Block Lottos vs Solana JSON RPC

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.

Solana's public JSON-RPC clusters expose the full read/write RPC surface — accounts, transactions, blocks, and WebSocket subscriptions — with no signup or API key required. They're free to call, but Solana's own docs are explicit that the shared public endpoints are rate-limited to roughly 100 requests per 10 seconds per IP and are not intended for production traffic, pointing serious usage toward a dedicated third-party RPC provider instead.
