# OyaPicks

> Cross-venue prediction-market data for AI agents, payable per request over
> x402. No API key, no signup, no subscription. Pay only for the call you make.

OyaPicks normalizes prediction-market data from Polymarket and Alpha Arcade into
one shape, so an agent can compare venues without writing per-venue adapters.
The same pipeline powers a public, independently verifiable prediction track
record at https://oyapicks.app/track.
