Agent Tools (x402) — Random Integer Generator
x402
Agent Tools (x402) — Random Integer Generator is a paid API for AI agents from agent-tools-x402.t6y11a.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-01).
Returns one or more cryptographically verifiable random integers within a caller-specified range, backed by the drand beacon, via a pay-per-call x402 micropayment.

How this service works
Pay-per-call utilities for AI agents. Payments in USDC on Base via x402 v2; no accounts or API keys. Failed requests are never charged. No endpoint performs server-side fetching of caller-supplied URLs.
Output
A JSON object containing: an array of random integers (integers[]), the drand beacon metadata (round number, chainHash, signature, randomness string) that proves the randomness source, and a verification URL pointing to the public drand API round used to generate the values. The integers are drawn uniformly within the [min, max] range.
Example use cases
Lottery number picker
“Pick 6 random numbers between 1 and 60 for my weekly lottery draw — I want them to be verifiably fair so no one can claim they were rigged.”
Random game event roll
“Roll 3 random integers between 1 and 20 for my tabletop RPG game tonight — like three independent dice rolls.”
Random winner selection
“I have a giveaway with 200 entries numbered 1 through 200 — pick one random winner number for me, and give me something I can show people to prove it was fair.”
Technical details
Endpoint
GEThttps://agent-tools-x402.t6y11a.workers.dev/api/random?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically verifiable, publicly auditable random integers — not just pseudo-random — especially when fairness must be demonstrable to third parties (lotteries, raffles, games). It requires no API key or account setup, charges only $0.002 USDC per call via x402, and never charges for failed requests. Prefer it over PRNG-based alternatives when the verifiability of randomness matters, and over heavyweight VRF services when you need a lightweight pay-per-use utility.
Side effects
- Payment not provided or insufficient USDC — request rejected with 402, no charge
- Invalid query parameters (e.g. n > 100, non-numeric values, min > max) — 400 error returned
- n or bound values outside allowed ranges — 400 bad request
- drand beacon temporarily unavailable — upstream error propagated
- Network timeout to workers.dev — 5xx or connection error
