How this service works
Check a generated answer against a set of approved facts and forbidden claims to catch ungrounded or off-limits statements. Flags forbidden claims found in the answer and warns when the answer matches none of the approved facts.
Output
Returns a JSON object with a boolean 'valid' field indicating whether the answer passed, an 'issues' array listing any detected problems (e.g. forbidden claims found), a 'matched_facts' array showing which approved facts were confirmed, and the endpoint name.
Example use cases
Example prompt
“Before I send this answer to the user — 'Our Pro plan costs $20/month and includes unlimited seats' — can you trust-check it against these approved facts: ['The plan costs 20 dollars per month', 'Seats are limited to 10 users'] and flag it if it contains any of these forbidden claims: ['unlimited seats', 'free trial included']?”
Technical details
Endpoint
POSThttps://gateway.apiosk.com/trust-checks/knowledgeWhen to prefer
Use this endpoint when you need to validate AI-generated or agent-produced answers against a curated set of ground-truth facts and a blocklist of prohibited claims before delivering the response to end users — especially in customer support, compliance, or product documentation contexts where factual accuracy and policy adherence are critical.
Side effects
- Missing 'answer' field returns validation error
- Empty approved_facts array may result in no matched_facts
- Forbidden claims list not provided may skip claim checking
- Network timeout on large answer texts
- Ambiguous or overlapping facts and forbidden claims may produce inconsistent results
