The Power of the Blast API Front Page
Most APIs make you read documentation before you can see what they do. Blast API shows you before you even sign up.
The front page is a live demonstration. Enter a wallet address. Watch the data flow. Upload a CSV. See the grand total across 100+ chains. No sign-up. No wallet. No friction.
The Live Demo
Enter any wallet address and hit "Blast All Chains." Within seconds, you'll see a list of chains with balances, a pie chart, a bar chart, and a grand total — all in one view.
The CSV Dashboard
Upload a CSV with wallet addresses and emails. Blast API processes every single one across 100+ chains. You get a grand total, bar chart, pie chart, and a clickable list to drill down into any wallet's details.
The Time You Save
Checking your portfolio across multiple chains can take hours. With Blast API, it takes seconds.
