## 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-alphanumeric-token-extractor-e6a1f086 -d '<json body>'
```

Example prompt: Pull out only the alphanumeric tokens from this text for me — strip out all punctuation, symbols, and whitespace tokens: 'Hello, world! This is test #42 — with some $pecial ch@racters.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call alphanumeric tokenization utility without spinning up your own text processing pipeline. Ideal for agents that occasionally need to clean or tokenize text at low volume and want micro-payment billing via x402 on Base rather than a subscription.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty text input — may return empty token list or error
- Payment failure via x402 — 402 response returned before processing
- Malformed JSON body — 400 error returned
- Network timeout on Cloudflare Worker edge node

## How this service works

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