Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/defi/:chainWhen to prefer
Use this endpoint when you need a fast, chain-specific DeFi ecosystem snapshot including total TVL and protocol-level breakdown with recent momentum (24h change). Prefer it over generic crypto price endpoints when the user's question is specifically about DeFi protocol health, TVL rankings, or ecosystem composition on a particular chain.
Side effects
- Unsupported chain name returns an error or empty result — only base, ethereum, solana, arbitrum, polygon are supported
- Payment not fulfilled results in 402 response
- Chain parameter missing causes a 400 bad request
- Upstream data provider outage may return stale or empty TVL data
