Overview

Use this endpoint to call the Kling Video To Audio workflow through DeerAPI. The API reference on this page shows the request schema, response schema, authentication requirements, and runnable examples for the configured endpoint.

​
Before you start

Use the DeerAPI base URL and pass your API Key in the Authorization header: 
https://api.deerapi.com

Authorization: Bearer $DEERAPI_KEY

​
Model selection

Choose a current model ID from the live pricing page. Model availability changes over time, so avoid copying a model ID from an old project without checking the live list first.

​
Implementation notes

  • Use the OpenAPI playground for the exact request fields accepted by this endpoint.
  • Keep API Keys on the server side when you build production applications.
  • Log the request ID from failed calls so support can investigate the request.
  • Retry 429, 500, and 503 responses with exponential backoff.
