Apily

Apily is a multi-provider API platform that lets developers reach leading models through one API key and one billing account. Key features: • One API key for supported leading models • OpenAI-compatible and Anthropic-compatible endpoints • Usage-based billing with a prepaid balance • Switch models without rebuilding your integration • Compare current usage prices across providers. Instead of maintaining a separate key, billing flow, and integration for every model provider, you connect once to a single endpoint and choose the models your product needs. Pay only for the usage you generate, which keeps infrastructure costs predictable and easier to control as traffic grows. Apily works with many popular coding assistants, chat interfaces, and agent frameworks that support OpenAI-compatible or Anthropic-compatible APIs, so your existing tools can connect with minimal changes. Built for developers and AI product teams who want lower model costs, fewer accounts to manage, and the flexibility to change providers as the market evolves. Ideal for SaaS builders, startups, and engineering teams shipping customer-facing features, internal tools, or developer utilities that depend on multiple models.
