The free endpoints mentioned in the Quickstart section are rate limited and dedicated to end users to be used to interact with dapps or deploy/call smart contracts. Thus, they are not suitable for usage by a dapp UI scraping blockchain data constantly or an indexer (like the Graph).
Please create your own endpoint for development or production referring to the Run an archive node section or get own API key for free/paid tier from one of our infra providers listed below:
