BYOK (bring your own key) — Connect providers you already use (OpenAI, Together, OpenRouter, or any OpenAI‑compatible endpoint). You pay your provider; Paywalls bills your users.

​
Model selection & routing

  • You choose a model id (e.g., openai/gpt-4o-mini, openrouter/llama-3.1-70b). We normalize requests and route to the right upstream.
  • You can mix providers across requests while keeping one pricing surface.
  • Fallbacks and failover depend on provider capabilities.
