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 full transaction details including the hash, sender address (from), recipient address (a), block number, transaction type, nonce, value transferred, native currency symbol, network name, chain ID, pending status, function selector, input data, gas limit, gas price in gwei, max fee in gwei, and max priority fee in gwei.
Example use cases
Verify DeFi swap transaction details
“I just did a swap on Base and want to confirm it went through — can you pull up transaction 0x9de0044cbae3b8df09402ca5a6ac348c307e68918216a0b2d35133811bef03b8 and tell me the block it landed in, whether it's still pending, and what the gas price was?”
Audit smart contract call on Ethereum
“Can you look up Ethereum transaction 0xabc123... and decode what function selector was called, who the sender was, and what the input data contains?”
Check cross-chain transaction on Arbitrum
“I need to verify a transaction on Arbitrum — hash is 0xdef456... — can you check if it's confirmed, what block it's in, and how much ETH value was transferred?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/evm-transaction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, decoded on-chain transaction data for EVM-compatible networks (Base, Ethereum, Arbitrum, Optimism, Polygon, BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain) and want gas details, sender, block, and input data in a single call without running your own node. Pay-per-call at $0.003 USDC via x402 makes it ideal for agents that need occasional transaction lookups without a subscription.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on the specified network
- Unsupported network name causes validation error
- Network mismatch — hash exists on a different chain than specified
- RPC timeout or node unavailability for specific chain
