CoinGecko vs dYdX
CoinGecko is one of the largest independent crypto data aggregators, tracking price, market cap, volume, and metadata for 17,000+ coins across 1,000+ exchanges without requiring registration for its free public endpoint. A Demo API key unlocks slightly higher limits, while paid Pro plans add exchange order-book data, NFT floor prices, and on-chain DEX data through the same JSON interface.
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.
