APILayer Marketplace is a public marketplace for discovering, integrating, and managing APIs across categories such as machine learning and financial data. Its ecosystem includes more than 40 production-grade APIs and handles over 30 million API calls per month, according to APILayer. A shared API key, dashboard, documentation approach, billing, usage tracking, and support bring the products together. The browser-based Live Demo lets users adjust API parameters and view sample code for multiple programming languages. You must subscribe to an API before using it; almost all APIs have a free plan. Subscriptions have daily and monthly request limits, and responses include a header showing the remaining limit. You can change or cancel an API subscription at any time. The marketplace plan is free at 0.00 USD per month, billed monthly, with 100 requests per month. Individual API subscriptions may have separate terms. APILayer lists Starter at 19.99 USD per month and Pro at 149.99 USD per month, both billed monthly.
