How this service works

Code snippets — Invisible character flags: Invisible character flags 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 invisible character flags result.

Output

Returns a bounded result indicating whether invisible or non-printable Unicode characters were detected within code snippet elements matching the specified attribute and term on the provided page or HTML. Includes flagged character positions or types found within the matched code block.

Example use cases

Security audit of documentation code blocks

“Check the code examples on https://lib.myframework.io/docs/quickstart for any invisible Unicode characters in the code block with attribute 'data-kind' set to 'snippet' — I'm worried someone may have injected hidden characters that could break copy-pasted code.”

Copy-paste integrity check for developer guides

“Scan this HTML for invisible character issues in the code element with id 'sample': <!doctype html><html><body><code id="sample">npm install mypackage --save</code></body></html> — I want to make sure that install command doesn't have any hidden Unicode that would cause it to fail when users copy it.”

Detecting Unicode obfuscation in open-source code snippets

“Analyze the code blocks on https://github.com/someorg/somerepo/blob/main/README.md for any invisible or non-printing Unicode characters in elements related to the term 'example' — I need to verify nothing suspicious was injected in the displayed code.”

Endpoint

When to prefer

Choose this endpoint when you need to specifically detect invisible or hidden Unicode characters embedded within code snippet elements on a static HTML page or supplied HTML fragment. It is ideal for security audits of developer documentation, verifying copy-paste safety of code examples, or detecting Unicode-based obfuscation attacks targeting code blocks. It is not suited for full JavaScript-rendered pages, general text content outside of code elements, or broad Unicode normalization tasks.

Side effects

URL is unreachable or returns a non-200 status — endpoint cannot fetch or parse the page
HTML does not contain a code element matching the specified attribute and attribute value — no result returned
Page requires JavaScript rendering to display code blocks — static parser will miss dynamically injected content
Invisible characters are encoded in a way not covered by the 50-profile engine — may produce false negatives
HTML input exceeds 100,000 character limit — request rejected
term parameter is empty or missing — validation error
