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.
Example use cases
Verify a crypto payment was received
“I just sent a Solana payment and want to confirm it went through — can you check transaction signature 3xvTq8YNmFaKrLpBQdJsHzR2uMcWE6gNfSa7DkXoCYtP4bVe1mTKL9wJp5qRsN8ZyAuGhFi and tell me if it's confirmed, how much the fee was, and who signed it?”
Debug a failed Solana transaction
“My Solana transaction seems to have failed. Can you look up signature 2HmRpLqJs9WbKxNyFcTaUv7rDgXe4QsYn6MiPokBVu3dCwZtLhJfE8oAR5c1mKqNsTG and tell me the status, any error, and which programs were involved so I can figure out what went wrong?”
Audit token balance changes from a DeFi swap
“I made a DeFi swap on Solana and want to see exactly which token balances changed. Can you pull up transaction 4JzQfYwPpLrBmUa8XcKsNe3TvGhD9RqZ7doFiW2VyCxbMtjSk6nHgAE1uLoP5eRs and show me the token balance changes, the programs that were called, and the timestamp?”
Technical details
Endpoint
POSThttps://api.vextorium.com/sol-tx-pago?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
