# Utilia Solana Transaction Evidence

> Explain a confirmed Solana transaction for $0.004 per call.
> Receive landed state, balance deltas, logs, compute use, a stable failure class, and a retry-aware next action.
> Fetch live priority-fee bids for Solana transaction agents at $0.002 per call.
> Responses are timestamped and can be localized to the writable accounts in a transaction.
> No account, subscription, or API key is required. Paid requests use x402 v2
> exact USDC payments on Solana mainnet, with explicit Base USDC aliases.
> Additional tools cover preflight simulation, token risk, PDF-to-Markdown, and audio normalization.
> PDF and audio bodies are processed in memory and are not persisted to disk.
> Access and settlement logs retain request and payment metadata, not media bodies.
