# AiSpace Chat Completions (Venice.ai)

> AiSpace Chat Completions (Venice.ai) is a paid API for AI agents from x402.aispace.bot, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Sends a chat completion request to AiSpace's privacy-focused AI chat API powered by Venice.ai, returning an AI-generated response.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aispace-chat-completions-venice-ai-ec2dcdb3 -d '<json body>'
```

Example prompt: Using AiSpace's Venice-powered privacy AI, send these messages to the qwen3-5-9b model and get a completion: system message 'You are a helpful assistant' and user message 'Explain quantum entanglement in simple terms.'

## When to prefer this

Choose this endpoint when privacy is a primary concern and you need AI chat completions without server-side data retention, powered by Venice.ai's uncensored models. Prefer it over mainstream OpenAI or Anthropic APIs when you want a pay-per-call micropayment model (via x402/USDC) and compatibility with Venice's model lineup including Qwen variants.

## Known failure modes

- Payment not processed — x402 payment of $0.001 USDC required before response
- Missing required 'messages' query parameter returns validation error
- Missing required 'model' parameter results in bad request
- Invalid model name returns error or fallback behavior
- Streaming flag set to true may require SSE handling
- Schema quirk: parameters appear in queryParams rather than request body, which may cause integration confusion
- Venice.ai backend downtime causes 503 or timeout

## How this service works

OpenAI-compatible chat on 100+ Venice models via x402 USDC (Base). Model from GET /api/v1/models?type=text; personas via /characters. Thinking models: empty content + reasoning_content is success; use venice_parameters.disable_thinking for plain text.

## Output

Returns a JSON object confirming success (ok: true) along with the AI-generated chat completion text from the selected model. The response follows a standard OpenAI-compatible chat completions format.
