Given a Polymarket market (slug, URL or conditionId; Kalshi ticker supported), reads the rules clarification (Additional context) from the UMA adapter on Polygon, finds the real-world outcomes whose resolution changed, shifts fair probability by their verified, ensemble-estimated mass, walks the live CLOB book at your size after fees and slippage, and returns BUY_YES / BUY_NO / EXIT / HOLD / NO_MATERIAL_CHANGE with fractional-Kelly sizing.

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 agents.writerslogic.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=agents.writerslogic.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://agents.writerslogic.com/api/v1/clarification-impact, 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.
