Blockchain Infrastructure Provider 0x Rolls Out New Line of APIs

Exchange infrastructure provider 0x is rolling out a new set of application programming interfaces designed to provide crypto developers with tools to build financial products for fast trading, better prices and an improved user experience.

The new project, according to a statement, includes five APIs, among them “Swap API,” which connects developers to more than 100 exchanges, and “Tx Relay API,” which enables trades without gas fees. An API is a channel that allows two computers or software systems to communicate with one another.

The Thursday announcement "represents a big shift for us," explained 0x co-founder Will Warren in an interview with CoinDesk. The 0x team has already helped build several popular retail-focused crypto wallets like Coinbase Wallet, Robinhood Wallet and MetaMask, but with the new platform, the company is now better equipped to provide professional-grade tools to institutions.

"[Decentralized exchanges] technology has been a constant arms race to provide better pricing," Warren said. "Now there are a bunch of different aggregators and meta aggregators and providing the very best pricing and best execution is just something that is constantly a challenge because the competition isn’t resting and neither are we."

UPDATE: (April 20, 16:16 UTC): Updates 0x's name.
