lobre.lat Fact-Linkage Claim Verifier

Use this endpoint when you need to verify specific factual claims, especially those that may appear in news, social media, or user-generated content. Prefer this over a generic LLM query because it queries structured fact-check databases first, providing cited sources and improving accuracy; the LLM is only a fallback. Best for discrete, verifiable assertions rather than open-ended questions.

• Claim is too vague or ambiguous to verify — returns uncertain or null result
• Unsupported language code — falls back to English or returns error
• Claim is outside fact-check database coverage and LLM fallback is also inconclusive
• Payment of $0.12 USDC not received — request rejected with 402 status
• Network timeout or upstream database unavailability
