RPC Endpoint Registry Aggregator

WHAT IT DOES

The RPC Endpoint Registry Aggregator is a developer tool that aggregates all available RPC endpoints for EVM-compatible chains. It queries a local registry of public RPC URLs, organized by chain ID and network name, and returns a complete list of endpoints for any specified chain. This helps developers quickly find working RPC URLs for development, testing, and production without searching through multiple documentation sites or community forums.

HOW TO USE

Enter a chain ID (e.g., "1", "137", "42161") or a network name (e.g., "Ethereum", "Polygon", "Arbitrum") into the search field. Click "aggregate endpoints" or press Enter to query the registry. The tool displays the chain name, chain ID, and a complete list of available RPC endpoints. Each endpoint is shown as a copyable URL for easy integration into your project configuration.

TECHNICAL MECHANISM

The tool uses a built-in registry database of public RPC endpoints compiled from Chainlist, community resources, and official chain documentation. Each entry contains the chain ID, chain name, and an array of RPC URLs. The lookup algorithm first attempts an exact numeric match on chain ID, then falls back to case-insensitive substring matching on chain names. The tool returns all matching chains and their associated endpoints, which is particularly useful for networks with multiple mainnet/testnet variants. The registry includes endpoints for over 25 EVM chains, covering all major networks and testnets. The tool displays endpoint counts and organizes results in a clean card layout with copyable URLs. The registry is stored locally and can be updated through future releases of the tool.

WHAT IT CANNOT SEE

The tool cannot verify if the RPC endpoints are currently operational or responsive. It cannot determine endpoint reliability or uptime without testing. The tool cannot detect rate limits or request caps per endpoint. It cannot measure latency or performance without external testing. The tool cannot update the registry without new releases. It cannot include endpoints not listed in the registry database. The tool cannot validate endpoint security or authentication requirements. It cannot detect endpoint deprecation or discontinuation.

PLEASE NOTE

This tool is designed for Ethereum Virtual Machine (EVM) compatible chains only. The registry includes the most common public RPC endpoints but may not include all available endpoints. Some endpoints may require API keys or may have rate limits—check with the provider for details. The tool provides information only and does not test or validate the endpoints. Always verify endpoints before use in production applications. The registry is based on publicly available data and may become outdated; for the most up-to-date endpoints, refer to the Chainlist project or the respective chain's official documentation.
