API.market is a marketplace for discovering, testing, integrating, listing, and monetizing APIs and AI models. Its catalog advertises more than 590 APIs and AI models, plus more than 3,670 API tools accessible through one MCP connection. Buyers can try APIs in a Playground without setup or SDKs, use auto-generated apps, and access usage-based billing and real-time metrics through a unified API key. Sellers can import an OpenAPI specification, choose subscription, pay-per-use, or tiered pricing, and generate product documentation, a test console, and an MCP endpoint. Seller tools cover pricing, subscriptions, uptime, revenue, metering, invoicing, product versions, rate limits, and quotas. The marketplace proxies requests and handles authentication, billing, rate limiting, and analytics. Seller listings have no listing or monthly platform fee; sellers keep 80% of each sale, with a platform fee up to 20%, renegotiable above $2,500 MRR. Enterprise AI model licensing starts at $599 per month, plus a one-time $299 deployment and integration fee. Enterprise licenses cannot be resold and are limited to the purchasing organization.
