# Stuff on Screen Content Effort Checker

> Free, independent checks of public English-language articles. Returns a 0–100 heuristic estimate, seven category scores, supporting excerpts, improvement suggestions and a saved report link. No API key required.

## Use the tool
- [Web checker](https://tools.stuffonscreen.com/contentEffort): paste a public page URL.
- [API documentation](https://tools.stuffonscreen.com/contentEffort/api): request examples, response fields, limits and responsible interpretation.
- [OpenAPI specification](https://tools.stuffonscreen.com/openapi.json): machine-readable API contract.

POST https://tools.stuffonscreen.com/api/analyze with Content-Type: application/json and {"url":"https://example.com/article"}. Replace the example URL with a real public article. Optional "fresh":true bypasses the six-hour analysis cache.

The result ID forms a report URL at https://tools.stuffonscreen.com/contentEffort/{id}. Retrieve the same stored JSON with GET https://tools.stuffonscreen.com/api/results/{id}. Reading an existing result does not re-analyze the page. New checks preserve old reports.

## Interpretation
These are Stuff on Screen's rules, not Google's private contentEffort score. Not a fact check, AI-writing test, plagiarism detector or ranking predictor. Compare scores only within the same rubricVersion; check confidenceReason for extraction and page-purpose limitations. English text and HTML metadata only; no visual asset verification or search-result comparison. Qualitative work may be underrated and fabricated claims may receive points. Review the quoted evidence and limitations, not just the number. Do not invent first-hand experience, data or sources to improve a score.

## Access
Submit one analysis at a time. Handle HTTP 429 using Retry-After. Approximate per-connection edge rate: 20 analysis requests per minute. Shared allowance: 1,000 uncached/fresh fetch attempts per UTC day, including failures; resets at midnight UTC. Cached checks and saved-result reads do not consume that daily allowance. No paid AI scoring API is used. Only public URLs; no credentials, local/private networks, login bypass, page JavaScript or unpublished draft submission. Successful reports store the submitted page URL and short excerpts and are visible to anyone with the link. Individual reports are noindex; the tool and API documentation are indexable.
