LINK token uses

The utility token is used for a variety of purposes including incentivizing data accuracy, keeping contracts stable, and rewarding nodes for validating transactions.

Reading Chainlink with Crypto APIs

Chainlink is issued on ERC-20 and settles on Ethereum. Crypto APIs reads it the same way it reads every other token on those networks — one REST call for balances, transfers and contract metadata, with no node to run and no separate integration per chain.

Token transfers

List full Chainlink token transfer history for any token contract or address, with pagination and real-time updates.

Token balances

Read current Chainlink token holdings for any address in a single call.

Contract metadata

Get token contract details — symbol, name, decimals, and total supply — for any supported token.

Frequently Asked Questions

Which blockchain does Chainlink run on?

Chainlink settles on Ethereum. Reading its balances and transfers means calling the ERC-20 contract rather than the address endpoint you would use for the chain's native coin.

What kind of token is Chainlink?

It is a token on the ERC-20 standard.

Can I test Chainlink without spending real funds?

Yes — the same endpoints serve Ethereum's Sepolia testnet, so you can build and verify an integration end to end before you touch mainnet.

How do I read Chainlink balances and transfers?

Use Address Latest for current state and recent activity — it needs no setup and answers for roughly the last 14 days. For a full history, Address History requires the address to be synced first, which then bills per address per day for as long as it stays synced.

What does reading Chainlink data cost?

It depends on the endpoint family rather than on Chainlink itself: single-record calls are charged per request, while list endpoints are charged per page returned, and a synced address adds a daily monitoring charge. The pricing calculator has the current per-chain figures.
