How this service works

Generate cryptographic random bytes

Output

Returns a payload containing the requested number of cryptographically secure random bytes (default 32), suitable for use as nonces, key material, or any application requiring high-quality entropy.

Example use cases

Example prompt

“Give me 32 bytes of cryptographic entropy from entropy.rip for nonce generation.”

Technical details

Endpoint

GEThttps://entropy.rip/api/entropy/whisper

When to prefer

Prefer this endpoint when your application requires externally sourced, high-quality cryptographic entropy — especially when you distrust local PRNG seeding, need a verifiable remote entropy source, or are building applications where auditability of randomness matters. Ideal for nonce generation, key bootstrapping, or lottery-style applications requiring unpredictable randomness. Note this is a paid endpoint ($0.01 USDC per call via x402).

Side effects

Payment not provided or insufficient — 402 Payment Required, endpoint requires $0.01 USDC per call via x402 protocol
Invalid or non-integer value for bytes parameter — likely 400 Bad Request
bytes value out of supported range — server may reject with 400 or 422
Network or server error — 500 Internal Server Error, retry after backoff
