Blockchain.com vs Coinlore
Blockchain.com's free Explorer API returns JSON data for Bitcoin blocks, transactions, and addresses with no signup or key, alongside a Statistics/Charts API, an Exchange Rates API, and a WebSocket feed for real-time block and mempool notifications. Browser callers can opt individual GET requests into CORS by appending a cors=true parameter; this read-only data API is a separate product from Blockchain.com's API-key-gated Exchange trading API.
Coinlore offers a free, keyless REST API for current prices, market cap, volume, and exchange ticker data across thousands of coins, aimed at hobby projects and simple price widgets rather than trading infrastructure. There is no paid tier or authentication layer — every endpoint is open and JSON-only.
