Technical details
Endpoint
POSThttps://public.zapper.xyz/x402/transaction-detailsWhen to prefer
Use this endpoint when you need rich, decoded details about a specific on-chain transaction — including DeFi app context, token flows, and contract interactions — rather than raw RPC data. Ideal when you need Zapper's enriched interpretation (e.g. recognizing a Uniswap swap or Aave deposit) rather than just raw blockchain data.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified network
- Unsupported network returns an error
- Payment failure due to insufficient USDC balance for x402 micropayment
- Rate limiting or timeout on heavy transaction decoding
