How this service works
Coinlight charges USDC per API call with the x402 protocol on Solana and Base.
Output
A JSON response containing: a one-sentence plain-English explanation of the transaction (e.g. 'Wallet X swapped 0.5 SOL for 1,203,442 BONK on Jupiter'), the action type (swap, transfer, mint, failed, etc.), net asset changes for the signer, and the transaction fee. Chain is auto-detected from the input hash format.
Example use cases
Debugging a failed DeFi swap
“I think my Jupiter swap failed — can you look up this Solana transaction 5KtPn1wHKuFVEQ7VStP7YAEoydCVNfA79xjxC3mBhHEP9VhTMVqfCaJCkJQUHVGJJZkApZNAsDC2v9T4wJdV3xA and tell me in plain English what actually happened, the action type, and whether any tokens moved?”
Auditing a Base ETH transfer
“Someone sent me a Base transaction hash 0x6a602056e3c454b112290adf0e4a538960ee6b63117a74c31a3a9c62c526b840 — can you explain what it did, what kind of action it was, and what the net asset changes were for the signer?”
Explaining a wallet activity to a client
“I need to explain this Solana transaction to my client in simple terms — can you decode signature 3xFf4YZ8kP2mQwLnVbT6sRhDcUjNpAeKiWoGvXqBdSYmr and tell me what happened, the action type, and what assets changed hands?”
Technical details
Endpoint
GEThttps://coinlight-app.vercel.app/p/tx-explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a human-readable explanation of a single Solana or Base transaction — especially when the user provides a raw hash or signature and wants to know what happened without reading raw blockchain data. It auto-detects the chain, so no need to specify Solana vs Base. Prefer this over generic block explorers when you need structured output (action type, net changes, fee) rather than just a link.
Side effects
- Invalid or malformed transaction hash/signature returns an error
- Transaction not found on chain (wrong chain or very recent/unconfirmed tx)
- Chain detection failure if hash format is ambiguous
- Network or RPC timeout for slow chain responses
- Rate limiting or payment failure if x402 payment not processed
