Call when an agent needs a CSPRNG value from local crypto
Call when an agent needs a CSPRNG value from local crypto. mode is int, bytes, or choice. bytes n is at most 64. choice picks from a comma-separated list of at most 100 items, with optional shuffle. An audit id is returned. There is no seed. No network. Send JSON {"mode":"int","min":1,"max":10}. Exact $0.001 USDC on Base. Try unpaid POST /v1/sandbox/random first.
