OpenClaw Custom API Setup: Run GLM, Kimi, and DeepSeek Without the Frontier Price Tag

OpenClaw offers a flexible solution for integrating custom APIs, enabling users to connect any OpenAI API-compatible interface as a custom provider, thus allowing the use of cost-effective open-source models instead of expensive cutting-edge ones. This setup can significantly reduce token costs, potentially saving over 70% on routine tasks while maintaining similar performance. The process involves defining providers in the models.providers section and whitelisting models in agents.defaults.models, a crucial step often overlooked that can lead to configuration errors. OpenClaw's customization not only reduces costs but also provides stability and compatibility for teams outside certain service areas, enabling a unified endpoint for multiple agents like Claude Code and Codex through Atlas Cloud, simplifying management and billing. The configuration requires understanding the separation between provider definition and model whitelisting, which can be efficiently handled using the openclaw onboard wizard, or manually with JSON file edits, ensuring that the setup aligns with specific project needs and budget constraints.
