About API.market
API.market is a marketplace where developers can buy and sell APIs and AI models. The catalog lists more than 1,380 APIs across categories such as image editing and generation, video, AI models and inference, developer tools, security, data and web intelligence, business APIs and text analysis. Examples include flight data, face swap, text-to-video, routing, geocoding, web scraping, email validation and job search APIs. Requests are made with an API key, and each listing shows ratings, reviews, usage counts and its own pricing.
For AI agents, API.market offers a single MCP connection that the site says gives agents access to more than 6,210 API tools for tasks like generating images, scraping web pages, searching flights and creating videos. A set of no-code AI apps lets non-technical users generate images, create videos and transform content in a few clicks.
The site states it is used by over 19,000 developers and handles more than 151 million API calls per month, with 99.9% uptime. Third-party providers can list their own APIs through a seller console.
