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. Auth is a Bearer API key or an x402 wallet (SIGN-IN-WITH-X); see venice-auth.

Use when

• You need LLM text generation, with or without tools, with or without streaming.
• You want multimodal inputs (images, audio, video, documents) to a capable model.
• You want Venice-specific features: web search, web scraping, citations, E2EE, characters, xAI X/Twitter search, thinking control.
• You need prompt caching for large system prompts or long documents.
• You need structured (json_schema) output.

For the OpenAI Responses-style shape (typed output[] blocks), see venice-responses. To pick a model, see venice-text-routing.
