Landing page keyword check
“Here's the copy for my new SaaS landing page — can you analyze it against the target keyword 'project management software for startups' and give me an SEO scorecard?”
Product description optimization
“I need to know how well this product description targets 'wireless noise-cancelling headphones under $100' — can you run it through the SEO scorecard and show me the results?”
Technical details
Endpoint
POSThttps://tempestars.vercel.app/api/scorecard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, AI-powered SEO scorecard for a specific piece of content against a target keyword, especially in automated content pipelines where you want per-call pay-as-you-go pricing via USDC rather than a subscription SEO tool. Best suited for single-document analysis rather than bulk site audits.
Side effects
- Missing required 'content' field returns validation error
- Empty string content may return low scores or an error
- Overly long content may exceed token or size limits
- Invalid or missing target_keyword defaults to generic content analysis without keyword scoring
- Network timeout on very large content payloads
- Payment failure via x402 protocol prevents request from being processed
