Solana web3.js with FlexYield

Connection with httpHeaders against the Solana mainnet slug.

Install

npm i @solana/web3.js

Connect and call

import { Connection } from "@solana/web3.js";

const connection = new Connection("https://flexyield.io/rpc/solana_mainnet", {
  commitment: "confirmed",
  httpHeaders: { Authorization: "Bearer fy_your_api_key" },
});

console.log(await connection.getSlot());

Replace fy_your_api_key with a key from your dashboard (free tier at registration). Chain slugs: eth_mainnet base_mainnet arbitrum_one optimism_mainnet polygon_pos solana_mainnet — each has its own measured page.
