Venice Chat Completions
POST /api/v1/chat/completions is Venice's main text endpoint. It's OpenAI-compatible, plus a venice_parameters object for Venice-only features.
Use when
- You need LLM text generation, with or without tools, with or without streaming.
- You want multimodal inputs (images, audio, video) to a vision/audio-capable model.
- You want Venice-specific features: web search, E2EE, characters, xAI X/Twitter search, strip-thinking, web scraping.
- You need prompt caching for large system prompts or long documents.
- You need structured (
json_schema) output.
For the newer Alpha Responses API, see venice-responses.
