https://www.alchemy.com/ is the recommended way to access optimism data.

Our three chains that fail most often are optimism, arbitrum, and solana, and alchemy supports all these. on optimism and arbitrum we are rate limited by the public prcs at a rate lower than blocks are produced. we pay for a solana node elsewhere, but that service seemingly can't deliver us full blocks fast enough. maybe alchemy can.
