History

APILayer started with a simple observation: developers were spending more time vetting, integrating, and managing third-party APIs than actually building their products. Every new data source meant a new provider, a new auth flow, a new billing relationship, and a new set of documentation to learn. APILayer was created to fix that. What began as a small collection of data APIs, including early products like Currencylayer and IPstack, has grown into a curated ecosystem of 40+ production-grade APIs serving 2.2M+ developers and engineering teams worldwide. Today, APILayer handles 30 million+ API calls per month across a global infrastructure. The platform is used by solo developers prototyping their first app and by enterprise engineering teams running mission-critical systems in fintech, e-commerce, SaaS, and beyond. APILayer is part of the broader Idera, Inc. family of developer tools.
