What we support
Crypto APIs supports top blockchain protocols, layers and tokens both for testnets and mainnets. We constantly add new protocols and emerging tokens. We also support different blockchain exchanges.
Using Crypto APIs with exchanges
Crypto APIs does not connect to exchange trading APIs. What it does is watch the chain: derive your deposit addresses from an xPub, get a webhook the moment a transfer confirms, and reconcile withdrawals against on-chain data — no API keys held at the venue, no custody. These pages show how that works for each one.
Frequently Asked Questions
How many blockchains and networks does the API serve?
35+ networks across 19 blockchains, counting each chain's mainnet and testnets separately. The lists on this page are generated from what the API actually serves, so a chain missing here is a chain we do not support.
Are testnets included, or do I need a separate plan?
Included, on the same endpoints and the same key. You change the network parameter and nothing else, which is what makes it possible to build an integration end to end before touching mainnet. A few chains are mainnet-only — Kaspa, for one — and their pages say so.
Which token standards can you read?
ERC-20 and ERC-721 on Ethereum, TRC-20 and TRC-721 on Tron, and BEP-20 on BNB Smart Chain. Balances, transfers and contract metadata are the same three calls whichever standard you are on.
What does coverage cost?
It depends on the endpoint family rather than the chain count: single-record calls are charged per request, list endpoints per page returned, and a synced address adds a daily monitoring charge. The pricing calculator has the current per-chain figures.
