What it does

Solana Pay payment check by reference key: finds the transaction that carries a Solana Pay `reference` on mainnet and validates it like the Solana Pay spec's validateTransfer — succeeded, recipient received at least `amount` of the SPL token (or SOL), optional memo match. Returns signature, slot, block time, payer and amount actually received. Commitment is `confirmed` by default (`finality=finalized` available). Scan limit: the 10 newest signatures that reference the key are fetched and the 5 oldest of those are checked, oldest first (like @solana/pay findReference); the output lists exactly which were checked. `amount` may not have more decimals than the mint (looked up on-chain; 9 for SOL) — rejected with 400 before any payment is verified or settled. Live RPC data at request time. $0.005 per call.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/64151.json for the price and payment options.
3. Pay. Call GET https://x402.45-63-29-234.sslip.io/v1/solana-pay/verify. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
