# Solana Transaction Lookup

> Solana Transaction Lookup is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Fetches on-chain details for a Solana transaction by signature, returning status, cost, and emitted events

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-transaction-lookup-b046dbeb -d '<json body>'
```

Example prompt: Can you look up the Solana transaction with signature 5jHgKqLmPwXvNzR3dYtQ8aBcUeF2oWsZx1iMnVrEpT6hCkJ7yDlG9bAuNfHmQw4s and tell me if it succeeded and what it cost?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

One Solana transaction, with its SOL and SPL balance changes — Genesis402 / UnyKorn Operator Network

## 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).
