Hosted Kalshi and Polymarket reads for scripts and agents
What it is
A hosted read API for Kalshi and Polymarket, offered over HTTP, a command-line tool, an SDK, and an MCP server. Callers can pull live markets and search results, screen contracts on indicators such as implied yield, liquidity, and time decay, and request a regime label for whether a book looks maker-favorable or taker-favorable. Funds, desks, and developers building agents on prediction-market odds are the audience. Authenticated reads on the free plan share a monthly request ceiling and a per-minute burst limit, host-paid model calls spend a separate token budget, and a direct call to the venue itself is outside this meter.
