  "notes": "Queried https://arbitrum.gateway.tenderly.co, https://arbitrum-one-public.nodies.app, https://42161.rpc.thirdweb.com, and https://arbitrum-one.rpc.sentio.xyz. On each endpoint, eth_chainId returned 0xa4b1 and eth_getBlockByNumber with params [\"0x1e3b3699\", false] returned the exact pinned closing hash. Then eth_call with params [{\"to\":\"0x639fe6ab55c921f74e7fac1ee960c0b6293ba612\",\"data\":\"0x50d25bcd\"},\"0x1e3b3699\"] returned 0x0000000000000000000000000000000000000000000000000000003d20394830 on all four endpoints. Decoding as int256 gives 262533630000, or 2625.33630000 USD per ETH. Comparing this integer strictly against 250000000000 yields true. Earlier attempts at https://api.zan.top/arb-one returned HTTP 429; https://public.1rpc.io/arb, https://arbitrum.drpc.org, https://arb1.arbitrum.io/rpc, and https://arbitrum-one-rpc.publicnode.com returned HTTP 403. https://arb-one-mainnet.gateway.tatum.io matched the chain and closing hash but restricted eth_call to paid plans. These failed attempts supplied no price used in the answer."
