Two-Way De-vig
De-vig a two-way market into fair probabilities that sum to 1. Call when recovering fair probs from a two-outcome book with overround. Returns fair yes/no probs after proportional de-vig as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
