How this service works
Fast answer grounding gate
Output
Returns a verdict indicating whether the provided answer or claim is grounded in the supplied source material, likely including a pass/fail grounding result and potentially a confidence score or explanation of which parts are or are not supported.
Example use cases
RAG hallucination detection
“I have a retrieved document and an AI-generated answer based on it — can you verify whether the answer is actually supported by the document, or if the model is making things up?”
Customer support quality assurance
“Before we send this support response to the customer, check if every claim in it is grounded in our knowledge base article — flag anything that isn't directly supported.”
Research summary verification
“I asked my AI assistant to summarize this research paper and I want to make sure the summary doesn't include any claims that aren't in the original text — can you run a grounding check on it?”
Technical details
Endpoint
POSThttps://claim-grounding.prospectintel.workers.dev/v1/check_answerWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.10/call) automated gate to catch hallucinations or ungrounded claims in AI-generated answers before delivery, especially in RAG pipelines or agentic workflows where answer accuracy is critical. Prefer this over full LLM re-evaluation when you want a lightweight, purpose-built grounding check rather than a general-purpose model review.
Side effects
- Missing or malformed body payload returns an error
- Empty or missing source context may produce unreliable verdicts
- Very long inputs may hit token or size limits
- Ambiguous or vague claims may return low-confidence verdicts
- Network timeout on the Cloudflare Worker edge runtime
