' ## When to prefer this Use this endpoint when you need to programmatically extract the heading outline or document structure from raw HTML — for example when building table-of-contents generators, SEO auditing tools, content summarizers, or document navigation aids. Prefer this over manual parsing when you want a ready-made structured result without writing your own HTML parser. ## Known failure modes - Malformed or invalid HTML may produce incomplete or empty hierarchy output - Missing 'html' field in request body returns an error - Very large HTML documents may time out or be truncated - HTML with no heading tags returns an empty hierarchy - Non-HTML content passed as the html field may yield unexpected results ## How this service works Kostenlose Guides, Solo-Playbooks und Artikel zu KI, Automation und Side Hustles — für Menschen, die mit echten Systemen online Einkommen aufbauen wollen. Transparent finanziert über faire Affiliate-Links. ## Output Returns a JSON object with a 'result' field indicating 'processed' and a 'status' of 'success', along with the extracted heading hierarchy derived from the submitted HTML. The hierarchy reflects the nested H1–H6 structure present in the document. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "html": { "type": "string" } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "result": "processed", "status": "success" } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/kihustle-heading-hierarchy-extractor-fcb8da46/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from kihustle.tech](https://www.zero.xyz/host/kihustle.tech/llms.txt)
