How this service works
A Sheaf of Attestations. Two to twenty signed JSON observations, one per Base transaction hash supplied, each carrying the same fields and independent signature as the single settlement attestation — plus a certificate binding a sha256 digest of the sheaf's evidence hashes, so one verify URL answers for all of them. Instant. Full listing: https://scvd.store/menu/attestation_bundle. MCP tool: buy_attestation_bundle.
Output
A JSON object containing: a full text 'sheaf of attestations' for each supplied transaction hash, an ed25519 signature over the bundle, a permanent verify URL, a signed patron certificate with cert_id and date, a patron badge SVG URL, the patron number, the amount paid in USDC, and an optional tip field.
Example use cases
Auditing a batch of agent micropayments
“I need a signed attestation bundle for these five Base transaction hashes from our agent's x402 spending last week — can you pull that from SCVD General Store and label it under 'AuditBot 3'? Hashes: 0x1111...a, 0x2222...b, 0x3333...c, 0x4444...d, 0x5555...e.”
Proving settlement to a downstream counterparty
“We need to prove to our partner that ten x402 payments actually settled on Base — can you get a signed attestation bundle from SCVD for these ten transaction hashes and share the verify URL with them?”
Compliance record for agent payment log
“For our monthly compliance file, please pull a signed attestation bundle from SCVD General Store covering these three Base tx hashes and name the certificate 'ComplianceAgent July 2026'.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/attestation_bundleWhen to prefer
Choose this endpoint when you need a cryptographically signed, human-readable attestation bundle for 2–20 Base blockchain transaction hashes in one call — especially in x402 payment workflows where you need a trust artifact, patron certificate, and permanent verify URL in a single response. Prefer it over single-hash settlement checks when batching is needed, and over generic blockchain explorers when you require an ed25519-signed, off-chain attestation suitable for sharing with counterparties or storing for compliance.
Side effects
- Fewer than 2 or more than 20 transaction hashes supplied — schema validation error
- Duplicate transaction hashes in the list — rejected by pattern validation
- Malformed hash (not matching 0x[64 hex chars]) — schema validation error
- Transaction hash not yet confirmed on Base — attestation may reflect unconfirmed state
- Payment not received or x402 payment flow failed — endpoint returns 402 or payment error
- Network timeout contacting scvd.store — no bundle returned
