How this service works
DeepSeek's flagship chat model — strong open-source reasoning and coding at low cost
Output
Returns the model-generated text response from DeepSeek's flagship chat model, including any chain-of-thought reasoning or code output depending on the prompt. The response is the direct completion from the model given the input messages.
Example use cases
Code debugging with DeepSeek reasoning
“Send this Python function to DeepSeek and ask it to find the bug and explain why it fails: def factorial(n): return n * factorial(n) if n > 0 else 1”
Low-cost open-source LLM for agent pipeline
“I need to process 50 customer support tickets using DeepSeek — for each one, classify the issue type and suggest a one-sentence reply. Use the pay-per-call API so I only pay per ticket.”
Complex multi-step reasoning task
“Use DeepSeek to work through this math word problem step by step and show all intermediate reasoning: 'If a train travels at 60 mph for 2.5 hours then slows to 40 mph for another 90 minutes, what is the total distance traveled?'”

Endpoint
POSThttps://x402engine.app/api/llm/deepseek?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DeepSeek's strong open-source reasoning and coding capabilities on a pay-per-call basis without committing to a subscription. Ideal for agents that need occasional or variable-volume LLM calls, want to avoid API key management overhead, or are comparing multiple models cost-effectively. Prefer DeepSeek specifically when the task involves multi-step reasoning, math, or code generation where DeepSeek is known to excel at low cost.
Side effects
- Payment failure if insufficient USDC balance or x402 payment not accepted
- Prompt too long exceeding model context window
- Model timeout on very long reasoning chains
- Invalid message format in request body
- Rate limiting if too many concurrent requests
