How this service works
125 production APIs behind HTTP 402 micropayments. 87 LLMs, Kling V3 and Hailuo video generation, image generation, code execution, travel search, web scraping, TTS, and transaction simulation. Pay with USDC on Base, USDm on MegaETH, or USDC on Solana.
Output
An OpenAI-compatible JSON response containing the assistant's message (with optional reasoning field), finish reason, model name, and any tool_calls the model requested. If streaming is enabled, returns Server-Sent Events in OpenAI SSE format instead.
Example use cases
Agentic tool-use reasoning pipeline
“I need DeepSeek R1 to decide which of these three functions to call based on the user's request — give it this system prompt, the user message about booking a flight, and these two function definitions, then tell me what tool call it returns.”
Complex code debugging with chain-of-thought
“Have DeepSeek R1 reason through why this Python function is returning incorrect Fibonacci numbers for large inputs and suggest a fix — I want to see its full reasoning, not just the answer.”
Pay-per-call LLM for low-volume agent tasks
“Use DeepSeek R1 to evaluate whether this legal clause contains any ambiguity that could expose us to liability — just pay the micropayment per call, I don't want to manage an API subscription.”
Technical details
Endpoint
POSThttps://x402engine.app/api/llm/deepseek-r1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DeepSeek R1's strong chain-of-thought reasoning capabilities on a pay-per-call basis without committing to a subscription or managing API credentials. Ideal for agents that call LLMs infrequently or need cost-controlled per-request billing in USDC. Prefer this over managed providers when you want a no-subscription, crypto-native micropayment flow with OpenAI-compatible request/response format and optional streaming.
Side effects
- Payment not settled — HTTP 402 returned if USDC micropayment fails or wallet lacks funds
- Invalid messages array — missing required 'role' or 'content'/'tool_calls' fields returns a validation error
- Unsupported parameter — passing a parameter not supported by DeepSeek R1 (check /docs/llm-capabilities.md)
- Context length exceeded — very long conversations may exceed model context window
- Streaming timeout — long reasoning chains may hit connection timeout before completion
