How this service works
Cryptographically secure randomness: N random bytes as hex, a uniform integer in a range, or a batch of up to 100 values in one call. Use it when an agent needs unpredictable values for nonces, sampling, shuffles or test data and cannot trust its own generator.
Output
Returns a JSON object containing either a hex string of N random bytes, a single random integer within [min, max], or an array of up to 100 such values if count is specified.
Example use cases
Example prompt
“Give me 5 cryptographically secure random integers between 1 and 100, and also generate 32 random bytes as a hex string.”
Technical details
Endpoint
GEThttps://agent402.tools/api/random?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need cryptographically secure randomness rather than pseudo-random values — ideal for generating tokens, nonces, salts, or unbiased integer samples. Prefer over language-runtime Math.random() when security or statistical uniformity matters.
Side effects
- bytes parameter out of range (must be 1–1024) returns error
- min greater than max returns error
- count out of range (must be 1–100) returns error
- mixing bytes and min/max parameters may return error
- missing required parameters returns error
- payment not included or invalid returns 402
