# Saylor Innovations Data Desk – Solana Transaction Lookup

> Saylor Innovations Data Desk – Solana Transaction Lookup is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Looks up a Solana transaction by signature and returns its status, fee, compute units, programs invoked, and SOL/SPL token balance changes per account.

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 saylor-innovations-data-desk-solana-transaction-lookup-dc78853b
```

Example prompt: Can you look up this Solana transaction for me — 5KtPn1LGuxhFiwjxErkxTb7XxtLVMFXnoRm6qXC4Z7RzmHbgtPmTHbP2WGFP3xXLUQFGWHnVpMnSQgdNHLJoCzT — and tell me whether it succeeded, how much the fee was, which programs it touched, and what SOL and token balances changed?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call lookup of a specific Solana transaction's on-chain details — including fee breakdown, compute units, program interactions, and per-account SOL/token balance changes — without running your own Solana RPC node or managing API keys. It is ideal for agents that occasionally need to verify, audit, or debug individual Solana transactions on demand.

## Known failure modes

- Invalid or malformed base58 signature returns an error field in the response
- Transaction not found on-chain (e.g. too old, wrong network) may return null or error
- Solana RPC downtime or rate limits may cause timeouts or empty responses
- Very recent transactions not yet confirmed may return a pending or unknown status

## How this service works

Solana transaction lookup: status, fee, compute units, programs used, and SOL and SPL token balance changes per account, read straight from Solana RPC.

## Output

A JSON object containing the transaction's chain identifier, signature, status (confirmed/failed), slot number, block time, fee in SOL, fee payer address, list of signers, programs invoked, compute units consumed, SOL balance changes per account, SPL token balance changes per account, instruction count, inner instruction count, log message count, and a source/note field indicating data provenance.
