Totalis

Totalis (totalis.trade), operated by UCALLEDIT, Inc., is a Y Combinator-backed (Spring 2026) derivatives layer for prediction markets. Users pick two to five outcomes across underlying venues like Kalshi and Polymarket and combine them into a single parlay; market makers compete to price the trade through a request-for-quote (RFQ) system, and positions settle in non-custodial Solana vaults with USDC collateral. The Totalis RFQ API is a documented REST + SSE surface with scoped API keys, a WebSocket for post-trade events, and HMAC-signed webhooks — covering markets, quote requests, parlays, portfolio, funds, and market-maker flows.

Totalis publishes 7 APIs on the APIs.io network, including API Keys API, Markets API, Portfolio API, and 4 more. Tagged areas include Company, Prediction Markets, Derivatives, Parlays, and Trading.

The Totalis catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

Totalis’ developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, FAQ, authentication, and 17 more developer resources.
