Check a claim against DFX's evidence

verify
Read-onlyIdempotent

SUPPORTED, PARTIALLY_SUPPORTED, CONTRADICTED or UNKNOWN for a claim, with the observations. Give a sentence ('Family Office X invested in Company Y in 2025', 'Z is a business development company', 'A is the investment adviser of BDC B', 'Pension P committed to Fund F') or a structured subject / predicate / object / year. SUPPORTED always carries at least one evidence row with a citation; a name resolves only to a record carrying that name, otherwise the answer is UNKNOWN with candidates. DFX contradicts only what its own record contradicts; absence of evidence is UNKNOWN, never CONTRADICTED. Its predicates cover investment, acquisition, adviser, commitment and identity claims (business development company, registered investment adviser, family office, venture capital, private equity); property facts are outside them. ACCESS: without a paid DFX plan on the vertical, a list returns its first 5 rows in full and a count of the rest by type (locked.count, locked.by_type), never the rows; a record names its subject and the first 3 related names per section; contact values (email, phone, profile URLs) and decision-maker names are never returned, only their types and counts. Every answer says what it withheld in entitlement and locked. Full access: DFX Intelligence, 7 days free at https://dfxintel.com/data-factory/plans.
