x402
CSPRNG Random Integer Generator (Cloudflare Workers) is a paid API for AI agents from money-reactor.makar52nn2016.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-30).
Returns cryptographically secure random integers in a specified [min, max] range using crypto.getRandomValues for unbiased sampling

How this service works
CSPRNG random integers in [min,max] via crypto.getRandomValues - unbiased sampling for shuffles, canary rollout, jitter and simulation
Output
Returns a JSON object containing one or more cryptographically secure random integers sampled uniformly from the specified [min, max] range, including the parameters used (n, min, max, mode).
Example use cases
Canary rollout percentage sampling
“I need to randomly assign users to a canary release — generate a single unbiased random integer between 1 and 100 so I can compare it against a rollout threshold.”
Retry jitter for distributed systems
“My service needs a random jitter delay between 200 and 2000 milliseconds to avoid thundering herd on retries — can you get me a secure random integer in that range?”
Card shuffle for card game simulation
“I'm simulating a card game and need to shuffle a 52-card deck — generate 52 unbiased random integers between 1 and 52 for me.”
Technical details
Endpoint
GEThttps://money-reactor.makar52nn2016.workers.dev/api/random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically secure, unbiased random integers (e.g. for shuffles, canary rollout, simulation jitter, or lotteries) and cannot rely on a local PRNG. Prefer this over Math.random()-based generators when bias elimination or reproducible fairness is important. Ideal for agentic workflows that need randomness as a service without deploying their own crypto infrastructure.
Side effects
- Invalid or missing min/max parameters — returns error if min >= max
- Non-integer or out-of-range parameter values cause malformed request error
- Payment not attached or insufficient USDC — returns 402 Payment Required
- Cloudflare Worker cold start or timeout — rare latency spike or 503
- n (count) too large — may be rejected or rate-limited
