Polygon API

Polygon is a layer 2 Ethereum blockchain scaling solution that allows quick transactions and low fees, without sacrificing on security. It combines the best of Ethereum and sovereign blockchains into a full-fledged multi-chain system.

The Polygon API — build without running a node

Access Polygon blockchain data through one unified REST API: transaction and address data, balances, block data, and real-time webhooks for on-chain events — with no Polygon node to run and maintain. Start free and scale as you grow.

Blockchain data

Read Polygon transactions, addresses, balances, UTXOs, and block data through one REST API.

Real-time webhooks

Subscribe to on-chain events — incoming and outgoing transactions, confirmations, and mined blocks.

No node to run

Skip the infrastructure — managed, always-synced access with no node to operate or maintain.

Blockchain for a decentralized future

Polygon aims to contribute to a decentralized future by enabling developers to build dApps faster, safer and cheaper. By providing the needed infrastructure it fosters the growth of Web 3 applications.

Frequently Asked Questions

Which blockchain does Polygon run on?

Polygon settles on Polygon. Tokens live in their own contracts rather than in the account balance, so reading them means calling the token contract; and every transaction needs the account's next nonce, which the same API returns.

What kind of chain is Polygon?

It is an account-model EVM chain — every address has a single balance and a nonce.

Can I test Polygon without spending real funds?

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

How do I read Polygon 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 Polygon data cost?

It depends on the endpoint family rather than on Polygon 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.
