Opper AI

About

A single API key grants access to over 300 models, all hosted within the European Union. It is fully compatible with the OpenAI, Anthropic, and Google SDKs, requiring only a change to the base URL for integration. Key distinctions include the fact that roughly half of our more than 30 providers perform inference in Europe, a single EU sub-processor manages every model, and prompts are not stored by default. Gain additional oversight with features for intelligent routing, PII masking, team-specific spending limits, and audit logs. Designed for agents, it integrates seamlessly with tools like Claude Code or Cursor using a single line of code to configure Opper automatically. There is no markup on tokens, with only a 3 percent fee applied to credit top-ups.
