Online slot machine data: RTP, volatility, max win and features for 6,000+ games.

About slot.report

The API provides structured JSON data for over 6,000 online slot games from 80+ providers, covering fields such as RTP, volatility, max win, bonus mechanics, grid layout, paylines, and release dates. Data is sourced from official provider specifications and cross-verified against multiple industry databases, with daily updates as new releases are discovered. Endpoints cover the full slot list, a single-slot detail view, newest releases, provider listings, and API status metadata, with an OpenAPI 3.1 specification available for code generation and AI agent integration.

Access is free but requires a dofollow link to slot.report: websites are verified automatically by domain, while server apps and tools receive a domain-bound key after a 24-hour link-free trial. The link is re-checked daily, and access pauses if it is removed or set to nofollow; users registered before 2026-06-30 are grandfathered in without this requirement.

The product is aimed at developers building comparison tools, running data analysis, or training models on slot-game data. It also ships an official WordPress plugin with shortcodes and a Gutenberg block for displaying slot cards and tables without coding, plus free embeddable widgets (top RTP, newest releases, single slot card, max wins, bonus-buy, provider, and market stats) that render live data and support click-through links to a site of the embedder's choosing, again contingent on a visible dofollow link back to slot.report.
