🔌 RPC Providers

There are multiple RPC providers from which you can choose from. These providers will work as intermediaries to help you interact with the Avalanche network. You'll experience different latency levels depending on the provider's configurations. You can potentially use multiple providers for redundancy and balancing.

Mainnet RPC - Public API Server

There is a public API server that allows developers to access the Avalanche network without having to run a node themselves. The public API server is actually several AvalancheGo nodes behind a load balancer to ensure high availability and high request throughput.

Using the Public API Nodes

The public API server is at api.avax.network for Avalanche Mainnet and api.avax-test.network for Avalanche Fuji Testnet. To access a particular API, just append the relevant API endpoint, as documented here. Namely, use the following end points for each chain respectively:

HTTP

  • For C-Chain API, the URL is https://api.avax.network/ext/bc/C/rpc.
  • For X-Chain API, the URL is https://api.avax.network/ext/bc/X.
  • For P-Chain API, the URL is https://api.avax.network/ext/bc/P.

Note: on Fuji Testnet, use https://api.avax-test.network/ instead of https://api.avax.network/.

WebSocket

  • For C-Chain API, the URL is wss://api.avax.network/ext/bc/C/ws.

Note: on Fuji Testnet, the URL is wss://api.avax-test.network/ext/bc/C/ws.

Supported APIs

The public API server supports all the API endpoints that make sense to be available on a public-facing service, including APIs for the X-Chain, P-Chain, C-Chain, and full archival for the Primary Network. However, it doesn't support Index APIs, which includes the X-Chain API's getAddressTxs method.

For a full list of available APIs see here.

Limitations

The public API only supports C-Chain WebSocket API calls for API methods that don't exist on the C-Chain's HTTP API.

For batched C-Chain requests on the public API node, the maximum number of items is 40. We're working on to support a larger batch size.

The maximum number of blocks to serve per getLogs request is 2048, which is set by api-max-blocks-per-request.

Sticky Sessions

Requests to the public API server API are distributed by a load balancer to an individual node. As a result, consecutive requests may go to different nodes. That can cause issues for some use cases. For example, one node may think a given transaction is accepted, while for another node the transaction is still processing. To work around this, you can use 'sticky sessions', as documented here. This allows consecutive API calls to be routed to the same node.

If you're using AvalancheJS to access the public API, simply set the following in your code:

avalanche.setRequestConfig("withCredentials", true)

Availability

Usage of public API nodes is free and available to everyone without any authentication or authorization. Rate limiting is present, but many of the API calls are cached, and the rate limits are quite high. If your app is running up against the limits, please contact us or try using a community RPC provider.
