## 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 apexapi-word-count-505c02f8 -d '<json body>'
```

Example prompt: Can you count how many words are in this paragraph for me: 'The quick brown fox jumps over the lazy dog and then ran away into the forest'?

## When to prefer this

Use this endpoint when you need a quick, paid-per-call word count computation without managing API keys. Suitable for agents that need to verify document length, enforce word limits, or compute text metrics programmatically within a USDC-based micropayment workflow on Base.

## Known failure modes

- Empty input string returns zero or error response
- Extremely long text inputs may be truncated or rejected
- Non-text or binary input may cause a parsing error
- Payment failure (402) if USDC balance is insufficient
- Network timeout for very large text payloads

## How this service works
