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.

"description": "Use when an agent needs the lowest listed price among models meeting hard needs (context, price cap, capability), plus a fallback reading. Pre-flight reading: the AI model with the lowest listed price on OpenRouter among those meeting your needs (min_context, max_input_per_1m, max_output_per_1m, max_job_cost_usd, capability, vendor, exclude_vendor), plus the next-lowest reading from a different vendor (fallback), with reasons, the excluded-count per filter and every formula (standard job = 10,000 input + 1,000 output tokens). Skips variable-price, free-tier (unless include_free=true), soon-retiring and currently disturbed vendors. A price measurement, not advice and not a quality rating. JSON.

Show the promptHide the prompt
Using Roundhouse, look up the x402 service Agent Weather 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=Agent%20Weather' 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://api.agentweather.io/v1/decide/cheapest-model, 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. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
