Coinlore vs Mempool
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.
mempool.space runs an open-source Bitcoin block explorer and fee-estimation API — originally forked from Blockstream's Esplora backend and now maintained as its own mempool/electrs fork — answering over REST and WebSocket with no signup needed to read blocks, transactions, addresses, and the Lightning Network graph. It's free for public use, with a paid Mempool Enterprise tier adding unmetered access and multi-datacenter SLAs for heavier commercial traffic.
