APILayer Marketplace vs Azure API Center

APILayer Marketplace is a public web and API platform for discovering, integrating and managing APIs across categories such as machine learning and financial data. APILayer describes a catalog of more than 40 production-grade APIs with one API key, a shared dashboard and consistent documentation. The browser-based Live Demo lets users change parameters, try requests and view sample code in several programming languages. The platform combines subscription billing, usage tracking and support, and responses include a header showing remaining limits. Users must subscribe to an API before using it; almost all APIs have a free plan. Subscriptions can be upgraded, downgraded or canceled without a long-term commitment. Plans include Free Plan at free, billed monthly, with 100 requests monthly; Starter Plan at $19.99 a month; and Pro Plan at $149.99 a month. APILayer targets individual developers and enterprise teams in fintech, e-commerce and SaaS.
