Block Lottos vs MercadoBitcoin
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.
Mercado Bitcoin is Brazil's oldest and largest cryptocurrency exchange, operating since 2013 with spot trading across dozens of BRL pairs. Its v4 REST API and companion WebSocket service expose public market data — candles, order books, tickers — without authentication, while trading and account endpoints require an API key created from account settings. The API is free to use for individual developers.
