lauf.halowerk.com
Loads one https page in a real headless browser and performs up to eight steps on it: click, fill, select, check, uncheck, wait, wait_for_selector. Returns a per-step log saying what was attempted and whether it succeeded, plus the final URL, title, visible text, links, form structure and an optional screenshot as a base64 PNG. Three limits are part of the product, not accidents.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Three limits are part of the product, not accidents. robots.txt is fetched and evaluated before the page is loaded, following RFC 9309 precedence, and a disallowed path is refused rather than fetched; an unreadable robots.txt counts as a refusal, not as permission. Login walls, captchas and paywalls are detected and the call is aborted instead of worked around. And a step cannot navigate: the only address loaded is the one in url, so this endpoint cannot be steered somewhere else by a step list. Nothing is charged when a call is refused for any of those reasons. Not suitable for pages that require a session, and not a crawler: one page per call.",

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 18 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

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/browser-task, 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.
