How this service works
Evaluate a source for credibility, transparency, evidence quality, bias signals, and limitations
Output
Returns a structured credibility assessment of the provided URL including ratings across credibility, transparency, evidence quality, detected bias signals, and notable limitations of the source.
Example use cases
Journalism source vetting
“Before I cite this article in my piece, can you score the credibility and bias of https://globaleconomics-report.com — I'm writing about trade policy and need to know if the evidence quality holds up?”
Academic research source check
“I'm reviewing sources for a paper on vaccine safety — can you assess https://healthpolicyjournal.org for credibility, transparency, and whether its evidence meets research standards?”
Misinformation triage for social posts
“Someone shared https://naturalnewsalert.net in our community group — can you quickly evaluate how trustworthy and unbiased this site is so I know whether to flag it?”
Technical details
Endpoint
POSThttps://red-breeze-8b8c.keenanbooker83.workers.dev/score-sourceWhen to prefer
Use this endpoint when you need a structured, multi-dimensional credibility assessment of a specific public URL — especially when bias detection, evidence quality, and transparency are all needed together. Prefer this over generic web-scraping or summarization tools when the goal is explicitly to judge source trustworthiness rather than extract content.
Side effects
- URL is paywalled or inaccessible — scoring may be incomplete or fail
- URL points to a non-public or broken page — returns error or low-confidence result
- Source is too short or lacks sufficient content for meaningful analysis
- Highly obscure or newly created domains may yield low-confidence scores
- Malformed or invalid URL format causes request rejection
