## 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 deepseek-llm-inference-via-x402-3a4c0bbe -d '<json body>'
```

Example prompt: Can you use the DeepSeek LLM to answer this in Chinese: '请解释量子纠缠的基本原理，并用简单的例子说明它的应用。'

## When to prefer this

Choose this endpoint when you need LLM inference optimized for Chinese-language content or very long contexts, and you want to pay per request without committing to an API key or subscription. It is ideal for agents operating in multilingual environments, handling Chinese text, or processing lengthy documents where other models may hit context limits. The x402 micropayment model makes it suitable for low-frequency or one-off inference tasks.

## Known failure modes

- Payment not included or insufficient USDC — request rejected with 402 Payment Required
- Malformed input schema — missing or invalid 'input' field returns an error
- Context length exceeded for very long inputs beyond model's maximum window
- Service unavailable due to upstream DeepSeek API outage
- Rate limiting or throttling under high load on the worker gateway

## How this service works

Chinese & long-context optimized LLM inference via x402. Pay per request, no API key.

## Output

Returns a chat completion response containing the model-generated text output in response to the provided input prompt, following standard OpenAI-compatible chat completions format.
