How this service works
Vianerds Objects: fünf ruhige Alltagsobjekte in einer klaren, funktionalen Kollektion.
Output
Returns a JSON object with a numeric score (0–100), the audited page URL as target, a verdict string (e.g. 'repair_priority_signals'), a schemaVersion identifier, and an array of priorityActions each containing a fix description, a machine-readable code, and a severity level (e.g. 'medium').
Example use cases
Pre-launch SEO health check
“Before I publish my new landing page, can you audit this HTML and tell me its SEO score and what I should fix first? Here's the full page markup: <!DOCTYPE html><html><head><title>My Product</title></head><body>...</body></html> — the URL will be https://mysite.com/launch”
E-commerce product page diagnosis
“My product listings aren't ranking well — can you run an audit on this product page HTML from https://shop.example.com/widget-pro and tell me what priority signals are missing or need repair?”
Content team SEO review workflow
“I need to check every blog post draft for on-page SEO issues before we publish. Can you analyze this HTML for https://blog.example.com/post-42 and give me the score, verdict, and a list of what to fix with their severity?”
Technical details
Endpoint
POSThttps://vianerds.com/x402/v1/page-signal-auditWhen to prefer
Choose this endpoint when you have static HTML available client-side and need a structured, scored audit with actionable fix codes — without requiring the service to fetch the page itself. Ideal for pre-publish validation, CI/CD SEO gates, or content pipelines where you already hold the HTML. Prefer alternatives if you need live crawling, JavaScript-rendered page analysis, or backlink/off-page signals.
Side effects
- HTML below 20 characters minimum returns validation error
- HTML exceeds 250,000 character limit causing rejection
- URL does not match required HTTPS pattern causing schema validation failure
- Malformed or non-HTML content may produce inaccurate or empty priorityActions
- Payment failure at $5 USDC per call results in 402 response before audit runs
