# Solana Transaction Status by Signature

> Solana Transaction Status by Signature is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Returns the confirmation status, slot, timestamp, fee, signers, programs invoked, and token balance changes for a Solana transaction given its base58 signature.

## 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 solana-transaction-status-by-signature-6de0dccc -d '<json body>'
```

Example prompt: Can you check the status of this Solana transaction for me — signature 5KtPn1LGuxDs4W9ioR4MuyAUCp5HAetFSLKTHXTJZCr3GXz3FKdxA1GHLpBGCHsJ8vBrPfqJ9f6M? I want to know if it confirmed, what fee was paid, and which tokens changed hands.

## When to prefer this

Use this endpoint when you need a single, structured lookup of a Solana transaction by its signature and want confirmed status, fee, signer, program, and token change data in one call — particularly when you need token balance deltas and program invocation details that raw RPC responses leave unformatted. Prefer this over raw Solana RPC calls when you want a clean, normalized response without parsing complex Solana transaction structures.

## Known failure modes

- Invalid or malformed base58 signature returns an error field
- Transaction not found on-chain if signature is too new or pruned from RPC history
- Timeout or RPC unavailability if Solana network is congested
- Token metadata (symbol) may be null if mint is unrecognized
- Processing status returned for very recent transactions not yet finalized

## How this service works

Solana transaction status by signature: confirmed / failed / processing, slot, time, fee in SOL, signers, programs invoked and token balance changes.

## Output

Returns a JSON object with: transaction signature (firma), confirmation status (estado: confirmed/failed/processing), network (red), slot number, UTC timestamp (fecha_utc), fee in SOL (comision_sol), list of signer addresses (firmantes), list of programs invoked (programas), a Solana explorer URL (explorador), token balance changes array (cambios_de_tokens) each with mint address, symbol, owner, and change amount, and any error details if the transaction failed.
