Free Cardano Public API brought by!

Hello developers,

i am happy to tell you that starting on Friday the 3rd we will offer you a new, free and highly flexible api which you can use to build your application with. It will allow you to request Cardano blockchain data, as if it’s a local database.

The API and documentation is already online, but still not fully synced. If you’re building on Cardano at the moment, we would be glad to receive further feedback. If you miss use-cases in the documentation , let us know! We wil be happy to update them to make building your application easier!

A Free Cardano Public API - What can i do with it ?

Retrieve all Cardano blockchain data, as you could from a local database, but via REST. OData Syntax allows you to get the data you need for your application. Start building your application today, don’t deal with infrastructure. It is free to use and we even prepared example queries for you. To give you an impression of whats possible in the following you will see possible use-cases we have gathered for you. The API can be freely used by everyone. We offer an api for testnet and one for the mainnet . API Documentation is done in Swagger, to make it easy to try it out directly. If you’re new to Swagger you find an introduction to Swagger here.

Our testnet API is here:

Our mainnet API is here:

With a click on the Authorize button on the Swagger UI Enter in the field Value: the public api key ILoveCutyMals . Then click on Authorize. Swagger then automatically sends the X-API-KEY=ILoveCutyMals header in every request you try out. That makes it very easy to understand what you can do with the API.

Let us hear what you think about, we are eager to make it the API you need!


We have updated the server hardware and adjusted the database.
Requests related to NFTs (which is the biggest table at the moment), should now be much faster.

Check it out!
We also added new use-cases!

The following possibilities were added now:

We also improved the indexes on the db so that the queries for the large tables perform much faster.
