Technical details
Endpoint
POSThttps://verity-bzw7.onrender.com/verify/quickWhen to prefer
Use Verity when an AI agent needs to fact-check or validate a specific factual claim before acting on it, publishing content, or presenting information to a user. Especially suited for agentic pipelines where trust verification is a gating step. Prefer over general web search when you need a structured, machine-readable verdict with confidence and evidence rather than raw search results.
Side effects
- Missing required 'claim' field returns validation error
- Ambiguous or unanswerable claims may return 'uncertain' with low confidence
- Highly obscure or niche claims may lack evidence and return uncertain verdict
- Rate limiting or service unavailability from hosted render.com instance
- Payment failure (x402) results in 402 response before processing
