# Code Snippets — Adjacent Word-Pair Frequency

> Code Snippets — Adjacent Word-Pair Frequency is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Analyzes a web page or HTML containing code snippets and returns the frequency of adjacent word pairs (bigrams) within the code content.

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 code-snippets-adjacent-word-pair-frequency-3892ac0d -d '<json body>'
```

Example prompt: Fetch the page at https://docs.example.com/getting-started and count how often adjacent word pairs appear in the code snippets — I'm looking for the term 'function call' and want bigram frequencies from the element with id 'sample'.

## When to prefer this

Choose this endpoint when you need bigram (adjacent word-pair) frequency statistics specifically from code snippet HTML elements on a public web page or supplied HTML, and you want a fast, low-cost ($0.01 USDC) single-call result without needing full NLP pipeline infrastructure. Prefer this over general text analysis tools when the target content is code blocks rather than prose.

## 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 code snippet elements found matching the specified attribute/attribute value — empty or null result
- Term parameter missing or too short — validation error
- JavaScript-rendered content not available — static parser only, dynamic content missed
- Rate limit or capacity exceeded on the shared 50-profile engine — request queued or failed

## How this service works

Code snippets — Adjacent word-pair frequency: Adjacent word-pair frequency for Code snippets. 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 a bounded result containing adjacent word-pair (bigram) frequency counts extracted from code snippet elements on the specified page or HTML input, scoped to the relevant element identified by the given attribute and attribute value.
