Perp Funding Extremes
Use when hunting crowded perps: which markets have funding far from their own normal and where open interest is jumping. Input: optional limit (1-50, default 10), min_oi_usd (default 1,000,000). Output: as_of, fundingExtremes ranked by |z| (current 1h funding vs the coin's last 7 days), oiMovers24h and oiMovers1h (open-interest % change), each with funding APR and OI USD. Example: ?limit=10

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.

Using Roundhouse, look up the x402 service Perp Funding Extremes 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=Perp%20Funding%20Extremes' 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://1gateway.dev/v1/crypto/hyperliquid/extremes, 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.
