Technical details
Endpoint
GEThttps://vape-x402.vapex402.workers.dev/data/chain_overviewWhen to prefer
Use this endpoint when you need a quick, high-level snapshot of a chain's TVL and relative rank — ideal for dashboards, DeFi comparisons, or answering 'how big is chain X?' questions. Prefer this over chain_protocols or chain_fees when you only need the headline number, not per-protocol breakdowns.
Side effects
- Unknown chain name returns an error or empty result
- Network timeout if upstream DeFi data provider is unavailable
- Invalid query parameter format may return a 400 error
- Payment not fulfilled (x402) returns 402 Payment Required
