Random Weighted

by Solgiery Random in Onchain & crypto

x402 APIPassing, checked 4 h ago

Select one original index and item with probability weight divided by total weight. Weights must match items and be integers from 0 to 1000000000; at least one must be positive. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

How to call it

# See the payment challenge (nothing is charged)
curl -i -X POST "https://api.solgiery.com/v1/random/weighted" \
  -H "content-type: application/json" \
  -d '{"items":["a","b","c"],"weights":[1,2,0]}'
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),
);
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? Preflight it first for $0.005:
