The RapidAPI Marketplace API turns the RapidAPI catalog into structured data. It searches public API listings and returns the pricing model, category, popularity score, reliability metrics, and publisher, with billing plans and ratings in detailed mode. One JSON row per listing, no RapidAPI account, login, or key required.

API discovery should be a query, not thirty open browser tabs. Point the Actor at a category and get the whole field as one sortable dataset, so you can shortlist candidates on real numbers instead of marketing pages, size a niche, or watch your own competitive space over time.

What each row returns

• title, name, description, and the listing url

• pricing model: FREE, FREEMIUM, or PAID

• popularityScore from 0 to 10, with avgLatency and avgSuccessRate

• detailed mode adds billingPlans, subscriptionsCount, ratingScore, and ratingVotes
