# Utilia Solana Transaction Explainer

> Utilia Solana Transaction Explainer is a paid API for AI agents from api.utilia.ink, paid per call via x402, $0.008/call, status down (last checked 2026-10-13).

Fetches and explains a confirmed Solana transaction by its signature, returning balance deltas, program logs, compute unit usage, and a 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-7c210c5d -d '<json body>'
```

Example prompt: Can you explain what happened in Solana transaction 5KtP...xR2z — show me the balance changes, any program logs, how much compute 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 explanation of a confirmed Solana transaction — especially when you need to understand balance changes, debug program logs, assess compute usage, or determine whether a failed transaction is safely retryable. Prefer it over raw RPC calls when you want structured, enriched output rather than raw transaction data.

## Known failure modes

- Invalid or malformed Base58 signature returns a 400 error
- Transaction not yet confirmed or not found on-chain returns a 404 or empty result
- Network timeout or RPC unavailability returns a 503
- Signature for a transaction on a different cluster (devnet vs mainnet) may return not found

## How this service works

Give a Solana agent live compute-unit price bids for $0.002 per call via x402 USDC. One AgentCash command, no API key or subscription.

## Output

Returns a structured breakdown of a confirmed Solana transaction including: SOL and token balance deltas per account, program log output, compute units consumed, and a retry-safe error classification indicating whether a failed transaction can be safely resubmitted.
