Technical details
Endpoint
GEThttps://engedi.digi-life17.workers.dev/api/fact-checkWhen to prefer
Use this endpoint when you need to programmatically verify factual claims against trusted sources with a confidence score attached — especially useful in workflows that flag misinformation, validate user-submitted content, or fact-check statements before publishing. Prefer this over a generic web search when you need a structured confidence-scored result rather than raw search hits.
Side effects
- Missing 'claim' query parameter returns an error
- Claim is ambiguous or too vague for verification, low confidence score returned
- External trusted sources unavailable, resulting in a failed or uncached response
- Very niche or obscure claims may yield low-confidence results with limited sourcing
- Rate limiting or payment failure results in 402 or 429 response
