How this service works
The Company an Address Keeps. REQUIRES ?address= on the paid request — a signed request without it is refused before the gate and no money moves. A signed JSON record — the subject address verbatim and its v1 digest, never_seen, one entry per signed week the address was advertised (week, sequence, snapshot digest, the doors with verdict and offered terms), dated drift between weeks, the subject's standing note verbatim when one exists, the shared-wallet caveat inline, the ho…
Output
Returns a JSON object containing: a signed ed25519 certificate (cert_id, date, item, patron_number), the full provenance deliverable as text describing the address's on-chain associations, a badge_url SVG, a verify_url for public certificate verification, the amount paid in USDC, and an optional tip amount.
Example use cases
Vendor wallet due diligence before payment
“Before I send payment to 0xAbCd1234...5678, can you pull a signed provenance report on that address so I know what other wallets and protocols it's been associated with on-chain?”
Counterparty screening for DeFi trade
“I'm about to enter a large DeFi position with a counterparty at Solana address 7xKf9...mNpQ — can you get me a signed certificate of their on-chain associations so I can assess the risk?”
Agent fleet wallet reputation check
“My AI agent fleet received a payment from 0xDEAD...BEEF — can you fetch a provenance report on that address and name the certificate 'incoming payment audit' so I have a signed record of who it keeps company with?”

Endpoint
GEThttps://scvd.store/api/buy/provenance_check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, independently verifiable provenance report on a specific blockchain address — particularly when you need a certificate you can show to a third party or anchor to a Bitcoin-timestamped corpus. Prefer this over generic blockchain explorers when you need a signed attestation artifact rather than raw transaction data, and when you're operating in an x402 agentic commerce context where signed receipts matter.
Side effects
- Invalid address format — address must be a valid EVM hex (0x + 40 hex chars) or Solana base58 pubkey (32-44 chars)
- Payment failure — x402 payment not completed or insufficient USDC balance
- Address not found in corpus — observable on-chain data may be sparse for very new or inactive addresses
- Network unavailable — Base, Polygon, Arbitrum, World, or Solana RPC issues may delay resolution
- Rate limiting or quota exhaustion at $5 USDC per call
