lauf.halowerk.com
Loads a public https page, finds the requested form, fills your values into it in a real headless browser and reports what a submission would run into — without submitting. Each field is checked against what the page itself declares: whether it is required and empty, whether the value matches the field type for email, url, number, tel, date, time and color, and whether a select value is one of the offered options.

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.

Each field is checked against what the page itself declares: whether it is required and empty, whether the value matches the field type for email, url, number, tel, date, time and color, and whether a select value is one of the offered options. Fields you named that the form does not have are reported, as are required fields you left out. The promise not to submit is structural, not a policy: the input schema has no place to put a selector or a click, and the only browser steps this endpoint generates are fill, select and check on fields that exist in the loaded form. It never clicks, and it never presses a key. One thing it cannot prevent and therefore states plainly: a page whose own script submits on input will do so regardless of who typed. What it cannot do is run the page own JavaScript validation — a site that checks values in script may still reject a value this endpoint calls plausible, and that limit is stated rather than papered over. robots.txt is honoured; login walls, captchas and paywalls end the call instead of being worked around, and a refused call is not charged.",

Using Roundhouse, look up the x402 service lauf.halowerk.com 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=lauf.halowerk.com' 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://lauf.halowerk.com/v1/form-dryrun, 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.
