CallingBox is an API-first product. Every SDK and tool is a thin layer over the same public /v1 API. Use the API directly if you want raw HTTP. Use an SDK when you want faster setup, typed responses, and a language-native workflow.

What the SDKs handle for you

  • Authentication with your API key
  • JSON request building for agents, calls, and numbers
  • Typed response objects instead of raw dictionaries
  • Cleaner workflows for polling, pagination, number management, and agent attachments
  • Language-native naming (for example Python uses from_ instead of from, and agent_id/primary_number_id; TypeScript uses agentId/primaryNumberId)
