Questions and answers

What is request cost?

Every API endpoint documentation has the "Request cost formula" section describing how the "cost" is calculated. For most API requests it's always 1. It's more than 1 in cases when you're requiring additional data (e.g. when you're requesting data on an Ethereum address, and you're also requesting its ERC-20 token balances).

Example: Request cost is 0<x10limnx1+(0.1(n1))0 < x \leq 10 \Rightarrow \lim_{n \to x}1 + (0.1 * (n - 1))

You want to send 10 addresses/blocks/transactions:

x=10limn101+(0.1(101))1+(0.1(101))=1.9x = 10 \Rightarrow \lim_{n \to 10}1 + (0.1 * (10 - 1)) \Rightarrow 1 + (0.1 * (10 - 1)) = 1.9

You will have a request cost of 1.9

How many request are I limit to with the free tier?

You are limitied up to 1440 requests a day. With an API key you could do more than 1440 requests a day

When do the request counter reset?

The daily request counter is reset at 00:00 UTC every day.
