PARSIQ is excited to be ETHDenver during BUIDLWeek! As a Meta Sponsor, we’re proud to be supporting everyone building in the space. Events like these only further prove that there are a lot of exciting things going on in the world of Web3.

PARSIQ always has the needs of developers in mind. We want to make their job as easy as possible! That’s why — already in 2023 — we’ve made it so our Tsunami API now includes the entirety of Arbitrum (both Classic and Nitro), launched our ABI Decoder, and greatly expanded the scope of our NFT Data Lake.

Being around so many devs at ETHDenver has inspired us to create a brand-new product to make the life of devs easier…

Today, we’re launching yet another time saving — and not to mention work and cost saving — tool, a JS Client for Tsunami API users!

And, in the spirit of BUIDLWeek, we’re offering up to 1000 free accounts to Devs who need access to Web3 data.

Our Tsunami API makes it easy to access Web3 data instantly! Curious to give it a try? Click here.

Tsunami API + JS Client

We’ve seen to it that our Tsunami API is easy to use. Access to it is available via RESTful APIs. Familiar to any developer, REST (Representational State Transfer) APIs are commonly used as an industry standard.

Yet, they still can sometimes be a hassle to set up. That is why we’ve launched our JS Client, or “Tsunami Client”!

What the “Tsunami Client” offers is a library of functions that we’ve ready-made for users of Tsunami. You can simply plug them into your project, and begin using them — essentially as short cuts to common actions — with no coding standing in your way.

What this means for developers is that we’ve taken away even more potential hassle standing in the way of the data you need. Now, you can get all your Web3 data in an instant, just provide your API key and start querying right away!

The Tsunami API makes it so you never have to think about requests and responses again — everything is strictly-typed and comes with code suggestions!

Take me to the code! The Tsunami Client source code can be found here, and the NPM package is available here.
