What Proof Kit does: checks whether US case citations exist in CourtListener and whether case names match, and signs the result. It does not provide legal advice and does not judge whether a case supports an argument.
No warranty of completeness: coverage depends on public databases. Always open the source link before relying on a result.
Free tier: 100 citations per month per network; we may change limits to prevent abuse.
Paid plans: invoiced monthly in USD during early access; cancel any time before the next invoice. Pilot guarantee: if we find no errors in the AI output you provide during the 30-day pilot, the pilot fee is refunded in full.
Acceptable use: no automated scraping beyond the API limits; no attempts to forge receipts.
