Code Snippets — Duplicate Attribute Values Finder

Choose this endpoint when you need to statically audit HTML — either from a live public URL or a supplied HTML string — for duplicate attribute values specifically within code snippet elements. It is well-suited for documentation QA, pre-publish HTML validation, and accessibility or uniqueness audits on code blocks. Prefer it over generic HTML scrapers when you need a focused, preset-driven analysis of attribute duplication patterns without JavaScript execution overhead.

• URL unreachable or returns non-200 status — parsing cannot proceed
• HTML payload exceeds 100,000 character limit — request rejected
• Attribute name does not match required pattern (must start with letter, alphanumeric/colon/underscore/hyphen) — validation error
• No code snippet elements found in the provided HTML — empty result
• URL requires JavaScript rendering or login — content not accessible via static parse
• Term or attribute_value not found in any code elements — empty duplicate set returned
