## 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 x402-dellbot-win-d7a5615d -d '<json body>'
```

Example prompt: Send this to the cheapest available LLM on the x402 Bazaar using Llama 3.3 70B with streaming enabled: 'Explain the difference between TCP and UDP in two sentences.' Use tool calling if needed.

## When to prefer this

Choose this endpoint when cost is the primary concern and the task does not require frontier-tier reasoning. Ideal for high-volume, low-stakes completions, simple Q&A, summarization, or tool-calling workflows where $0.001/call economics matter. Prefer over mid-tier or pro endpoints when Llama 3.3 70B, Mistral Small, Gemma 3 27B, or similar open-weight models are sufficient. Avoid when deep reasoning, very long context, or state-of-the-art code generation is needed.

## Known failure modes

- Payment failure: x402 micropayment not accepted or insufficient USDC balance
- Model not found: specified model name not available on this endpoint
- Invalid request format: messages array missing or malformed, returns 400
- Tool schema invalid: malformed function definitions cause completion failure
- Streaming error: SSE connection dropped mid-response
- Rate limit or capacity: 503 if Venice AI backend is overloaded

## How this service works

Cheapest LLM on CDP x402 Bazaar. OpenAI-compatible chat completion. Default OpenAI GPT-OSS 120B; also offers Llama 3.2 3B, Mistral Small 24B, Gemma 3 27B, Qwen3.5 9B, and Nemotron Nano 30B (all via Venice AI). 512-token output cap, 6000-char input cap. Supports tools/tool_choice and stream:true SSE.

## Output

An OpenAI-compatible chat completion response containing the assistant's generated message, or a stream of SSE chunks if stream:true is set. May include tool_calls if tools were provided and the model chose to invoke one. Charged $0.001 USDC per call via x402 payment protocol.
