How this service works
Bundled execution of the Content grade workflow - Grade a page's content quality - extract the readable content then analyze keyword density. One x402 payment runs 3 underlying tools (extract, keywords, readability-score); partial-success per step.
Output
Returns a composite content grade combining: (1) extracted readable text from the page, (2) keyword density analysis, and (3) a readability score — with partial-success reporting per step if any sub-tool fails.
Example use cases
Example prompt
“Can you grade the content quality of https://example.com/my-blog-post — I want to know the keyword density and readability score?”
Technical details
Endpoint
POSThttps://agent402.tools/api/skill/content-gradeWhen to prefer
Use this endpoint when you need a bundled, single-payment content audit covering extraction, keyword density, and readability in one shot — rather than calling three separate tools individually. Ideal for SEO audits, content quality checks before publishing, or comparing page quality across multiple URLs efficiently.
Side effects
- URL is unreachable or returns non-200 — extraction step fails, downstream steps may be skipped
- Page has no extractable text (e.g. pure JavaScript SPA with no SSR) — content extraction returns empty
- Payment not completed — entire workflow blocked with 402 response
- Partial failure: extraction succeeds but keyword or readability step errors — result includes per-step status
- Invalid or malformed URL input — request rejected with validation error
