# ONE Engine Text Alphanumeric Token Extractor

> ONE Engine Text Alphanumeric Token Extractor is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0007/call, status unknown (last checked 2026-10-02).

Extracts alphanumeric tokens from a given text string, returning only alphanumeric segments.

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-3e80dd73 -d '<json body>'
```

Example prompt: Extract all the alphanumeric tokens from this text: 'Hello, world! Order #12345 arrived on 2024-06-01 — thank you!' and give me just the alphanumeric segments.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call alphanumeric tokenizer with no subscription overhead, especially in agentic pipelines running on Base/x402. Ideal for preprocessing text before indexing, keyword extraction, or passing cleaned tokens to downstream models. Prefer this over regex-based self-implementation when you want a hosted, consistent tokenization result without managing infrastructure.

## Known failure modes

- Text exceeding 50,000 characters may be rejected or truncated
- Empty text input may return an empty token list or error
- Payment failure via x402 will block the request from processing
- Malformed JSON request body returns an error
- If the text contains no alphanumeric characters, the result will be an empty token set

## 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 alphanumeric tokens extracted from the input text, with non-alphanumeric characters (punctuation, whitespace, symbols) removed or used as delimiters. The exact structure may vary but typically includes a list or array of token strings derived from the input.
