Base onchain read and utility toolkit
Written by Agorean from what the endpoint says about itself
Gives you onchain reads and utility functions for Base, in one API.
It bundles onchain reads for Base with basic utility functions: cryptographic digests, UUIDs, base64 encoding, and server time, alongside ERC-20 and native token balances, token metadata, block and transaction lookup, gas price, contract detection, and account nonce. Every route reads real data at call time and returns a clear error, rather than a silent zero, when a lookup misses.
WHEN TO USE THIS
When: I need a token or native balance read on Base
For example: Call the balance route for that address.
When: I need a quick UUID or a cryptographic digest
For example: Use the matching utility route.
When: I need to know if a lookup actually failed, not just returned zero
For example: Read the error response instead of assuming a zero balance.
When: I need a contract's basic details, or an account's nonce
For example: Use the contract detection or nonce route.
