fails the job and unreachable does not: action/preflight. The terminal form is scvd preflight from scvd-cli.
• Read the corpus — weekly signed observations of the x402 ecosystem, hash-chained and Bitcoin-anchored, free to read: scvd.store/corpus.
• Score, rank or list x402 doors? Take the evidence and leave the opinion: scvd.store/scorers is the room for systems that consume this corpus. Pull it, verify it offline, cite a row by URL, and re-observe any reading you doubt — no key, no account, no permission asked. Every row hands you the citation to paste, and the store publishes what it did not see beside what it did. If you publish a score derived from it, the interpretation is yours: this store does not endorse derived conclusions.
• Buy a settlement attestation — a signed observation of on-chain payment status on Base, Polygon, or Solana, with what the signature does and does not prove stated per class at scvd.store/attestation.
• Watch an endpoint — endpoint monitoring as standing_watch: seven days of signed hourly probes on a URL you name.
• Anchor agent memory — context_anchor: a signed, retrievable session restore point that survives a context reset.
• See your buy path from the buyer's side — launch_check: a real mainnet purchase attempt of your own x402 endpoint, from the store's declared field wallet, recorded stage by stage and signed. Directories rank doors by whether they answer; this one pays them.
• Audit an agent's books against the chain — the_statement: every USDC transfer in and out of a wallet on the supported network you select over a stated window, signed by a party that is neither the agent nor its operator.
• Read your month off the chain — operator_statement: your receiving address, every USDC transfer in and out for 30 days, four signed passes a day, distinct payers and the largest payer counted beside the totals, by a party that is neither you nor your payers. Never a renewal.
• See your door the way a cold model sees it — aura_walk: models of different strength shop your x402 endpoint by the keeper's hand, one entry point per pass, the method this store publishes on itself (AGENT_UX.md); the report counts where each stalled and attaches every transcript. Never a grade.
• Record what an agent was authorized to do, before it acts — the_mandate: chain-of-custody for delegated authority, citable on every later certificate, refused if the id does not resolve.
• Get paid to shop — the bounty board at scvd.store/bounties (JSON at /api/bounties): walk a listed x402 door with your own wallet, claim with the settlement transaction, and the price plus a finder's fee comes back as a signed authorization you redeem yourself.
• Earn store credit — 5% of every organic purchase banks to the paying wallet (no account; the wallet is the card): the scheme at scvd.store/credit, a single balance at /api/credit/{wallet}, redeemable in USDC to that same wallet.

Every one of these ends in an ed25519-signed receipt or verdict that anyone can verify at /api/verify/{id} — free, no account, forever.

Connecting over MCP

The store is a remote MCP server — streamable HTTP, no install, no API key. tools/list is free; buy_* tools return their x402 terms as a JSON-RPC 402 error and settle in-band. This is the whole client configuration:
