How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.
Output
Returns structured on-chain transaction data for the specified hash on the chosen chain (Base, Ethereum, or Solana), including transaction status, amounts, sender/receiver addresses, and other chain-native metadata.
Example use cases
Verify x402 payment on Base
“Check if this Base transaction 0x9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e went through and confirm it was a valid USDC payment.”
Confirm Solana transfer completion
“Look up this Solana transaction signature 5J3mBbAH538GdXN9imWTWDMQyFjY1bBDkXx8sFhgwMCpEYdRoBWHZCj7k and tell me whether it succeeded and what was sent.”
Audit Ethereum transaction history
“Fetch the details of Ethereum transaction 0xabc123def456abc123def456abc123def456abc123def456abc123def456abcd — I need to know the sender, receiver, and value transferred.”
Technical details
Endpoint
POSThttps://data.tollkit.dev/chain/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-as-you-go blockchain transaction lookup with no account or API key setup — ideal for agents that need to verify or audit individual transactions on Base, Ethereum, or Solana without committing to a subscription. Best when the agent already holds USDC on Base or Solana and wants frictionless per-call access.
Side effects
- Invalid transaction hash format returns a validation error
- Transaction hash not found on the specified chain returns a not-found error
- Wrong chain specified for a given hash (e.g. Base hash queried on Solana) returns no result
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Network congestion or RPC downtime may cause timeouts
