CoinGecko vs Solana JSON RPC

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.

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.
