Base payment check. Returns pong after settlement.

Generate length cryptographically random bytes, encoded as lowercase hexadecimal. length defaults to 32 and may be 1 to 4096. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Uniformly select one original index and item from the input array. Equal values at different positions have separate chances. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Flip one fair coin. Returns heads or tails, each with probability one half. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Roll 1 to 1000 independent fair dice. Each result is an integer from 1 to sides inclusive; sides defaults to 6. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Generate 1 to 1000 independent random numbers on the 53-bit grid in [0,1); zero is included and one is excluded. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Generate 1 to 1000 uniformly distributed random integers between min and max, inclusive. Both bounds are required; min must not exceed max. Repeated values are possible. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Select count items as an ordered sample. replace defaults to false: each original index may occur once and count must not exceed the input length. With replace=true, draws are independent and indices may repeat. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Uniformly permute all input items. Returns each original index and its item exactly once; equal values remain distinct positions. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Generate one UUID version 4 using server-side cryptographic randomness. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Select one original index and item with probability weight divided by total weight. Weights must match items and be integers from 0 to 1000000000; at least one must be positive. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.
