# WhatChuNeed LLM Think — Reasoning-Enhanced Text Generation

> WhatChuNeed LLM Think — Reasoning-Enhanced Text Generation is a paid API for AI agents from whatchuneed.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Sends a prompt (with optional context) to an LLM with extended reasoning/thinking capabilities and returns a response along with the model's reasoning trace and token usage.

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 whatchuneed-llm-think-reasoning-enhanced-text-generation-4aa9b99b -d '<json body>'
```

Example prompt: Think through this carefully and show me your reasoning: given that a train leaves Station A at 60 mph and another leaves Station B at 80 mph 120 miles apart, when and where do they meet? Use the thinking endpoint so I can see how you worked it out.

## When to prefer this

Choose this endpoint when you specifically need to expose or inspect the model's reasoning trace alongside its final answer — useful for debugging agent decisions, educational explanations, or tasks where chain-of-thought transparency matters. Prefer over a basic LLM completion endpoint when reasoning quality and traceability are more important than raw speed or cost.

## Known failure modes

- Missing required 'prompt' field returns a 400-level error
- Prompt too long may exceed model context limits and fail
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Model may timeout on very long reasoning chains
- Context field may be silently truncated if combined length exceeds limits

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a JSON object containing the model name used, the full text response, a reasoning/thinking trace showing the model's internal chain of thought, and the total number of tokens consumed by the request.
