## 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 one-engine-text-token-word-counter-0cb6d985 -d '<json body>'
```

Example prompt: How many words are in this text? 'The quick brown fox jumps over the lazy dog. It was a bright cold day in April, and the clocks were striking thirteen.'

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.0015 USDC), pay-per-call word count for text up to 50,000 characters and are already operating in an x402/Base payment environment. Prefer it over rolling your own counter when you need a reliable, API-native solution that integrates with autonomous agent payment flows on Base.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text field returns zero or error
- Payment failure via x402 on Base blocks the call
- Malformed JSON body causes 400 error
- Cloudflare Worker timeout for very large inputs near the character limit

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
