# RPC Gateway > RPC Gateway is a stable access layer between applications and blockchain nodes, with one App API Key, shared cached results for supported Endpoint-free RPC reads, and configurable Endpoint routing. The public documentation is English-only. Use the dashboard-provided Access Point rather than constructing a production domain. ## Start here - [Quickstart](https://rpc.aurpay.net/docs.md): Create an App, call its Gateway, and add an Endpoint for full RPC coverage. - [Endpoint-free RPC](https://rpc.aurpay.net/docs/endpoint-free-rpc.md): Use shared cached results for documented EVM, Solana, Bitcoin, Litecoin, and TRON reads before the Gateway selects an Endpoint. - [Authentication](https://rpc.aurpay.net/docs/authentication.md): Use, rotate, and protect App API Keys. - [Supported networks](https://rpc.aurpay.net/docs/supported-networks.md): Chains, networks, protocols, and access hosts currently exposed by RPC Gateway. - [Routing and reliability](https://rpc.aurpay.net/docs/reliability.md): Configure priority failover or weighted balancing across matching Endpoints, with bounded retries, Circuit protection, and response validation. - [Errors and recovery](https://rpc.aurpay.net/docs/errors.md): JSON-RPC and TRON HTTP API error contracts with recovery actions. ## Complete documentation - [Documentation index](https://rpc.aurpay.net/docs/llms.txt): Curated index of every machine-readable documentation page. ## Optional - [Human-readable documentation](https://rpc.aurpay.net/docs): Rendered documentation with navigation and search.
