How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object with the transaction hash, status (ok/fail), block number, network, sender address, contract selector, native asset symbol (e.g. ETH), native value and fee in ETH, total event count, an array of token transfers (each with from/to addresses, token contract, amount, symbol, and raw gross amount), an array of NFT transfers, and a block explorer URL.
Example use cases
Verify USDC payment on Base
“I need to confirm that transaction 0x9de0044cbae3b8df09402ca5a6ac348c307e68918216a0b2d35133811bef03b8 on Base actually sent USDC — can you check the token transfers and status for me?”
Audit ERC-20 transfers in an Ethereum tx
“Look up Ethereum transaction 0xabc1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcd and list every ERC-20 token transfer that happened, including amounts and symbols.”
Investigate on-chain activity for a wallet
“There's a suspicious transaction on Arbitrum with hash 0xdef0987654321fedcba0987654321fedcba0987654321fedcba0987654321fedc — can you pull all the token and NFT transfers, who sent them, and how much gas was spent?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/tx-transfers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need complete transfer-level details for a single EVM transaction across Base, Ethereum, Arbitrum, Optimism, or Polygon — including token transfers, NFTs, gas fees, and status — paid per-call in USDC without a subscription. Prefer it over block explorer UIs when you need structured, machine-readable output for agent workflows, payment verification, or on-chain audit tasks.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction not found on the specified network
- Network not specified or defaults may not match the actual chain the tx is on
- Hash belongs to a different chain than the one specified
- API returns null fields if the transaction is still pending or unconfirmed
