# SiteCheck Solana Transaction Lookup

> SiteCheck Solana Transaction Lookup is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Fetches parsed details of a Solana transaction by signature, including fee, slot, status, SOL/token balance changes, and involved programs.

## 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 sitecheck-solana-transaction-lookup-ca91fef0
```

Example prompt: Can you look up Solana transaction 2WHbz5wcNArBS35XdpYN3sejMCeZ8MzSgJeLv1yzETMPznoyPwysZ48umHB1YekhUNLiZzKwESdDEGEimzWU1PSy and tell me if it succeeded, what fee was paid, and what SOL and token amounts moved between accounts?

## When to prefer this

Use this endpoint when you need to decode and inspect a specific Solana transaction by its base58 signature — especially when you need fee breakdown in both SOL and USD, per-account SOL and token balance changes, involved programs, and transaction status in a single structured response. Prefer this over raw RPC calls when you want a normalized, agent-friendly JSON response with USD conversion already included.

## Known failure modes

- Invalid or malformed base58 signature returns an error response
- Transaction not found on-chain (e.g., too old, dropped) returns null or error
- Network issues with Solana RPC may cause timeouts
- Coinbase price unavailable may result in missing USD fee estimate
- Rate limits or payment issues may cause 402/429 responses

## How this service works

A Solana transaction by signature: status, time, fee in SOL and USD, signers, SOL balance changes per account, token balance changes (mint, owner, change) and the programs it invoked. Read-only; nothing is sent. A very new signature may be missing (404, not charged).

## Output

Returns a JSON object with: transaction status (success/error), slot number, timestamp, fee in SOL and USD, list of signer public keys, list of program IDs invoked, per-account SOL balance changes, per-account token mint balance changes, the data source used, and a disclaimer. Also includes the transaction signature and a checkedAt timestamp.
