}Submit one factual claim to ProofMart and get back a verdict (TRUE / FALSE / MIXED / UNVERIFIED), a confidence score (0-100), the evidence behind the verdict, and a signed receipt. Verdicts are remembered in ProofMart's Ledger: a claim that was already checked and is still fresh is answered instantly from memory (the result's 'source' field says 'ledger'; fresh research says 'checker'). Compound claims are split into individual facts automatically. One call = one metered check against the customer's plan.
| Argument | Type | Description |
|---|---|---|
| claim* | string | The factual claim to verify, e.g. 'The Eiffel Tower is in Paris.' |
