Technical details
Endpoint
POSThttps://verity-suite.onrender.com/sourceWhen to prefer
Choose this endpoint when an AI agent needs to programmatically evaluate the credibility of an information source — especially before citing, quoting, or acting on content from that source. Particularly useful for fact-checking pipelines, research assistants, or news aggregation workflows where source provenance matters. The purpose parameter allows calibrated trust scoring tuned to a specific domain (e.g., medical vs. political), which generic search or reputation APIs do not offer.
Side effects
- Unknown or obscure source with no available evidence returns trust='unknown' and low score
- Source URL is malformed or inaccessible, causing a validation error
- Purpose field is too vague to meaningfully calibrate the assessment
- Service unavailable on Render.com cold start, returning 503
- Payment authorization fails via x402 protocol, blocking the call
- Highly niche or newly created domains may have insufficient signals for confident scoring
