Block Lottos vs dYdX
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.
dYdX is a decentralized perpetuals exchange that migrated from its StarkEx-based v3 to a Cosmos-chain v4 architecture, replacing the old exchange API with an open-source Indexer exposing markets, orderbooks, trades, and candles over REST and WebSocket. Anyone can run their own Indexer instance, but the public one at indexer.dydx.trade needs no signup for market-data reads — it's rate-limited rather than API-key gated.
