About this API
Moralis is a Web3 BaaS (backend-as-a-service) platform founded 2020, positioned to "let developers build Web3 apps without understanding complex EVM details". More high-level than Alchemy/Infura — the latter are mainly node access + some enhanced APIs, where developers still need to understand ABI/event logs/binary; Moralis provides business-layer APIs like "what NFTs are in my wallet", "this token's historical price", "listen for all transfer events on this contract". Strongest in cross-chain — one API covering Ethereum, BSC, Polygon, Avalanche, Solana, and 10+ chains; developers don't switch between node services. Free tier 40k compute units/month for small projects; commercial $49-249/month. Web3 games, NFT apps, wallet apps prefer Moralis for development speed.
