## How to call it through Zero

```sh
zero fetch --capability word-frequency-analyzer-39c31224
```

Example prompt: Can you analyze the word frequency for https://example.com/blog/seo-tips and show me the top words, bigrams, and how often each appears?

## When to prefer this

Choose this endpoint when you need detailed word-level frequency statistics including bigrams, per-word share percentages, and both total and unique word counts for a page. It goes deeper than a simple keyword list by providing full frequency distribution across the top 50 terms. Prefer it over sibling endpoints like keyword-extract (which returns only top 20 terms without share percentages) when you need richer frequency data for SEO analysis or content auditing.

## Known failure modes

- Page URL is unreachable or returns a non-200 status — endpoint may return an error or empty results
- Page has very little text content — fewer than 50 unique words returned
- JavaScript-heavy pages that require rendering may not yield full text content
- Payment failure via x402 protocol results in 402 response and no data returned
- Invalid or missing URL parameter causes a 400-level error

## How this service works

Word frequency for a page: the top 50 words (stopwords removed) with counts and share, total and unique word counts, and top bigrams. Topic analysis and SEO term research. $0.01 per page.

## Output

Returns the top 50 words (with stopwords removed) along with their individual counts and frequency share as a percentage of total content, the total word count, unique word count, and a list of top bigrams — useful for understanding page topic coverage and keyword density.
