Agent Dev Tools – Secure Random Number Generator
x402
Agent Dev Tools – Secure Random Number Generator is a paid API for AI agents from agent-dev-tools.frcompanycheck.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Generates one or more cryptographically secure random integers within a specified range, optionally with unique values and random byte output, paid per call via x402/USDC

How this service works
Fast deterministic developer utilities for AI agents, paid per call in USDC via x402 (no account, no API key): UUID v4/v7, secure random numbers, dice, MD5/SHA/HMAC hashing, base64/hex/URL/HTML encoding, JSON validation/formatting, QR code SVG, password generation, JWT decoding and text statistics. Pure computation, nothing stored. Errors are never charged.
Output
Returns a JSON object with an array of random integers ('numbers') within the requested min/max bounds, the min and max values used, and optionally a hex string of random bytes. Example: {numbers:[17,88,3,42,65], min:1, max:100, hex:null}
Example use cases
Lottery ticket number picker
“Pick 6 unique random numbers between 1 and 49 for a lottery ticket — make sure none repeat.”
Game dice roll simulation
“Roll 10 random numbers between 1 and 6 for a board game simulation, repeats are fine.”
Cryptographic nonce generation
“Generate a single random number between 0 and 2147483647 and give me 32 random bytes as hex for use as a cryptographic nonce.”

Endpoint
GEThttps://agent-dev-tools.frcompanycheck.workers.dev/v1/random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically secure random integers on demand with no API key or account setup, especially in agent workflows where frictionless per-call micropayment via x402/USDC is acceptable. Prefer it over free alternatives when auditability of payment-per-call is important, or when you need combined random integers plus random bytes in a single call. Not suited for high-volume bulk randomness where per-call cost adds up significantly.
Side effects
- count out of range (must be 1-1000) — request rejected, not charged
- bytes out of range (must be 0-256) — request rejected, not charged
- min >= max — invalid range error, not charged
- unique=true with count exceeding range size — impossible uniqueness error, not charged
- payment failure via x402 — 402 response, not charged
