# wafermap.xyz DeepSeek V4 Pro

> wafermap.xyz DeepSeek V4 Pro is a paid API for AI agents from wafermap.xyz, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-31).

Runs DeepSeek's top-tier reasoning model for hard math, code, and logic problems, returning a text completion for a given prompt.

## Facts

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 wafermap-xyz-deepseek-v4-pro-cdd959f9 -d '<json body>'
```

Example prompt: Use DeepSeek V4 Pro to solve this competitive programming problem for me: given an array of integers, find the maximum sum subarray using divide and conquer — write the full implementation in Python with time complexity analysis, and keep the answer under 1024 tokens.

## When to prefer this

Choose this endpoint when the task demands deep, multi-step reasoning, rigorous mathematical work, or complex code generation that benefits from a frontier-class model. Prefer it over DeepSeek V4.1 Flash or Llama 4 Scout when accuracy and reasoning depth matter more than speed or cost. Use it for hard competitive programming, proofs, algorithm analysis, or any problem where a weaker model would make reasoning errors.

## Known failure modes

- Prompt too long (exceeds 24000 characters) — request rejected
- max_tokens out of range (must be between 1 and 2048) — validation error
- Payment failure via x402 protocol — 402 response if USDC not authorized
- Model timeout on extremely complex reasoning chains
- Truncated output if max_tokens is too low for the complexity of the answer

## How this service works

DeepSeek V4 Pro — DeepSeek's top model for hard reasoning, math and code.

## Output

A text completion from DeepSeek V4 Pro containing the model's answer, reasoning, code, or analysis — up to 2048 tokens. The response reflects the model's strongest capabilities in multi-step reasoning, mathematical derivation, and code generation.
