Per-market liquidity authenticity + UMA resolution-risk for Polymarket prediction markets, sold to AI trading agents via x402 ($0.20/call, USDC on Base).

Dispute-rate and flip-rate often invert by category - a two-axis read no other tool gives. Fact/base-rate, never a wash verdict nor per-market prediction. Also two /market-authenticity/{conditionId} and /x402-authenticity/{payTo} parameterized endpoints (see /openapi.jso

Live probe hasn't run yet.
fail Protocol version 0/10
No protocolVersion in card.
How to earn +10 points

41/45 probes succeeded (91% uptime).
How to earn +1 point
Stabilise uptime
We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

fail Skill declaration 0/10
No skills declared in card. Hard to route to.
How to earn +10 points
Declare your skills
Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.
