APEX X1 Payment Verification is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).
Verifies whether an X1 (Solana-based) transaction signature represents a completed payment, returning payer, amount received, confirmation status, and whether the expected amount was met.

How this service works
Did that X1 payment actually land? Pass ?sig=<signature> and optionally ?to=<wallet>, ?mint=<token> and ?expect=0.5 to get the payer, how much reached that wallet in XNT or any SPL token, whether it covers what you expected, confirmed vs finalized, memos, fee and slot. Counted by balance change, so a payment sent by a program (escrow, multisig, router) is seen too. Read-only: checking never consumes the payment.
Output
Returns the payer's wallet address, the amount received (in XNT or specified SPL token), whether the received amount meets the expected threshold, confirmation and finalization status, any transaction memo, the fee paid, and the slot number. Works for payments sent via programs like escrow, multisig, or routers.
Example use cases
Merchant payment confirmation at checkout
“I need to confirm that the customer's X1 payment arrived before releasing their order — the transaction signature is 4mZp9...bT3v and I expected 1.25 XNT at my wallet G5Kj...nR8x, did it land?”
SPL token payment verification
“Can you verify this X1 transaction signature 2nXq7...vL4k paid out at least 50 USDC tokens (mint EPjF...Dt1v) to my wallet 9sRm...wK2p?”
Program-routed escrow payment check
“An escrow smart contract was supposed to release 2 XNT to my wallet 8tYq...cJ5n — the transaction signature is 5pLw3...dM7b, can you confirm the payment landed and whether it's finalized yet?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/x1-payment?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify a payment on the X1 (Solana-compatible) network by transaction signature, especially when the payment may have been routed through a program (escrow, multisig, router) rather than a direct wallet transfer. Prefer this over generic block explorers when you need a structured, machine-readable answer about whether a specific amount reached a specific wallet.
Side effects
- Invalid or malformed base58 signature returns an error
- Transaction not yet propagated to the network returns unconfirmed or not found
- Wrong mint address returns zero token balance for that token
- Signature exists but is not a payment transaction returns empty or zero amount
- Network timeouts if X1 RPC is slow or congested
