How this service works

Landing page para tu negocio en 24 horas: textos, diseño para celular y botón de WhatsApp. Boceto gratis: ves la primera versión antes de pagar. USD 39 de lanzamiento.

Output

Returns a JSON object containing: a random integer within the specified range, an array of random integers (length = count), a hex string of random bytes, and metadata (min, max, bytes, source label indicating 'crypto.getRandomValues (CSPRNG)').

Example use cases

Secure token generation for auth flow

“I need a 32-byte cryptographically secure random hex string to use as a session token or nonce — can you generate one?”

Dice-roll simulation for game logic

“Roll 10 random integers between 1 and 6 for me, like rolling 10 dice, using a crypto-secure random source.”

Random sampling index picker

“Pick 3 random integers between 0 and 49 so I can randomly sample items from my list of 50 entries — make sure they're truly random, not pseudo-random.”

Endpoint

When to prefer

Choose this endpoint when you need verifiably cryptographically secure random values (CSPRNG-backed) rather than pseudo-random numbers, especially for security-sensitive use cases like token generation, nonces, or fair sampling. Prefer it over language-native Math.random() equivalents when tamper-resistance or auditability matters.

Side effects

bytes > 256 returns validation error
count > 100 returns validation error
count < 1 or bytes < 0 returns validation error
non-integer values for min/max/bytes/count may cause type errors
payment failure returns 402 Payment Required
