Overview

Payment verification on Ethereum, Base, Arc or BNB Chain: did this transaction really pay this address? Pass ?hash=&to= (and optionally &token=&min=) and get every ERC20 transfer that reached the address, the totals per token, any native value, whether a minimum was met, success or revert, and how many blocks deep it is. A hash not mined on that chain is refused before any charge.

Endpoint

Method	Endpoint	Price	Description
GET	/v1/marketplace/api/payment-verify	$0.00115	Invoke Payment Verify (Blockchain) and return the upstream response.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/payment-verify

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/payment-verify
