# Utilia Solana Transaction Explainer

> Utilia Solana Transaction Explainer is a paid API for AI agents from api.utilia.ink, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-10).

Fetches and explains a confirmed Solana transaction by signature, returning balance deltas, program logs, compute unit usage, and retry-safe error classification.

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 utilia-solana-transaction-explainer-0b79632d
```

Example prompt: Can you explain what happened in Solana transaction 5KtPxL9Z...abc — I want to see the balance deltas, any program logs, how many compute units it used, and whether the error (if any) is safe to retry?

## When to prefer this

Use this endpoint when you need a human-readable or agent-readable breakdown of a specific confirmed Solana transaction — especially when you need balance delta accounting, log parsing, compute usage metrics, or need to determine whether a failed transaction is safe to retry without risk of double-execution. Prefer this over raw RPC calls when you want structured, classified output rather than raw JSON.

## Known failure modes

- Transaction signature not found or not yet confirmed — 404 or empty result
- Invalid Base58 signature format — 400 validation error
- Transaction too old and pruned from RPC history — data unavailable
- Network/RPC timeout when fetching transaction data — 503 or timeout error
- Insufficient payment via x402 — 402 Payment Required

## How this service works

Explain a confirmed Solana transaction, including balance deltas, logs, compute usage, and a retry-safe error classification.

## Output

Returns a structured explanation of a confirmed Solana transaction including: SOL and token balance deltas for all accounts involved, raw and parsed program logs, compute unit consumption, and a retry-safe classification of any errors encountered during execution.
