Trademark precheck (agent-tier preview of /api/legal/trademark-check $0.50): live USPTO TSDR verification of serial/registration numbers you already have — returns the official LIVE/DEAD status, owner, classes, and dates verbatim. Does not run candidate-discovery research or produce a conflict-risk verdict; those require the full product. For legal, brand-naming, and IP agents with small per-call budgets.
