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 time-labels-adjacent-word-pair-frequency-a6251226 -d '<json body>'
```

Example prompt: Analyze the adjacent word-pair frequency in the <time> elements on https://example.com/blog — look for the term 'product' in elements where the id attribute equals 'sample', and compare against these previous texts: ['Older example'].

## When to prefer this

Choose this endpoint when you specifically need bigram (adjacent word-pair) frequency analysis scoped to HTML <time> elements, with optional attribute filtering. It is ideal for NLP preprocessing of temporal labels, blog timestamps, or event date text. Prefer it over general-purpose bigram tools when the target data lives inside <time> tags and you want bounded, cheap single-call results without JavaScript rendering.

## Known failure modes

- URL is inaccessible or returns non-200 status — no content to parse
- HTML content exceeds 100,000 character limit — request rejected
- No <time> elements found matching the specified attribute/value — empty result
- Term not found in any time element text — zero-frequency result
- Invalid attribute name pattern — schema validation error

## How this service works

Time labels — Adjacent word-pair frequency: Adjacent word-pair frequency for Time labels. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded adjacent word-pair frequency result.

## Output

Returns bounded adjacent word-pair (bigram) frequency counts extracted from <time> HTML elements on the target page or supplied HTML, scoped to the specified attribute and term filter.
