# CSS Math Auto Single Text Node Remapping Detector

> CSS Math Auto Single Text Node Remapping Detector is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).

Detects which declared single text nodes in a webpage's DOM would require mathematical italic Unicode codepoint remapping and identifies where comment/inline boundaries trigger multiple conversions within a single identifier, before a formula or font exporter processes them.

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 css-math-auto-single-text-node-remapping-detector-a355636a -d '<json body>'
```

Example prompt: Can you check https://example.com/mathpage and tell me which single text nodes would need mathematical italic Unicode remapping, and where any DOM comment or inline boundaries are splitting identifiers and causing multiple conversions?

## When to prefer this

Use this endpoint when you need to audit a specific webpage for CSS math-auto Unicode remapping issues prior to running a formula or font exporter, particularly when you suspect DOM comment nodes or inline boundaries are causing unintended multi-conversion splits in mathematical identifiers. It is best suited for pre-export validation workflows rather than general accessibility or SEO checks.

## Known failure modes

- Invalid or inaccessible URL returns an error response
- Page with no CSS math declarations yields empty results
- Dynamically rendered math content may not be detectable from static HTML fetch
- Extremely large DOMs may cause timeout or incomplete analysis
- Non-HTML content types (PDF, images) cannot be analyzed

## How this service works

Ermittelt, welche deklarierten Einzeltextknoten mathematische Italic-Codepunkte anfordern würden und wo DOM-Kommentar-/Inlinegrenzen mehrere Konversionen in einem Bezeichner auslösen, bevor ein Formel- oder Schrift-Exporter umstellt.

## Output

A structured report listing the specific single text nodes that would require mathematical italic Unicode codepoint remapping, along with the locations of DOM comment and inline boundaries that cause multiple consecutive conversions within a single mathematical identifier, enabling preemptive fixes before formula or font export.
