How this service works
Machine-readable decision procedure for verifying settlement on the Solana rail before an agent writes off a receivable or disputes a reversal. Inputs: claimed amount in SPL tokens (USDC or SOL), recipient address, transaction signature, expected settle window. Checks run in order: 1) signature validity via RPC getTransaction, confirm the tx exists and the block is not skipped; 2) confirmation status must be finalized, processed is not enough for write-off decisions; 3) recipient match, parse
Output
A JSON object containing a boolean 'ok' field, a plain-prose 'brief' (120+ words) describing the settlement decision procedure, a 'procedure' field with the same content, a 'generationSource' (deterministic/llm/reasoning), a timestamp, and the service/provider slug. The prose walks through signature validity, finalization status, and recipient match in order.
Example use cases
Write-off confirmation for agent receivables
“I received a claimed payment of 250 USDC on Solana to my wallet GHJ...XYZ with transaction signature 5Yx3...ABC — can you verify it's fully finalized so I can mark the invoice as paid?”
Dispute a Solana reversal claim
“A counterparty is claiming a SOL payment of 2.5 SOL to address RTY...789 with signature 9KL...QRS was reversed — can you run a settlement check to see if it actually finalized on-chain?”
Pre-release settlement gate for digital delivery
“Before I release the API keys to the buyer, verify that transaction signature 3MN...DEF for 50 USDC to address WER...456 has reached finalized status and the recipient address matches.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/solana-rail-settlement-verification-for-agents?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a structured, deterministic procedure to verify Solana SPL token (USDC or SOL) settlement before making a financial write-off decision or disputing a reversal. Prefer this over generic blockchain explorers when you need a machine-readable decision output with ordered checks (signature → finality → recipient match) specifically designed for autonomous agent workflows on the x402 payment rail.
Side effects
- Transaction signature not found on-chain — RPC getTransaction returns null
- Block containing the transaction was skipped — signature exists but block is invalid
- Confirmation status is 'processed' or 'confirmed' rather than 'finalized' — insufficient for write-off
- Recipient address in the transaction does not match the claimed recipient
- Payment not received — returns 402 if the x402 payment was not included
- Network or RPC timeout causing inability to retrieve transaction data
