# whatchuneed LLM Batch Processing

> whatchuneed LLM Batch Processing 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).

Submits a batch of items to be processed by a large language model in a single pay-per-call API request, returning structured results for each item.

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-batch-processing-bb9d4729 -d '<json body>'
```

Example prompt: Process this list of 10 customer reviews using the task 'classify sentiment as positive, negative, or neutral' and give me back the results for each one in a single batch call.

## When to prefer this

Choose this endpoint when you need to apply a single LLM task instruction uniformly across multiple inputs in one API call, avoiding the overhead of many individual requests. It is especially useful for bulk classification, extraction, or summarization workflows where cost efficiency (single $0.1 USDC payment per batch) and consolidated error reporting matter.

## Known failure modes

- Missing required 'items' array returns a validation error
- Empty items array may return zero results with no errors
- Individual items within the batch may fail independently, reflected in error_count
- Malformed item objects may cause partial batch failures
- Payment failure via x402 protocol blocks the entire request
- Rate limiting or quota exhaustion may reject the request entirely
