# ONE Engine Text Token Word Frequency – Top 10

> ONE Engine Text Token Word Frequency – Top 10 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-02).

Extracts the top 10 most frequent words (token word count) from a given text, 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-frequency-top-10-a6aba8ae -d '<json body>'
```

Example prompt: Can you find the top 10 most frequently used words in the following article text? Here it is: [paste text up to 50,000 characters]

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.03 USDC) word frequency ranking for a text document and only need the top 10 results. Ideal for lightweight NLP tasks in autonomous agent pipelines where full NLP libraries are unavailable or cost-prohibitive. Prefer this over a general-purpose LLM call when you want a deterministic, structured frequency count rather than a narrative summary.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text input — may return empty result or error
- Non-English or mixed-language text may produce unexpected tokenization results
- Payment failure via x402 on Base — call not processed
- Malformed JSON body — 400 error

## How this service works

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