Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-alphanumeric-token-extractor-ad50eb3c -d '<json body>'
```

Example prompt: Extract all alphanumeric tokens from this raw text: 'Hello, world! 123 foo_bar @baz #test — just give me the clean word and number tokens.'

## When to prefer this

Choose this endpoint when you need a lightweight, cheap, pay-per-call alphanumeric tokenizer for preprocessing text in agent pipelines. At $0.0005 USDC per call via x402 on Base, it is cost-effective for high-volume tokenization tasks where you want to strip punctuation and special characters and retain only alphanumeric tokens from arbitrary text up to 50,000 characters.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty text input — may return empty token list or error
- Payment not fulfilled via x402 — 402 Payment Required response
- Malformed JSON body — 400 Bad Request
- Network timeout on Cloudflare Workers edge

## How this service works

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

## Output

Returns a JSON object containing the extracted alphanumeric tokens parsed from the input text, likely as an array of token strings or a structured token map derived from the submitted text.
