# ONE Engine Text Token Word Counter

> ONE Engine Text Token Word Counter is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Counts the number of words (token tier T1) in a given text string up to 50,000 characters.

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-token-word-counter-18934391 -d '<json body>'
```

Example prompt: Count the words in this text for me: '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 cheap, lightweight word count or text token measurement for a string up to 50,000 characters, especially in an autonomous agent pipeline that already uses x402 micropayments on Base. At $0.0005 USDC per call it is cost-effective for high-frequency counting tasks where you don't want to run local NLP libraries.

## Known failure modes

- Text exceeding 50,000 characters may be rejected or truncated
- Empty text field may return zero or an error
- Payment failure via x402 will block the request
- Malformed JSON body will result in a 400-level error
- Non-string text values may cause validation errors

## 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 word count and potentially related token statistics for the submitted text. The response includes computed metrics derived from parsing the input string.
