How to track mining payouts

1

Watch your payout addresses

Register the addresses your pool pays into and get a callback on every confirmed transfer.

2

Reconcile what arrived

Read balances and recent activity to match payouts against what the pool reported.

3

Value it at the time it landed

Pull exchange rates so each payout is recorded at the rate on the day.

4

Move funds on your terms

Prepare and sign withdrawals yourself; we broadcast and confirm.

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 CryptoAPIs Blockchain Events API support?

Blockchain Events covers 35+ networks across EVM, UTXO, and account-based networks. The EVM chains are 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. Both mainnet and testnet networks are available for most chains.

Does the Blockchain Events API support Solana?

Yes. Solana is a supported chain for Blockchain Events on both mainnet and devnet, alongside XRP and Kaspa. You can subscribe to events and receive callbacks for Solana activity through the same unified subscription flow used for the EVM and UTXO chains.

What blockchain event types can I subscribe to?

You can subscribe to confirmed coin (native) transactions, unconfirmed coin transactions, internal transactions, and token transactions for an address, as well as newly mined blocks. Confirmed coin, internal, and token transaction events also offer an each-confirmation variant that fires on every confirmation. For UTXO chains, callbacks report direction (incoming or outgoing) based on input/output address matching.

How are event notifications delivered, and are the callbacks secure?

Events are delivered as HTTPS POST callbacks (webhooks) to a URL you register. The callback URL must use HTTPS and match a domain you verify in the Dashboard beforehand. You can optionally set a callback secret key so each request carries an HMAC-SHA256 x-signature header you can verify, and every callback includes an idempotencyKey so you can safely deduplicate.

What happens if my callback endpoint is down when an event fires?

CryptoAPIs retries failed callbacks with exponential backoff. Each callback allows a 5-second response timeout, and up to 5 retries follow roughly a 5, 10, 20, 40, and 80-minute schedule. If all retries fail, every subscription sharing that event type and callback URL is marked disabled, so you should monitor delivery and re-activate subscriptions as needed.

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.
