How this service works
OpenAI-compatible chat completions on DeepSeek V4 Flash, fast and inexpensive frontier model with tool calling and a 1M-token context. Set your OpenAI SDK base URL to https://agentrxi.com/v1/deepseek and pay per token with x402 instead of an API key: $0.88 per million input and $2.64 per million output tokens, minimum $0.002 a call, at most $0.0740. The 402 quotes your request's maximum; "upto" payers are charged only the tokens used. Same request/response shape as OpenAI (to
Output
Returns an OpenAI-compatible chat completion JSON object containing the assistant's reply text, finish reason (e.g. 'stop'), model name ('deepseek-v4-flash'), and token usage breakdown (prompt, completion, total tokens).
Example use cases
Quick translation for agent pipeline
“Translate this sentence into French using DeepSeek Flash, keep it under 50 tokens: 'The payment was processed successfully.'”
Structured data extraction from text
“Use DeepSeek to extract the company name, date, and total amount from this invoice text and return JSON: 'Acme Corp, Invoice #1042, Due March 15 2025, Total: $4,200.'”
On-the-fly code explanation
“Have DeepSeek V4 Flash explain what this Python function does in plain English, max 150 tokens: 'def fib(n): return n if n <= 1 else fib(n-1)+fib(n-2)'”

Endpoint
GEThttps://agentrxi.com/v1/deepseek/chat/completions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap LLM inference from DeepSeek V4 Flash without committing to a subscription or API key — ideal for agent pipelines that want micropayment-per-call billing in USDC via x402. Prefer this over Llama 3.3 70B on AgentRXI when speed and cost matter more than reasoning depth, and over OpenAI-based endpoints when you want to avoid API key management entirely.
Side effects
- Missing required 'prompt' query parameter returns a 400 error
- Insufficient USDC balance or failed x402 payment returns a 402 Payment Required
- Exceeding max_tokens limit may truncate the response with finish_reason 'length'
- Invalid temperature value (outside 0–2) may cause a 422 validation error
- Model unavailability or upstream DeepSeek outage returns a 503 or 500 error
