We’re proud to open-source **ts-chainlink-datafeed**, a TypeScript library that gives developers access to real-time cryptocurrency prices from the blockchain. It's a cost-effective, reliable alternative to relying on traditional third-party APIs and has saved our clients and engineers countless hours of effort.

Say goodbye to spinning up a whole proxy for CoinGecko or CoinMarketCap when building your Web3 site. Now when it's time to deploy, you've got one less thing to monitor and scale up on launch day!

[❓](https://emojipedia.org/question-mark)Why?
---------------------------------------------

For any DeFi protocol, having access to accurate and timely price data is critical. Most builders depend on aggregated data from various sources, which can be expensive and unreliable.

`ts-chainlink-datafeed` provides a **simple,** **direct connection** to Chainlink - a leader in providing high-fidelity data crucial for smart contract operations.

🧑 Who Benefits?
----------------

`ts-chainlink-datafeed` is ideal for developers that need precise, real-time price data for assets listed on Chainlink. Prior to this library, doing direct Chainlink interactions was a huge annoyance for builders. It’s equally valuable for both backend and frontend applications.
