## 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 taifoon-qwen3-235b-a22b-instruct-2507-chat-completion-a40f8ba9 -d '<json body>'
```

Example prompt: Ask Qwen3-235B on Venice AI's private inference: explain the tradeoffs between MoE and dense transformer architectures in under 300 tokens.

## When to prefer this

Choose this endpoint when you need a very large (235B parameter) mixture-of-experts model with strong reasoning capabilities and care about inference privacy (Venice AI does not log prompts on shared infra). Prefer it over smaller model endpoints on the same host when task complexity demands it, and over generic OpenAI endpoints when you want pay-per-call USDC micropayments via x402 with no subscription. The answer-before-charge model reduces financial risk for agentic pipelines.

## Known failure modes

- Insufficient USDC balance or staked DIEM — payment rejected before response is delivered
- max_tokens exceeds the 700-token ceiling — request rejected with validation error
- messages array empty or missing required role/content fields — schema validation failure
- Model name provided does not match qwen3-235b-a22b-instruct-2507 or recognized aliases — may fall back to default model
- Venice AI upstream inference outage — 502/503 returned by coordinator
- Rate limiting or credit exhaustion mid-session — partial responses or 429 errors
