What you can build

Transaction details for payments, support and compliance

Confirm a payment

Check a customer's transaction by its hash: who sent it, who received it, the fee, and the block it was mined in.

Follow token movement

List the token transfers and internal transactions of an EVM transaction, the parts a plain transfer view leaves out.

Debug a contract call

Read the event logs of an Ethereum transaction to see what a contract emitted.

Endpoints

Every Transactions Data endpoint

Each operation links to its page in the API reference, with its parameters and responses. Paths take the blockchain and the network, so moving to another chain is a change of path.

Transactions Data works on 18 blockchains: Bitcoin, Ethereum, XRP Ledger, Ethereum Classic, Bitcoin Cash, Dash, Litecoin, Dogecoin, Zcash, BNB Smart Chain, Polygon, Tron, Solana, Avalanche, Arbitrum, Optimism, Base, Kaspa. Each chain's page lists its networks and its own endpoints.

Can I try Transactions Data for free?

Yes, for 14 days. The Blockchain API free trial includes Transactions Data and every other feature, with no card. It ends after 14 days or when its credits run out; after that, calls need a subscription, listed on the pricing page.

Does the Transactions Data API support Solana?

Yes. Solana is a live chain for the Transactions Data API, alongside XRP and Kaspa. You can retrieve detailed transaction data on Solana mainnet and its devnet network.

What data does the Transactions Data API return for a transaction?

It returns comprehensive details for any provided transaction, including the participating addresses (senders and recipients). This lets developers and businesses track and analyze blockchain activity and integrate transaction details into their applications. Coverage spans EVM, UTXO, XRP, Solana, and Kaspa chains.

Does the Transactions Data API cover Bitcoin and other UTXO chains?

Yes. UTXO chains are fully supported for transactions data, including Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, and Zcash. Both mainnet and testnet networks are available for these chains.

Can I query transactions on both mainnet and testnet?

Yes. Most supported chains expose both a mainnet and a test network, such as Ethereum mainnet and Sepolia, Bitcoin mainnet and testnet, and Solana mainnet and devnet. Kaspa is currently mainnet only.
