HALOWERK defiwerk
Resolves pool, price oracle and data provider through the protocol address provider rather than hard-coded addresses, then reads every reserve the wallet touches: collateral amounts, variable and stable debt, LTV, liquidation threshold, liquidation bonus and the borrow rate, all at one block. Values are computed with the price the protocol oracle reports, not with a market price from an exchange — a liquidation follows the oracle, and the oracle source contract per asset is named in the answer s

0x2880EdfFF13100677Bf97A3CBdF3Bc34771C4E5EThe wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

Provider
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Values are computed with the price the protocol oracle reports, not with a market price from an exchange — a liquidation follows the oracle, and the oracle source contract per asset is named in the answer so it can be cross-checked with the oracle endpoint of this hub. liquidation_price is given per collateral asset as the oracle price at which the health factor reaches one while all other prices hold; where a single asset cannot trigger it even at price zero, the field says so instead of showing a number. Scenarios apply a uniform fall to all collateral while debt stays nominal, and that assumption is printed with them. Reads only: no transaction, no signature, no advice on whether to add collateral or close. Positions on protocols other than the ones listed are rejected rather than approximated.",

Using Roundhouse, look up the x402 service HALOWERK defiwerk and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=HALOWERK%20defiwerk' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://defi.halowerk.com/lending/health, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
