Use when an agent must break a tie or split a test and cannot be seen to have chosen: one or more fair coins, each result and the tally of heads and tails, cryptographically random rather than Math.random. Do not use to pick among more than two options (/v1/random/pick) or to order a list (/v1/random/shuffle). No API key, no account.

US consumer-demand signal (retail sales)

Find North Carolina (NC) court cases and hearing dates for a PERSON by name. Both first and last are required. For a company, LLC, insurer or landlord use search-cases-by-business instead — person search cannot match an organisation and returns nothing rather than a worse answer. SLOW: a live portal query, 15-50s; allow a generous timeout and do not retry. Read-only, NC only.

Should my agent pay this x402 endpoint? For any listing in nohumans.directory (id from /v1/discover), one call returns pay, caution or avoid with plain reasons: probe history and latency, whether its payment address is stable, whether we bought from it ourselves and it delivered (with the on-chain tx), its on-chain payments in the last 30 days, and whether the live price matches the listed one. Check before spending on an unfamiliar paid API.
