Use this endpoint for Gemini streaming text generation and incremental event output.
  • The common auth pattern is x-goog-api-key: {API_KEY}, though query-string API keys are also supported
  • The request structure is mostly the same as generateContent, with contents as the core field
  • The response is an event stream rather than one final JSON payload
  • Finish state and safety metadata may only become complete in later chunks
