## When to prefer this

Use this endpoint when you need a structured, AI-powered quality and SEO scorecard for a specific piece of content relative to a target keyword. Prefer this over generic content analysis when you want quantified scoring and keyword-alignment metrics in a single pay-per-call call without a subscription.

## Known failure modes

- Missing required 'content' field returns validation error
- Empty or very short content may produce low-confidence scores
- Invalid or missing target_keyword may result in generic scoring without keyword-specific analysis
- Payment failure (non-payment of 0.2 USDC via x402) blocks the request
- Overly long content may exceed token limits causing truncation or error
