How this service works
Pay-per-call data for AI agents, paid in USDC on Base with x402: token risk checks (rug check) on Base, Ethereum, Arbitrum, Optimism, Polygon and Solana, onchain reads (balances, transactions, gas, contracts, NFTs, whale trades, new pools, ENS and Basenames), ECB exchange rates, and Canadian sales tax and business days.
Output
A structured, human-readable summary of the Arbitrum One transaction including: success/failure status, block number, block timestamp, from and to addresses, ETH value transferred, gas used, gas fee in ETH, the function method selector called, and a decoded list of ERC-20 transfers with token symbol and amount for each.
Example use cases
Verify a crypto payment receipt
“I just sent a payment on Arbitrum One and the tx hash is 0xabc123...def456. Can you confirm it went through, who it was sent to, and what token amount was transferred?”
Audit a DeFi trade transaction
“I made a swap on Arbitrum earlier — hash is 0x9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210fe. Break down the transaction for me: status, gas fee, method called, and all the ERC-20 transfers involved.”
Investigate suspicious wallet activity
“Someone flagged this Arbitrum transaction as suspicious: 0x1122334455667788aabbccddeeff00112233445566778899aabbccddeeff0011. Can you tell me the sender, recipient, ETH value, and what tokens were moved?”
Technical details
Endpoint
GEThttps://ca-tax-api-mainnet.lxtap.workers.dev/arbitrum/tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, human-readable breakdown of a specific Arbitrum One transaction without running your own node or parsing raw RPC responses. It is ideal for verifying payments, auditing DeFi trades, or investigating wallet activity on Arbitrum One specifically. Prefer this over generic block explorers when you need structured, agent-consumable data with decoded ERC-20 transfers. Choose OP Mainnet or Ethereum sibling endpoints for transactions on those chains instead.
Side effects
- Invalid or malformed transaction hash (not matching ^0x[0-9a-fA-F]{64}$) returns an error
- Transaction hash not found on Arbitrum One returns a not-found error
- Network or RPC connectivity issues may cause timeouts
- Missing required 'hash' query parameter returns a validation error
