Verifies whether a specific on-chain transaction actually paid a given address, returning ERC20 transfer details, token totals, native value, confirmation depth, and minimum-threshold checks.

How this service works
Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.
Output
Returns a breakdown of every ERC20 token transfer that reached the specified address in the transaction, per-token totals, any native (ETH/BNB) value transferred, a flag indicating whether a specified minimum was met, the transaction success or revert status, and the number of block confirmations. Transactions not found on the specified chain are rejected before any charge is applied.
Example use cases
Confirm customer crypto payment received
“A customer says they paid me in USDC on Base — the tx hash is 0x4f2a...8b9c and my receiving address is 0x742d35Cc6634C0532925a3b844Bc454e4438f44e. Can you verify the payment actually arrived and was at least 50 USDC?”
Release order after on-chain payment check
“Before I ship this order, verify that transaction 0x9e1c...33fa on Ethereum actually paid 0xAbCd...1234 with at least 100 USDC — and confirm the transaction wasn't reverted and has enough confirmations.”
Audit past BNB Chain payment
“I need to audit a BNB Chain transaction from last week — hash 0xde4a...7701 — and find out exactly which tokens and how much native value were sent to 0x1234...abcd, and whether the transaction succeeded or reverted.”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/payment-verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically confirm that a specific blockchain transaction actually delivered funds to a target address on Ethereum, Base, Arc, or BNB Chain. It is preferable over generic block explorers when you need a structured, machine-readable result including ERC20 transfer enumeration, token totals, minimum-threshold checks, and confirmation depth — all in a single call. Ideal for payment gating, order fulfillment automation, or audit workflows where a yes/no payment confirmation with detail is required.
Side effects
- Transaction hash not found on the specified chain — request rejected with no charge
- Invalid or malformed transaction hash (not 64-char hex) — schema validation error
- Invalid recipient address format (not a valid 0x address) — schema validation error
- Token address provided but no minimum, or minimum provided without token — may produce unexpected results
- Transaction found but recipient address received zero transfers — minimum-not-met result returned
- Chain not supported or wrong chain specified for the transaction — request refused
