## 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-486d6f90 -d '<json body>'
```

Example prompt: Pull out only the alphanumeric tokens from this messy log text — strip all the punctuation, symbols, and whitespace and give me just the words and numbers: 'Error[404]: page_not//found!! at 2024-01-15T09:32:11Z — retry=3'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call alphanumeric tokenization step for agent pipelines — ideal when you want to strip punctuation and symbols from text up to 50,000 characters without spinning up a local NLP library. At $0.0065 USDC per call it suits high-volume autonomous agent workflows billed via x402 on Base where serverless micro-payments are already integrated.

## Known failure modes

- Empty or whitespace-only input may return an empty token list
- Text exceeding 50000 characters will be rejected with a validation error
- Non-string input type for 'text' field will cause a schema validation error
- Payment failure via x402 (insufficient USDC balance) will result in a 402 response before processing
- Network timeout on the Cloudflare Workers edge may return a 5xx error

## How this service works

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

## Output

A structured JSON object containing the extracted alphanumeric tokens parsed from the input text, with special characters, punctuation, and whitespace removed or used as delimiters, leaving only sequences composed of letters (a-z, A-Z) and digits (0-9).
