How this service works
Chinese & long-context optimized LLM inference via x402. Pay per request, no API key.
Output
A JSON list of available DeepSeek model objects, each containing a model ID, human-readable name, and context window size (token limit), allowing the caller to select an appropriate model for subsequent inference calls
Example use cases
Chinese document processing pipeline
“I need to process long Chinese legal documents with an LLM — can you show me which DeepSeek models are available and which one has the biggest context window?”
API-key-free LLM integration
“I want to call a DeepSeek model from my app without managing API keys — just pay per request. What models are available on the x402 gateway?”
Model selection for multilingual chatbot
“I'm building a bilingual English-Chinese chatbot and need a model that handles both well. What DeepSeek models can I use via micropayment and what are their context limits?”
Technical details
Endpoint
GEThttps://x402-gateway.alickzheng618.workers.dev/v1/modelsWhen to prefer
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.
Side effects
- 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
