Polymarket Intelligence API
Resolution Watch measures, on-chain, Polymarket/UMA resolution risk: when a market is disputed, does the answer actually change? Dispute-rate and flip-rate rank categories in opposite orders. Fact/base-rate, auditor posture, machine-readable for AI agents.

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 Polymarket Intelligence API 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=Polymarket%20Intelligence%20API' 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.polym.uk/resolution-risk, 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.
