Do you use PydanticAI? Integrating Requesty is a super simple 3 stage process:
  • Set your Requesty API key
  • Set your Requesty base URL
  • Choose one of the 300+ supported models
And get immediate value:
  • Access to all the best LLMs
  • A single API key to access all the providers
  • Very clear spending dashboards
  • Telemetry and logging out of the box
You can use the Requesty router to access any LLM, and get cost management, monitoring and fallbacks out-of-the-box.

​
Configure via environment variables

Set: Change the model parameter to any model, and you’re done! (Yes, you can use Anthropic or any other model without changing anything but the model parameter)
