What is Cardano?

Cardano is a blockchain that utilizes a proof-of-stake consensus algorithm, which is more environmentally friendly compared to the proof-of-work algorithm used by Bitcoin. As a third-generation blockchain, it offers solutions to the limitations of first and second-generation blockchains and has seen a significant increase in capitalization in 2021.

The latest era of Cardano, known as the Voltaire era, introduced a decentralized voting and treasury system, allowing network participants to vote on proposals and fund development activities. This allows Cardano to become a self-sustaining and community-managed network.

The Cardano team also announced the creation of a new sidechain called Midnight, which offers zero-knowledge-proof smart contracts using a programming language that most developers are familiar with. Users can choose between complete privacy or partial privacy, allowing access to some data.

What is a Cardano API?

Cardano APIs allow developers to easily build and integrate applications with the Cardano blockchain, making it easier for users to access the various functionalities of the network.

Some examples of the use of Cardano APIs include:

Sending and receiving transactions: Developers can use Cardano APIs to create and sign transactions and send them to the blockchain.

Querying the blockchain: Developers can use Cardano APIs to query the blockchain for information such as the current block height, transaction history, and account balances.

Interacting with smart contracts: Developers can use Cardano APIs to interact with smart contracts deployed on the blockchain, such as creating, executing, and querying smart contract data.

Wallet management: Developers can use Cardano APIs to create and manage wallets for users, allowing them to securely store and manage their cryptocurrencies.

Building decentralized applications (dApps): Developers can use Cardano APIs to build decentralized applications that run on the blockchain, such as decentralized exchanges, gaming platforms, and prediction markets.

Best Cardano API Providers

Our list of Cardano APIs is designed to help you explore the blockchain and access key information.

1. Bitquery

Bitquery is a blockchain data company that provides a suite of APIs for interacting with the Cardano blockchain. These APIs allow developers to easily access the data and functionality of the Cardano network, facilitating the creation of decentralized applications (dApps) and other tools that use the Cardano blockchain.

Bitquery’s Cardano Explorer as shown in the picture above provides a wealth of information for blockchain enthusiasts and developers alike. With its advanced features, users can easily access key data points such as address stats, and transactions. The API also includes a built-in GraphQL IDE, which allows users to write custom queries and extract the specific data they need.

A variety of transaction details are available through the API, including inputValue, outputCount, inputCount, index, hash, feeValue, and more.

Coinpath® by Bitquery is a set of blockchain money tracing APIs that uses a sophisticated mathematical algorithm to trace the flow of funds between blockchain addresses.

You can use it to retrieve information about the sender, including address, annotations, number of senders, and receiver details, and can be filtered by address, transaction count or date range.

For those looking to delve deeper into the world of blockchain data, you can specify asset details, you can easily extract relevant information about inputs and outputs, including the transaction hash, source, currency details (symbol, name, token ID), value, and addresses.

Want to visualize your data as a graph? We’ve got you covered.

Support for multiple blockchains: In addition to Cardano, Bitquery also supports 30+ other blockchain networks, such as Ethereum, Bitcoin, and Binance Chain.

By using the points system to charge you for what you request, we save you millions of dollars in business costs. Sign up for a developer account for free.

2. Blockfrost

Blockfrost is a blockchain API provider that offers an API for querying information on the Cardano blockchain, such as addresses, blocks and assets, and inspecting transactions. Additionally, it provides SDKs multiple languages including Node.js, Python, Ruby, C#, and Golang.

The company provides a free plan with a limit of 50,000 requests per day for accessing the Cardano Mainnet. They also have testnet for other networks like Milkomeda MainnetBETA and Milkomeda TestnetBETA and Tangocrypto

3. Koios

Koios is a decentralized and elastic query layer that allows developers to explore data on the Cardano blockchain in order to consume it within various applications, wallets, and explorers. It addresses the issue of high computational costs and large amounts of data associated with fetching live data from the blockchain, by providing pre-computed data that is shared across nodes.

The Koios provides a GoLang CLI as well. The Koios API is free to use and does not require registration, but it does have a monitoring layer to prevent spam requests that could cause high loads on the backends.

4. Blockchair

The Blockchair API allows developers to access and analyze data from 17 different blockchains, including Cardano. It offers various analytical capabilities, such as filtering, sorting, and aggregating data. With this API, you can create a multi-blockchain wallet that can request transactions, address data, and also broadcast transactions. Additionally, you can build analytical services that display blockchain statistics and visualizations.

The Blockchair API also provides dashboard endpoints, which allow you to retrieve information about various entities in a neat format from the API’s databases. Additionally, it has raw data endpoints, which enable you to retrieve raw information about various entities directly from the API’s full nodes. The free plan allows for 1440 requests per day.

5. Mesh

Mesh is an open-source library that provides a variety of tools to easily build decentralized applications (dApps) on the Cardano blockchain. It is closely tied to network updates and includes frontend components and React hooks to help developers create user interfaces for their dApps.

Mesh also includes intuitive APIs for performing complex transactions, multi-sig minting, staking ADA to stake pools, and interacting with smart contracts. Additionally, developers can use the Mesh CLI to set up new applications using one of the starter kits and can choose their preferred language and framework.
