# DeepSeek V3.2 Speciale LLM via x402engine

> DeepSeek V3.2 Speciale LLM via x402engine is a paid API for AI agents from x402engine.app, paid per call via x402, $0.003274/call, status unknown (last checked 2026-10-12).

Runs inference on DeepSeek V3.2 Speciale, a large language model, accessible via HTTP 402 micropayment at $0.003274 USDC per call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability deepseek-v3-2-speciale-llm-via-x402engine-385e9b93 -d '<json body>'
```

Example prompt: Ask DeepSeek V3.2 Speciale: 'Explain the differences between TCP and UDP in plain English, then give me a Python code example showing a simple TCP socket server.' Pay per call with USDC on Base.

## When to prefer this

Choose this endpoint when you need pay-per-call access to DeepSeek V3.2 Speciale with no subscription or API key management — ideal for agents that need bursty or unpredictable LLM usage billed in USDC micropayments. Prefer over hosted DeepSeek API when you want x402 HTTP-native payment integration on Base, MegaETH, or Solana. Suitable when you need OpenAI-compatible request/response format with tool-calling and optional streaming.

## Known failure modes

- Payment not settled — 402 response if USDC/USDm balance is insufficient or payment header is missing
- Invalid messages array — 400 if required 'messages' field is absent or malformed
- Unsupported sampling parameter — model may silently ignore or error on unsupported top_k/min_p/logprobs if not in capabilities list
- Context length exceeded — model returns error if messages exceed token limit
- Stream interruption — SSE stream may terminate early on network issues after payment is already settled
- Seed/stop not supported — some parameters documented as model-dependent may be no-ops

## 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

Returns an OpenAI-compatible JSON object containing the model name, an array of choices each with a message (role, content, optional tool_calls), and a finish_reason (e.g. 'stop', 'tool_calls'). When streaming is enabled, returns server-sent events (SSE) in OpenAI format. The top-level 'content' field mirrors the first choice's message content for convenience.
