x402.donnyautomation.com/random
Cryptographically secure randomness for agents that are deterministic or sandboxed. Two modes: raw bytes (?bytes=1..1024, default 32, clamped) returning hex and base64url; or uniform integers (?min= and ?max= together, optional ?count=1..1000) rejection-sampled so there is no modulo bias. Errors: 400 bad_bytes for a non-integer, bad_range when max is not greater than min, range_too_large. Generated server-side, and the response says so - if nobody may have seen it, generate it yourself.
