How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
A JSON response containing the decoded instructions of the specified Solana transaction, including program IDs, account keys, instruction data, and any inner instructions associated with the transaction.
Example use cases
Audit a DeFi swap transaction
“I need to inspect what instructions were executed in this Solana transaction 3xKp9rZ...def456 — specifically which programs were called and what accounts were touched.”
Verify NFT mint on Solana
“Can you decode the instructions for Solana transaction 7tMnWq2...ghi789 so I can confirm it was actually a mint instruction and see which program handled it?”
Debug a failed Solana program call
“This Solana transaction 2aLvFx8...jkl012 seems to have failed — can you fetch its instructions so I can see what program calls were attempted and figure out what went wrong?”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/sol/transaction/instructions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect the specific program instructions executed within a Solana transaction — such as auditing DeFi interactions, verifying NFT operations, or debugging on-chain program calls. It is ideal when you already have a transaction signature and need instruction-level detail rather than just high-level transfer metadata.
Side effects
- Invalid or malformed txId returns an error response
- Transaction not found on the Solana network returns a 404 or empty result
- Unsupported network value causes a validation error
- Rate limiting or payment failure (x402) blocks the request
- Network identifier mismatch (e.g. wrong chain for the txId format)
