Introduction

With Subscan API, we provide a simple way to access the chain data of more than 10 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 Slate and hosted on GitHub.

API Keys

Get a free API key that includes higher quotas or start your trial with other available plans at https://pro.subscan.io/.

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:

  1. The following endpoints list is maintained mannually and it might be outdated.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.

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

  3. 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.

  4. 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.

Tutorial

Getting Start

1. Sign up to Subscan API Platform

To sign up for an account on the Subscan API Platform, enter your email address and password, and click SIGN UP.

To activate your account, verify your email address by clicking the link sent to your inbox.

2. Create API Key

Once verified, you’ll be taken to the management page where you can add API Keys, view status, and add new plans.

Every user could get a free plan for a trial. Free plan has a rate limit of 5 req/s and can only generate 1 API Key.

You can choose a more suitable plan according to your requirements.

3. Revoke API Key

You can choose to revoke an API Key.

This operation will be irreversible, so please operate with caution.

Payment Method

We accept the following payment:

Fiat (USD)

Crypto ($DOT)

Annual payment: 20% off the current total price.

Fiat

You could pay via Stripe. We support USD payment through credit card and bank.

Crypto

You could pay via our $DOT payment gate. The price of $DOT gets from Subscan’s $DOT price API.

Invoice

Invoices will be sent to the email in your profile once you finished the payment process.

Upgrade

  • You can upgrade your plan for a better experience.
  • The Free Plan couldn’t be upgraded now. We will provide free plan upgrade service in the near future

Subscribe

  • If you choose the Stripe payment method, automatic renewal will be turned on, and you will be able to renew without manual operation.
  • Here you can choose to turn auto-renewal on or off.

Renewal

  • Renewal operation is for $DOT payment method users and users who do not automatically renew.
  • You could choose Crypto payment or Fiat payment method.
  • After being paid successfully, the end time shall be extended.

Notice:

After updating the self-service payment system, users of the original standard plans(Including the Advanced Plan and Professional Plan) can use the self-service payment system for renewal.

Enterprise Plan users, please contact us, and we will handle the renewal for you.

Global Conventions

X-API-Key Header

The X-API-Key or x-api-key (case-insensitive) request header is the authentication method that Subscan API uses to determine the identity and rate limits.

Apply this form to get a free API key that includes higher quotas or start your trial with other subscriptions!

Rate Limiting

Each Subscan API key has a request quota, for example, 30 requests per second at most.

Currently, the quotas are global - shared across all APIs, all networks, and all client IP addresses as well. For instance, if an API key has a quota of 10 requests per second:

  • Client A requests https://polkadot.api.subscan.io/api/now with an API key;
  • Simultaneously, client B requests https://kusama.api.subscan.io/api/scan/metadata with the same API key.
  • After these 2 requests, only 8 requests with the same API key are allowed in that second.

Subscan API respects the Internet-Draft RateLimit Header Fields for HTTP. Through the headers of any response, it is simple to retrieve the limit (ratelimit-limit), remaining quota (ratelimit-remaining), and the seconds until the limit resets (ratelimit-reset) of your key. For example, send any request:

curl -isS -X POST -H "x-api-key: YOUR_KEY" https://kusama.api.subscan.io/api/now

An example of partial response headers:

ratelimit-remaining: 7
ratelimit-limit: 10
ratelimit-reset: 22

If the client reached the rate limit, all other requests in the time slot will be throttled with an HTTP 429 Too Many Requests response that contains a retry-after header.

An example of partial response headers:

retry-after: 4
ratelimit-remaining: 0
ratelimit-limit: 10
ratelimit-reset: 4

An example of response body:

{
  "message":"API rate limit exceeded"
}

HTTP Status Codes

The table down below lists several HTTP status codes that Subscan might respond.

Code Meaning
200 OK The request was handled without any error.
401 Unauthorized The credentials is either not found or invalid. Please refer to the message field in the JSON response for more detail.
404 Not Found The HTTP method or request URI was most likely wrong.
429 Too Many Requests The request hits the rate limit. Please request an API key with higher quotas.
500 Internal Server Error The servers could not respond your request due to an internal error. Find more information on our status page.
502 Bad Gateway The servers could not respond your request due to an internal error. Find more information on our status page.
503 Service Unavailable The services were under maintenance. Please try again later.
504 Gateway Timeout The servers could not respond your request due to an internal error. Find more information on our status page.
