Block Lottos vs Gemini
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.
Gemini's REST and WebSocket APIs cover public market data (tickers, order books, trade history) alongside authenticated endpoints for order placement, account status, and FIX Drop Copy. Public market-data calls need no credentials, while trading and account endpoints require an HMAC-signed API key/secret pair with role-based permissions such as separate Trader and Fund Manager roles.
