## When to prefer this

Choose this endpoint when you need a structured, quantitative scorecard of content quality relative to a specific SEO keyword — particularly useful before publishing articles, landing pages, or product descriptions. Prefer this over general AI writing feedback when you need consistent, comparable numeric scores across multiple pieces of content or when automating content QA pipelines.

## Known failure modes

- Missing required 'content' field returns validation error
- Empty string content may produce low-confidence or error response
- Very long content payloads may time out or be truncated
- Missing target_keyword returns a general quality score without keyword-specific analysis
- Invalid or malformed JSON body returns 400 error
- Service unavailability returns 5xx error
