Block Lottos vs Mempool
Block Lottos runs on-chain lottery draws on Polygon and Base, and its public, keyless API exposes both the lottery side (live jackpot totals, draw stats, ticket-purchase transaction building, wallet ticket/prize lookups, and cryptographic draw proofs) and an advertising side for buying banner placements paid in USDC. Lottery tickets cost 10 POL on Polygon or 1 USDC on Base, and every response is plain JSON per its published OpenAPI spec, which also feeds an ai-plugin.json manifest for agent discovery.
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.
