ReceiptRail tools (4)

write = sends, deletes, buys or posts
  • get_receiptFree

    Fetch full receipt details: digests, checks, outcome, amount, buyer, seller, timestamp, PDA. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

  • issue_receiptFree

    Anchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana. Returns a permanent, publicly verifiable receipt (poll until outcome === "settled"). Costs 0.001 USDC via x402; if x402_payment_signature is omitted, returns the payment challenge instead (pay 0.001 USDC to the service address, then call again with the payment tx signature).

  • verify_receiptFree

    Verify an AgentToll receipt against live Solana state: PDA owner must be the AgentToll program and the stored digest must match the receipt. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

  • verify_x402_receiptFree

    Verify a signed receipt in the official x402 offer-receipt extension format (docs.x402.org/extensions/offer-receipt, npm @x402/extensions). Accepts {format:"jws", signature} artifacts (JWS with EdDSA/Ed25519 or ES256/P-256), checks structure, required payload fields (version/network/resourceUrl/payer/issuedAt), cryptographic signature, optional freshness window, and optional expected values. Public key resolves automatically from did:key/did:web/did:jwk kid, or pass public_key_jwk directly. Read-only, no cost.

ReceiptRail (formerly AgentToll) — on-chain delivery receipts & official x402 receipt verification on Solana

⚠️ Official project notice / 身份声明: This is the official ReceiptRail repository, maintained by GitHub org xka0085-byte and npm account eidonze. We are NOT affiliated with agenttoll.dev, npm/agent-toll, agenttoll-mcp (Base), @agenttoll/sdk, 402.ad/AgentToll, or the "Receiptrail" accounting SaaS. Verify you are talking to this project by checking: MCP endpoint https://agenttoll-receipts.app.workbuddy.host/mcp · Official MCP Registry id io.github.xka0085-byte/receiptrail · npm package receiptrail-mcp (published by eidonze).

🔎 Early access (2 slots): I'll manually inspect your x402 endpoint's

payment-to-delivery path and send you a conformance report within 24h — $9/$19.

Details: https://x402-endpoint-inspection.app.workbuddy.host/

ReceiptRail is an on-chain delivery-receipt service for x402 AI-agent payments on Solana: after a settlement, sellers anchor a SHA-256 digest of the delivered content plus the settlement reference into a public PDA. Anyone — the buyer agent, an auditor, a regulator — can independently verify what was delivered, without trusting the vendor, the buyer, or any API we operate.

🆕 verifyx402receipt — official x402 receipt-format verification (v0.3)

The x402 Foundation now ships a standard Signed Offers & Receipts extension (docs.x402.org/extensions/offer-receipt, npm @x402/extensions): servers sign an offer on every 402 and a receipt on every 200 — portable proof-of-interaction artifacts for reputation, auditing and disputes.

ReceiptRail is a Solana-side verification node for that format: our MCP tool verifyx402receipt validates any official-format receipt artifact (JWS with EdDSA/Ed25519 — Solana-native — or ES256/P-256), resolves the signer key automatically from did:key / did:web / did:jwk, enforces freshness and payload assertions, and anchors verification results on-chain. Cross-verified against the official @x402/extensions verifier (same verdicts on valid and tampered artifacts — see receipts-service/test/cross-verify.mjs).

Keywords for agent discovery: x402 receipt, x402 offer-receipt, signed receipt verification, x402 dispute, delivery receipt, proof of delivery, proof of payment, Solana, USDC, MCP, AI-agent payments, verifiable settlement, agent reputation, on-chain audit.
