To build a Crypto Wallet like Coinbase you need to integrate and setup all the coins you intend to support. The more coins you integrate , the more developers and server costs you will have.
Using Crypto APIs, you can start with any of the supported protocols at once and rely that Crypto APIs is going to add new protocols all the time.
Using Blockchain API, you can generate a hot wallet for each user, get a notification for all wallet events, auto forward the funds to a cold wallet, check the balance, check wallet transactions, etc.
Using Crypto Market Data APIs, you can get cryptocurrencies and FIAT current prices.

The Unconfirmed Transactions Endpoint returns an array of the latest transactions relayed by nodes in a blockchain that haven’t been included in any blocks.Documentation
Decode Raw Transactions EndpointGet general information Decode Raw Transactions Endpoint
We also offer the ability to decode raw transactions without sending propagating them to the network; perhaps you want to double-check another client library or confirm that another service is sending proper transactions.Documentation
Creating Transactions EndpointGet general information about Creating Transactions Endpoint
Using Crypto APIs, you can push transactions to blockchains one of two ways:Documentation
Sign Transactions EndpointGet general information about Sign Transactions Endpoint
The returned object is a hexadecimal string that represents the signed transaction. This hexadecimal is used by the Send Transactions Endpoint in order to broadcast the transaction into the Bitcoin blockchain.Documentation
Send Transactions EndpointGet general information about Send Transactions Endpoint
Transaction Send Endpoint allows users to broadcast the signed transaction to the Bitcoin blockchain.Documentation
New Transaction EndpointGet general information about New Transaction Endpoint
The New Transaction Endpoint combines the other three endpoints: Create, Sign and Send Endpoints. Users should provide the inputs and outputs fields with the corresponding data, as well as the fee and the wifs(private ECDSA keys) of the addresses. Therefore, the endpoint creates, signs and broadcasts the new transaction to the Bitcoin Blockchain. For more information, see the examplesDocumentation

Payment Forwarding informationGet general information about Payment Forwarding
One of the well-known benefits of cryptocurrency is the ability to allow users to partake in online commerce without necessarily requiring extensive setup barriers, like registering new accounts. In that spirit, our Payment Forwarding API is the easiest way to accept—and consolidate—payments securely without forcing your users to create accounts and jump through unnecessary loops. It’s also a generic way to automatically transfer value from one address to another.Documentation

Webhook Notification informationGet general information about Webhook Notifications
Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i.e., when a transaction is included into a block, or when an unconfirmed transaction is relayed through the network. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and Webhooks.Documentation
