Some of the features you can use

Address Details

All transactions made from a particular address need to be able to have a proper tax report.

Transaction Details

Transaction details are needed when a transaction occurs - how much were spent for the fee, in total, how much is the change, etc.

HD Wallet (xPub, yPub, zPub) Details

Most hardware and software wallets are Hierarchical Deterministic (HD) wallets. We provide full details about HD wallets by extended public key which is the HD wallet public key. Sharing it with us doesn't affect the security of the funds.

Blockchain Events

Get callback notifications (webhooks) whenever there are any deposits or withdrawals to or from your addresses that you would like to be notified about.

How to build a portfolio tracker

1

Add a wallet without keys

Take an xPub or a list of addresses — read access only, nothing that can move funds.

2

Read current positions

Fetch balances and token holdings per address across every chain you support.

3

Fill in the history

Pull the full transaction record to compute cost basis and performance.

4

Price it

Combine on-chain amounts with exchange rates to show value in the user's currency.

Frequently Asked Questions

Address Latest

Which blockchains does the Address Latest API support?

The Address Latest API covers 35+ networks across EVM, UTXO, and account-based networks. EVM chains include Ethereum, Ethereum Classic, BNB Smart Chain, Polygon, Avalanche C-Chain, Tron, Arbitrum, Base, and Optimism; UTXO chains include Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, and Zcash; plus XRP, Solana, and Kaspa. Each is available on both mainnet and its testnet where one exists.

Does the Address Latest API support Solana?

Yes. Solana is supported by the Address Latest API through a dedicated Solana handler, on both mainnet and devnet. You can retrieve the current balance and latest transaction state for a Solana address in real time.

What can I retrieve with the Address Latest endpoints?

Address Latest returns the current on-chain state for a specific address in real time, including its balance and recent transaction activity. Depending on the blockchain, this includes confirmed and unconfirmed transactions, unspent transaction outputs (UTXOs) for UTXO chains, internal transactions for EVM chains, and the next available nonce for EVM accounts. It is designed for looking up an address's latest state rather than deep historical archives.

How is the Address Latest API priced?

Every API request consumes credits, and the exact amount depends on the endpoint and the blockchain, with the consumed amount returned in the x-credits-consumed response header. Cost scales by a per-blockchain multiplier relative to a baseline chain (Ethereum for EVM, Bitcoin for UTXO). After your monthly credit allocation is used up, usage continues automatically under pay-as-you-go billing.

Does Address Latest work on testnets as well as mainnets?

Yes. Address Latest works on both mainnets and testnets for the supported chains, so you can develop and test against networks like Ethereum Sepolia, Bitcoin testnet, and Solana devnet before going to production. Kaspa is the exception, offered on mainnet only.

Which blockchains does the Address History API support?

The Address History API covers two families of chains. On the account-based side it supports Ethereum, Ethereum Classic, BNB Smart Chain, Polygon, and Tron; on the UTXO side it supports Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, and Zcash. All of these are available on both mainnet and their respective testnets.

Does the Address History API support Solana?

Address History focuses on the EVM and UTXO chains plus XRP for time-ranged historical transaction data. Solana on-chain data (addresses, transactions, balances) is available through the Crypto APIs Solana endpoints; check the docs for the exact historical coverage per chain, as it varies by network.

Do I have to sync an address before I can query its history?

Yes. Address history requires you to first register (sync) the address you want to track, after which its full transaction history becomes queryable. You can add an address with the Sync Address endpoint, list your synced addresses, and later activate or delete them. Once synced, you can pull confirmed transactions, statistics, and token or internal-transaction data for that address.

How far back does the historical data go?

Address History returns the full history of a synced address from the Genesis block up to the present. For each address you can list all confirmed transactions (including in ascending or descending order, or from a given timestamp) and retrieve aggregate statistics across its entire history.

Can I get token transfers and internal transactions for an address?

Yes, on the EVM chains. For Ethereum, Ethereum Classic, BNB Smart Chain, Polygon, and Tron you can list an address's token transfers, its internal transactions, and the tokens it holds. UTXO chains such as Bitcoin and Litecoin instead expose transaction history and unspent outputs (UTXOs) rather than token or internal-transaction data.

What data does the Crypto APIs Market Data API return for a cryptocurrency?

It returns current asset details including live price, circulating and max supply, market capitalization, 24-hour trading volume, and token contract addresses across protocols. You can look up an asset by its symbol (e.g. BTC) or by its unique asset ID. Data is sourced from CoinMarketCap.

Does the Market Data API provide OHLCV candlesticks or order-book data?

No. The Market Data API provides current price and current asset-to-asset exchange rates only. It does not include OHLCV/candlestick history or per-exchange order-book data.

How do I get the exchange rate between two assets, like BTC to USD?

Use the exchange-rate endpoints, which return the current rate between any two assets. You can request the rate either by asset symbols (for example BTC to USD) or by the two assets' unique asset IDs.

How many assets does the Crypto APIs Market Data API cover?

The API covers approximately 14,600 crypto and fiat assets, sourced from CoinMarketCap. You can enumerate the full supported list via the list-supported-assets endpoint, which supports pagination and a filter for crypto or fiat asset types.

Can I look up assets by symbol or do I need an asset ID?

Both are supported. Asset details and exchange rates can be requested either by human-readable symbol (such as BTC or ETH) or by the asset's unique asset ID. Symbol-based lookups are convenient, while asset IDs disambiguate tokens that share a ticker.
