TLDR;

TLDR; Covalent has introduced a list of Class B endpoints under the XY=K family which provide the richest and most robust on-chain DEX data available today. The Unified xy=k endpoints return all the required data for any UniswapV2-like protocol such as SpiritSwap, Pangolin, SushiSwap and more, on a variety of blockchains, enabling developers to access these protocols in a matter of minutes.

What You Can GET with xy=k:

• Get XY=K pools
• Get XY=K pools by address
• Get XY=K address exchange balances
• Get XY=K Network Exchange Tokens
• Get XY=K Single Network Exchange Token
• Get XY=K Transactions for Account Address
• Get XY=K Transactions for Token Address
• Get XY=K Transactions For Exchange
• Get XY=K Ecosystem Chart Data
• Get XY=K Health Data

TLDR; Today, we at Covalent are excited to launch a new reference documentation experience for our Unified Blockchain APIs. This new product is a complete re-thinking of the experience after speaking with thousands of developers who have come to rely on the Covalent API for their everyday blockchain data needs.

Some highlights of the new product:

• try the live API directly from the browser
• the analyst mode displays JSON responses with a spreadsheet interface
• built-in i18n features with Russian, Korean & Chinese language support and more languages to be added soon
• quick start templates that showcase various use-cases of the API
• new xy=k class B endpoints for Uniswap-like exchanges on various blockchains

Despite all the progress we’ve made in crypto tooling the last couple of years, one difficult task remains unsolved: extracting data from blockchains. Blockchain data is messy, disorganized and time-consuming even for an experienced engineer. Today, we are excited to announce a software development kit (SDK) to query data from the Ethereum blockchain – a problem we’ve been trying to solve for many years. We’ve been dogfooding the SDK internally for the last few months and used it to instrument over 20 DeFi protocols supporting over a dozen customers and thousands of users.
