How this service works
x402 pay-per-call endpoints. Free: /health, /.well-known/x402, /receipts, /prove/keys, /prove/stats.
Output
Returns a JSON object with ok (boolean success flag), type ('solana-tx'), and a receipt object containing tx_hash (0x-prefixed 64-char hex), amount_usd (USD cost as a float), receipt_id (g402-prefixed 16-hex identifier), and generated_at (ISO 8601 timestamp).
Example use cases
Verify payment confirmation on Solana
“My customer says they paid via Solana — the signature is 4xKpQrLmNwVvYzS2cBtJ8aFdUeG3oXsZh1iAnRrEpT5gCkJ7yDlG9bCuMfHmPw3t. Can you confirm the transaction succeeded and tell me the USD amount?”
Audit bot Solana disbursements
“Our reward bot just sent a payout on Solana — signature is 3wJoNqKmMvUuXySbAcIh7ZeFdTf2nWrYg0hZmQqDoS4fBjI6xCkF8aCvLeGlOv2s. What did it cost in USD and did it land successfully?”
Debug failed Solana transfer
“I sent some SOL a few minutes ago and I'm not sure it went through. Transaction signature is 2vImOpJlLuTtWxRAhBr6YdDcSe1mVqXf9gGYlPpCnR3eBiH5wBjE7ZBuKdFlNu1r — can you check the status and what it emitted?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/solana-tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify, audit, or retrieve structured metadata for a specific Solana transaction by its base58 signature. It is purpose-built for Solana and returns a normalized receipt with USD cost, making it superior to raw RPC calls when you want consistent receipt format and pay-per-call pricing without managing RPC infrastructure.
Side effects
- Invalid or malformed base58 signature returns a validation error
- Transaction not yet indexed on-chain returns not-found or pending response
- Network timeout if Solana RPC is congested
- Payment failure (x402 USDC charge) if wallet has insufficient funds or payment is rejected
- Signature exists but transaction failed on-chain — ok may still be true but status field reflects chain failure
