How this service works
Compose, rewrite, translate, and refine content at scale. 25 AI-powered endpoints. Pay-per-call with USDC on Tempo.
Output
Returns a JSON object with a success boolean and a data object containing AI-generated scorecard metrics evaluating the submitted content's quality and relevance to the target keyword. The exact metrics in 'data' may include keyword density, readability, relevance scores, and optimization recommendations.
Example use cases
SEO audit before publishing
“Before I publish this article, can you score it against the keyword 'remote work productivity tips' and tell me how well-optimized it is? Here's the full text of the article.”
Landing page keyword check
“Can you analyze this landing page copy for me and give it a scorecard against the keyword 'affordable project management software'? I want to know if it's targeting that term effectively.”
Content gap analysis for blog
“I wrote a new blog post targeting 'vegan meal prep for beginners' — can you run it through a content scorecard so I can see where I need to improve before handing it off to my editor?”
Technical details
Endpoint
POSThttps://trempest.vercel.app/api/scorecardWhen to prefer
Choose this endpoint when you need to quantitatively evaluate existing content against a specific SEO keyword before publishing. It is ideal for content audits, pre-publish QA pipelines, and keyword optimization workflows. Prefer this over general AI writing endpoints when the goal is measurement and scoring rather than content generation or rewriting.
Side effects
- Missing required 'content' field returns validation error
- Empty content string may produce unreliable or empty scorecard results
- Very long content may hit payload size limits or timeout
- Missing target_keyword results in generic content analysis without keyword-specific scoring
- Service unavailability on Vercel deployment returns 5xx errors
- Payment failure (insufficient USDC) blocks the request at the x402 payment layer
