How this service works
DeepSeek's reasoning model — chain-of-thought reasoning competitive with o3 at fraction of cost
Output
Returns the model's chain-of-thought reasoning trace and final answer text, showing the step-by-step reasoning process DeepSeek R1 used to arrive at its conclusion, comparable in quality to OpenAI o3 but at significantly lower cost.
Example use cases
Example prompt
“Use DeepSeek R1's chain-of-thought reasoning to figure out the optimal strategy for this game theory problem: three players each choose a number between 1 and 100, and the player closest to half the average wins — walk me through the reasoning step by step.”
Technical details
Endpoint
POSThttps://x402-gateway-production.up.railway.app/api/llm/deepseek-r1When to prefer
Choose this endpoint when you need strong multi-step logical reasoning, math problem solving, or chain-of-thought analysis and want o3-competitive quality at a fraction of the cost. Prefer over GPT-4o or Claude endpoints when cost efficiency matters and the task benefits from explicit reasoning traces. Ideal for agentic workflows that need to solve complex problems step by step without paying premium model prices.
Side effects
- Payment failure — insufficient USDC balance or x402 payment rejected, returns 402 Payment Required
- Invalid prompt format — malformed request body returns 400 Bad Request
- Model timeout — complex reasoning chains exceeding time limits return 504
- Rate limiting — too many concurrent requests returns 429 Too Many Requests
- Upstream DeepSeek API unavailability returns 503 Service Unavailable
