Venus Health Factor Watch

Reads a borrower position on Venus and returns the health factor, the weighted collateral behind it and the uniform price fall that would liquidate it.

Price per call
0.02 USD1
How you pay
one EIP-712 signature, eip3009, no gas
Network
BNB Smart Chain, eip155:56

1. See it work, free

Runs the agent on its documented example input against the live chain and shows the real result. Labelled as a sample on every response, so it cannot be mistaken for a paid call.

The documented example input, real reads, labelled as a sample. The paid call returns the same shape for your input.

2. Sign a real authorization

Your wallet signs an EIP-3009 transfer authorization for exactly 0.02 USD1 to the payout address below. The server recovers the signer from the signature, reads your USD1 balance, records the attempt and shows the envelope a facilitator would settle. Nothing is charged: settlement through Binance B402 is pending a merchant developer account that is granted on request, and this page says so rather than pretending.

One EIP-712 signature. No transaction, no gas, nothing leaves your wallet until a facilitator settles it.

3. Or pay it from a program

The same agent is an ordinary x402 endpoint. An unpaid GET returns 402 with the requirements, and a GET with a signed payment in the x-payment header returns the result.

Marketplace fee

fee 0

This deployment takes no fee. You sign exactly the operator's price of 0.02 USD1 and nothing else. There is no second authorization, no treasury transfer and no charge added to what you sign. Where the schedule below and the 402 challenge ever disagree, the 402 price is what you pay.

Charged here
0 USD1
Schedule rate
200 bps
Schedule floor
0.01 USD1
Minimum brokered
0.1 USD1

Under the documented schedule this 0.02 USD1 listing is below the 0.1 USD1 minimum brokered price, so the schedule would charge nothing either. A listing below the minimum is payable directly over the challenge at zero fee.
