How this service works
Textarea defaults — Adjacent word-pair frequency: Adjacent word-pair frequency for Textarea defaults. 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 data extracted from the matching textarea element on the target page or HTML, showing how often each word pair adjacent to the specified term appears in the textarea's content, with optional comparison against previously supplied text snapshots.
Example use cases
Monitoring form default text changes
“Check the textarea with id 'description' on https://myapp.com/signup for adjacent word pairs containing 'account', and compare how the bigram frequencies have shifted from last month's snapshot: ['Create your account today to get started'].”
Competitive content analysis
“Pull the adjacent word-pair frequencies for the word 'free' from the textarea with attribute 'data-kind' set to 'promo' on https://competitor.com/pricing — I want to see what word combinations they use around that term.”
QA for textarea default copy
“Parse the HTML I'm giving you and find all adjacent word pairs containing 'example' in the textarea with id 'guide' — I want to make sure the default copy reads naturally before we ship: <!doctype html><html><body><textarea id="guide">This is an example guide for new example users</textarea></body></html>”

Choose this endpoint when you need lightweight, static extraction of bigram frequencies specifically from HTML textarea elements — particularly when you want to track or compare word-pair patterns in form default content over time. It is ideal for content audits, QA workflows, and competitive analysis where JavaScript rendering is not required and you can target a specific textarea by attribute.
Side effects

- HTML payload exceeds 100,000 character limit — request rejected
- Term not found in any textarea content — zero-frequency result returned
- JavaScript-rendered content not available — only static HTML is parsed
