How this service works
Signed Solana settlement verification (did tx credit amount of mint to payee). Free preview: GET /settle/preview
Output
Returns a signed settlement verification object containing a verdict enum (VERIFIED, REFUTED, UNCONFIRMED, NOT_FOUND, or not_evaluated), the chain identifier, the signer address, the original transaction signature, and optionally the slot number and commitment level at which the transaction was observed.
Example use cases
Release digital goods after payment
“Before I send the download link, can you confirm that Solana transaction 4xK9pLmQr... actually sent 5000000 atomic USDC units to my wallet address 9Abc1... and return the verdict?”
Validate x402 payment in agent workflow
“My x402 payment flow just completed — can you verify that transaction signature 3TqWmNpR... credited 250000 atomic units of the USDC mint EPjFWdd5... to payee BzXc2... so I know the settlement is VERIFIED before continuing?”
Audit historical Solana payment
“I need to audit whether transaction A8kLpY7... on Solana actually transferred the correct 1000000 USDC atomic units to address DqZ3m... — can you check and tell me the verdict and the slot it was confirmed in?”
Technical details
Endpoint
GEThttps://x402.nsgoods.org/settleWhen to prefer
Use this endpoint when you need a signed, structured attestation that a specific Solana SPL token transfer (typically USDC) credited a precise atomic amount to a known payee address — especially in automated x402 payment workflows where a machine-readable VERIFIED/REFUTED verdict is required before releasing goods, services, or access. Prefer this over raw Solana RPC calls when you need a normalized, schema-versioned response with explicit verdict semantics rather than raw transaction data.
Side effects
- Transaction not found on-chain returns NOT_FOUND verdict
- Transaction found but amount or payee does not match returns REFUTED verdict
- Transaction not yet confirmed returns UNCONFIRMED verdict
- Invalid or malformed base58 transaction signature causes request error
- Incorrect payee or amount format leads to REFUTED rather than an error
- Network or RPC unavailability may cause timeout or error response
