How this service works
Generate cryptographically secure randomness: passwords with charset rules, hex keys of any byte length, and uniform random integers (rejection sampling, no modulo bias). Never use Math.random for secrets. Use this when an agent needs to cSPRNG passwords, hex keys and uniform integers.
Output
Returns a single generated value: a random password string matching the requested charset rules, a hex-encoded key of the specified byte length, or a uniform random integer within the specified [min, max] range. The response includes the generated value and metadata about the generation parameters used.
Example use cases
Secure API key generation
“Generate a cryptographically secure 32-byte hex key I can use as an API secret — make sure it's CSPRNG, not Math.random.”
Random integer for token IDs
“Give me a cryptographically secure random integer between 100000 and 999999 with no modulo bias, I need it for a one-time token.”
Strong password for user account
“Create a secure random password that's 16 characters long with uppercase letters, digits, and symbols for a new user account.”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/crypto/random-generator?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an agent needs cryptographically secure randomness — passwords, hex keys, or integers — rather than language-model-generated pseudo-random values or insecure Math.random. Prefer this over asking the LLM to generate a password, which is neither random nor secure. This endpoint guarantees CSPRNG quality with no modulo bias for integers and full charset control for passwords.
Side effects
- Missing required 'mode' parameter returns a 400 error
- Invalid mode value (not 'password', 'hex', or 'int') returns a 400 error
- For 'int' mode, missing min or max returns an error
- min greater than or equal to max causes a validation error
- Length of zero or negative for password/hex modes returns an error
- Payment not provided or insufficient (x402) returns a 402 Payment Required
