How this service works
OpenAI-compatible chat completions on DeepSeek V4 Pro, a top open frontier model with reasoning, tool calling and a 1M-token context. Set your OpenAI SDK base URL to https://agentrxi.com/v1/deepseek-pro and pay per token with x402 instead of an API key: $2.64 per million input and $7.92 per million output tokens, minimum $0.002 a call, at most $0.2158. The 402 quotes your request's maximum; "upto" payers are charged only the tokens used. Same request/response shape as OpenAI
Output
Returns an OpenAI-shaped chat.completion JSON object including the assistant's message content, role, finish reason (e.g. 'stop'), token usage (prompt, completion, total), model name, and a completion ID.
Example use cases
Complex reasoning on a technical question
“I need a thorough, step-by-step reasoning breakdown of why quicksort has O(n log n) average complexity — ask DeepSeek V4 Pro and give me up to 800 tokens in the response.”
Multilingual content drafting
“Use the DeepSeek model to write me a professional cold email in French introducing our analytics SaaS to a potential enterprise client — keep it under 300 tokens.”
Code generation with large context
“Paste this 10,000-line Python codebase into DeepSeek V4 Pro and ask it to identify all functions that have no unit test coverage, then suggest what tests to write — use a system prompt saying 'You are a senior software engineer.'”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/deepseek-pro/chat/completions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a high-capability frontier LLM with a 1M-token context window, reasoning, and tool-calling support, without managing an API key or subscription — especially when you want pay-as-you-go per-token billing via x402 micropayments and an OpenAI-SDK-compatible interface. Prefer it over OpenAI's endpoint if you want DeepSeek's reasoning model at a lower per-token cost, or when your use case requires extremely long contexts.
Side effects
- Insufficient x402 payment or wallet balance causes 402 rejection before inference begins
- prompt or system message exceeds the 1M-token context limit causing a 400 error
- max_tokens set too low resulting in a truncated response with finish_reason 'length'
- Temperature out of valid range (e.g. negative or very large) may cause a 400 validation error
- Network timeout on very long reasoning completions
