## 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 kihustle-keyword-proximity-analyzer-fc55bf52 -d '<json body>'
```

Example prompt: Check how close the words 'automation' and 'income' are to each other in this text: 'Many people are using AI automation to build passive income streams online without quitting their day jobs.'

## When to prefer this

Use this endpoint when you need a lightweight, programmatic way to quantify how closely two specific keywords appear within a block of text — ideal for SEO content auditing, keyword density checks, or verifying that related terms appear near each other in generated content. Prefer this over full NLP pipelines when you only need proximity distance between two known terms without semantic embedding or full document parsing overhead.

## Known failure modes

- Missing required fields (text, word_a, or word_b) result in a validation error
- One or both keywords not found in the provided text may return a null or zero proximity score
- Empty or extremely short text input may yield unreliable results
- Payment failure (x402) if USDC balance is insufficient will block the request
- Malformed JSON body returns a 400-level error
