Introduction

With Subscan API, we provide a simple way to access the chain data of more than 90 substrate-based networks.

If you have any question or suggestion, please do not hesitate to contact our API support
via api@subscan.io.

The documentation was created with apidog.

API Keys

All Subscan API requests must be authenticated with an API Key. We provide flexible data access options to suit
different needs:

Free Plan: Designed for developers, researchers, and ecosystem enthusiasts to build and explore at zero cost.

Pro Plans: High-performance API services with expanded quotas and dedicated support for production environments.

Action Required: Visit https://pro.subscan.io/ to register your account and generate your required API key.

Service Status

The service status of Subscan API can be found on our status page.

Service Level Agreement

Subscan provides our customers the Service Level Agreement (SLA), which includes Monthly Uptime Percentage
commitment for multiple networks. Please contact us (api@subscan.io) for more information.

API Endpoints

Please notice before you get started:

The following endpoints list is maintained manually and it might be outdated. In fact, every individual network
supported on Subscan.io will have available API endpoint as well. The endpoint naming convention
is https://$NETWORK_NAME.api.subscan.io where the $NETWORK_NAME is the same as the subdomain of the corresponding
network on Subscan.io.

All the endpoints are forced to HTTPS only. Please make sure you use https:// with the API hosts.

SLA covered endpoints are shown on our service status page. Several networks are
excluded from our SLA for now. It might because: 1) the network is a testnet, not as stable as a mainnet, or could be
reset in a relatively higher chance; 2) the chain RPC that Subscan relied on is maintained by others (e.g. the chain
developers). We may update the covered list in the future. Please let us know if you want to have other networks
included in the SLA.

The Status marked as live is production network, and it will be maintained continuously. The Status
marked as test is test network, which may be unstable. Some new features of Subscan will be updated on testnet
first.

All APIs documented here are specifically designed for Subscan UI. While they may undergo frequent updates,
we strictly avoid introducing breaking changes. In the rare event of a mandatory breaking change, we will issue
advance email notifications to all subscribers.
