## 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-x402-3e013180
```

Example prompt: What DeepSeek models are currently available for inference — I want to pick one that supports long Chinese-language documents without needing to set up an API key?

## When to prefer this

Choose this endpoint when you need to discover which DeepSeek models are available before making an inference call, especially if you want long-context or Chinese-language-optimized LLMs without managing traditional API keys. Ideal for agents using x402 micropayment flows where pay-per-request billing is preferred over subscriptions. Prefer this over OpenAI or Anthropic model listings when Chinese language performance or DeepSeek-specific capabilities are the priority.

## Known failure modes

- Payment not provided or insufficient — x402 payment required before response is returned
- Invalid x402 payment header — gateway rejects malformed micropayment credentials
- Network timeout from Cloudflare Workers edge — retry with backoff
- No models currently available — empty list returned if backend is unreachable
- Rate limiting on the worker — too many rapid requests may be throttled

## How this service works

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

## Output
