1xAPI is an API marketplace that helps developers discover, test, and integrate production-ready services through a single platform. Its current offerings include Email Verify Pro, which checks email validity using MX and SMTP verification and detects disposable addresses, and Football Live Streaming, which provides live match streams, fixtures, scores, and league data across the EPL, La Liga, Serie A, and more than 50 other leagues. Developers can sign up for free, generate an API key, and connect to services with a single API call; free tiers are available, with options to scale as usage grows.

Built on Cloudflare’s global edge network, 1xAPI highlights fast delivery, security features, and reliability. The platform also serves API publishers, who can connect an existing endpoint, choose free, usage-based, or monthly pricing, and earn revenue from subscriptions. 1xAPI handles functions including authentication, billing, rate limiting, and global delivery, while providing analytics for usage, revenue, errors, and latency.

Its Hub, Publisher Studio, and developer resources bring API discovery and publishing together in one place
