Example use cases
SEO audit before publishing
“Before I publish this product page, run a Tempest scorecard on it and tell me how well it targets the keyword 'noise-cancelling headphones for work' — here's the full page copy.”
Content quality check for agency client
“I need to evaluate this 800-word article my freelancer submitted. Score it against the keyword 'small business accounting software' and give me the scorecard so I can decide if it's ready to publish.”
Comparing content optimization score
“Can you score this revised landing page copy against the keyword 'vegan meal prep delivery' using the Tempest scorecard? I want to see if the rewrite improved the quality metrics compared to what I had before.”

Endpoint
POSThttps://tempest-2zzx.vercel.app/api/scorecardWhen to prefer
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.
Side effects
- 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
