The free endpoints mentioned in the Build Environment section are rate limited and designed for end users to be able to interact with dApps, or deploy/call smart contracts. They are not suitable for usage by dApp UIs that scrape blockchain data continuously, or indexers (like the Graph).
If you are an active developer you should consider creating your own endpoint, and it is mandatory to do so for production deployments. Refer to how run an [archive node](/docs/nodes /archive-node/) for more information, or obtain an API key from one of our infrastructure providers, listed below:
OnFinality is a SaaS platform providing infrastructure services for the Polkadot community. Its mission is to support blockchain developers of all shapes and sizes by providing infrastructure services so they can focus on building the next dApp.
Blast is Bware Labs' API provider platform that aims to solve Web 3 infrastructure issues related to reliability and latency, by employing geographically distributed third-party nodes.
Pinknode is a Polkadot-focused Infrastructure-as-a-Service platform offering RPC service through globally distributed node architecture coupled with Kubernetes clustering and geo-location routing for increased reliability and reduced latency. You will be able to integrate into the Astar ecosystem with Pinknode API services within minutes.
