[Editor's Note] This guide will help blockchain enthusiasts and developers save a lot of time to overcome some of the most common development challenges.
Building applications based on blockchain or cryptocurrency exchanges often encounters many challenges:

- I have lived in Australia for 7 years. Where did the former Ali programmer talk about the gap between China and Australia?
- Why do we use GO language for blockchain?
- The existing public blockchain exceeds 50, and the number is still growing. Each chain has its own SDK and implementation features.
- Even if it involves simple interaction, developers need to have a deep experience for each blockchain.
- Developers and DevOps need solid security knowledge
- A blockchain is a huge dataset. To interact with a blockchain, you need to host the entire node, which is an additional cost to the server.
- There are many cryptocurrency exchanges (more than 400), each with its own software, database and API
Developers can use some of the API/SDK listed below to reduce the amount of time and server overhead costs:
The Crypto API is designed to unify the way developers interact with blockchain and cryptocurrency transactions.
It is one of the most effective solutions – focusing on blockchain, cryptocurrency exchanges, DApps, and API and SDK directions for various cryptographic applications.
The Crypto API provides integrated access to the blockchain at the head of the industry and implements access interfaces such as RestAPI, WebHooks, and WebSockets. The Crypto API provides insight into the main and test network details of key projects such as BTC, BCH, LTC and ETH, and will soon support EOS, Ripple, Stellar and NEO.
Developers can use APIs or SDKs in their programming languages and save a lot of time, and they don't need to host private nodes.
The Crypto API gives developers two choices (keep their own private key or host it to the Crypto API).
In addition, there is a module covering 200 cryptocurrency exchanges. The API allows developers to gain insight into more than 200 exchanges. Users can get real-time information about transactions and quotes, get time series data for OHLCV (open, high, low, close and volume), exact exchange rates between pairs of currency assets, and test and algorithm development historical data.
In addition to the public API, the Crypto API also has access to more than 100 private APIs, making it easier for developers to build trading software, arbitrage algorithms, algorithmic trading, and more.
The Crypto API uses CDN for data requests, multi-language SDK support, simplified API seamless integration installation process, and complete tag data delivery.
Developers can build games, games, handheld game consoles, exchanges, trade, DApps, explorers, and more, more easily and quickly.
CoinAPI provides a simple, fast and reliable unified data API for the cryptocurrency market.
The most powerful aspect is data standardization, access to data on demand via the HTTP RESTful API, real-time display of price volatility through WebSocket and FIX protocols, more simplified integration using various programming languages, backup of market historical data using a 20TB database, and Diverse API connection routing.
CoinAPI's CDN allows users to instantly connect to multiple locations, eliminating ping and speed issues with servers in the EU, US and Asia.
One problem with CoinAPI is that they don't have a unique ID, the currency symbol is confusing, and you can specify a date for a currency that is not bitcoin.
Leading cryptocurrency ranking provider CoinMarketCap also offers a set of APIs in its portfolio that allow users to generate real-time charts of markets, specific currencies and cryptocurrency lists. All data is transmitted in a few lines of code and can be easily integrated into a variety of websites.
Although it is widely used in the encryption industry, the current public API will be closed on December 4th and will evolve into a new and more powerful version, the Professional API. It will include real-time prices, winners/losers, social influences, news, watchlists, snapshots, and white paper searches.
Although the new version has new features, many sites and tools may not work if users don't migrate to the new Professional Edition.
This option is much more expensive than using the Crypto API service if we compare prices.
Blockcypher offers a range of APIs to meet everyone's needs. Blockcypher provides blockchain, address, wallet, transactions, microtransactions, metadata, analytics, assets, and Webhook APIs that work together.
The Blockchain API allows users to query blockchain and block generic data based on the cryptocurrency/blockchain resources they choose for the endpoint. The Address API collects information about the public address on the selected blockchain and presents it in a CSV file or HTML format.
Coinbase is one of the most popular trading platforms, and it also includes APIs that users can implement on their own websites. Coinbase easily integrates BTC, BCH, LTC and ETH into new and existing applications.
Coinbase's API has a variety of features, including the creation of BTC, BCH, LTC and ETH wallets and addresses, purchase / sale and send / receive these four cryptocurrencies. It also securely stores supported encryption keys in the wallet, retrieves real-time or historical price data, transaction push notifications, and various client libraries and mobile SDKs.
Coinbase's API allows e-commerce platforms to accept payments from multiple cryptocurrencies through customizable checkout gateways, gadgets and APIs.
CryptoTick is a website that can easily download 40TB of market history data from the cryptocurrency market. The data is time stamped with the UTC standard, which means that the trading algorithm can be tested more accurately. CryptoTick provides various types of processing data, such as OHLCV time series data created from active market data (transactions).
The Infura API provides access to the Ethereum network as well as high-speed IPFS interfaces. Infura provides load balancing nodes and intelligent architectures that store large amounts of data, and the hash values of files are stored on Ethereum.
Infura provides secure, reliable, scalable and easy to use and integrated APIs, and maintains Ethereum and IPFS infrastructure. Implementation code hidden behind Infura's RESTful, market data, and security APIs is portable on JSON RPC, Web3's Ethereum interface. For developers, this type of infrastructure can avoid scalability issues.
Blockchain WebHooks provides private hosting and management for a full-node network with the help of customized webhooks. Its transparent service will display all transaction data on the web URL submitted by the user. After the underlying sorting confirmation for these transactions on the blockchain, the webhook is immediately activated. A higher level of security is achieved through HTTPS callbacks, which also helps users accurately fill in URL data. Using this Webhooks service is a trusted strategy, and once an event occurs on a particular blockchain address, the system gets all notifications.
The CoinCap API provides real-time price information, volume and market value for over 1,000 cryptocurrencies. It collects information about resource costs and accessibility from a large number of commercial sectors. The CoinCap team announced the launch of its RESTful API 2.0 beta, which was launched on March 1, 2019. The new and improved API will display detailed information about assets, rates, exchanges and markets.
Finally, but at least in our list is Bitcointy, which provides average bitcoin price data from a variety of sources, covering legal currencies such as Euro, British Pound, Canadian Dollar, Japanese Yen and Renminbi. In addition, this API is free and does not limit the number of data requests. It coordinates specific measures to convert Bitcoin into any currency and collects exchange rates for all or a single source.
