## How to call it through Zero

Example prompt: Can you extract the 'data-kind' attribute from textarea elements on https://example.com/product-page that contain the word 'product'? I'm expecting the value to be something like 'example'.

## When to prefer this

Choose this endpoint when you need to extract a specific HTML attribute from textarea elements on a static, publicly accessible webpage or from a raw HTML string, and the content does not require JavaScript rendering or login. It is ideal for lightweight, per-attribute queries on known form pages, QA checks, or data enrichment pipelines that need a single bounded attribute result at low cost ($0.01 USDC). Prefer alternatives if you need full DOM traversal, JavaScript-rendered pages, or bulk multi-attribute extraction across many elements.

## Known failure modes

- URL is not publicly accessible or requires authentication — extraction fails
- No textarea elements matching the search term are found — empty or null result
- Requested attribute does not exist on matched textarea elements — empty result
- HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match required pattern (must start with a letter, alphanumeric/colon/underscore/hyphen, max 50 chars) — validation error
- Page requires JavaScript rendering to display textarea — static parser cannot access element
- URL is malformed or exceeds 2048 character limit — request rejected
