Public API Server
There is a public API server that allows developers to access the Dijets network without having to run a node themselves. The public API server is actually several DijetsNodeGo nodes behind a load balancer to ensure high availability and high request throughput.
Using the Public API Nodes#
The public API server is at https://dijets.ukwest.cloudapp.azure.com:443 for Dijets Primary Network. To access a particular API,
just append the relevant API endpoint, as described in the document
Issuing API Calls. Following are the end-points you can use for
each of the ternary chains respectively:
HTTP#
- For Utility Chain API, the URL is
https://dijets.ukwest.cloudapp.azure.com:443/ext/bc/C/rpc. - For Value Chain API, the URL is
https://dijets.ukwest.cloudapp.azure.com:443/ext/bc/VC. - For Method Chain API, the URL is
https://dijets.ukwest.cloudapp.azure.com:443/ext/bc/MC.
WebSocket#
- For Utility Chain API, the URL is
wss://dijets.ukwest.cloudapp.azure.com:443/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
Value Chain, Method Chain,
Utility Chain, and full archival for the Primary Network.
However, it doesn't support Index APIs, which includes
the Value Chain API's getAddressTxs method.
Limitations#
The public API only supports Utility Chain WebSocket API calls for API methods that don't exist on the Utility Chain's HTTP API.
For batched Utility 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 DijetsJS to access the public API, simply set the following in your code:
dijets.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.
