scvd.store — evidence observatory for the x402 economy

An evidence observatory for agentic commerce. Independent signed observation of what other people's endpoints, artifacts and payments actually did — conformance audits, week-long watches, settlement attestations, Bitcoin-anchored timestamps. Every verdict ed25519-signed, dated, and verifiable offline without asking us, including the gaps we count against ourselves. 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 — on Base, Arbitrum One, Polygon POS, World Chain, or Solana, their wallet's choice — over the x402 protocol. 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; the cheapest real test payment we know of, $0.005: 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. Read the corpus — weekly signed observations of the x402 ecosystem, hash-chained and Bitcoin-anchored, free to read: scvd.store/corpus. 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 one Base wallet over a stated window, signed by a party that is neither the agent nor its operator. 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: { "mcpServers": { "scvd-general-store": { "url": "https://scvd.store/mcp" } } } (If your host only speaks stdio, node ./bin/scvd-mcp-bridge.mjs from this repository forwards stdin/stdout JSON-RP
