How this service works
Multi-source fact verification API
Output
Returns a JSON object with success boolean, plus two claim objects (claim_a, claim_b) each containing their individual fact-check results, and a comparison object summarizing how the two claims relate — which is better supported, whether they contradict, and overall verdict based on multi-source verification.
Example use cases
Example prompt
“Can you compare these two claims and tell me which is more accurate: claim A is 'The Eiffel Tower is 300 meters tall' and claim B is 'The Eiffel Tower is 330 meters tall'? Run both through Veritas so I can see which one holds up.”
Technical details
Endpoint
POSThttps://veritas.orbonomy.xyz/api/compareWhen to prefer
Choose this endpoint when you need to compare two specific textual claims head-to-head for factual accuracy using multi-source verification. It is especially useful for dispute resolution, journalism fact-checking, misinformation detection, or comparing competing narratives. Prefer this over single-claim verifiers when the task is explicitly comparative — i.e., the user wants to know not just whether one claim is true, but how two claims stack up against each other.
Side effects
- Missing claim_a or claim_b returns 400 validation error
- Unsupported language code may cause degraded or empty results
- Very long or ambiguous claims may return low-confidence comparison
- Payment failure (x402) prevents call from completing
- Service timeout if external sources are slow to respond
- Nonsensical or non-falsifiable claims may return inconclusive comparison
