Endpoint
POSThttps://twin.unykorn.org/defi/chain-tvl-history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need per-day TVL granularity for a single blockchain over a medium-to-long historical window (up to 2 years). It is ideal for trend analysis, charting DeFi growth, or generating time-series reports for a specific chain. If you need cross-chain TVL comparison, multi-protocol breakdowns, or real-time snapshots, consider other endpoints in the same network.
Side effects
- Missing or unrecognized chain name returns an error or empty result
- Days parameter outside 2–730 range is rejected with a validation error
- Chain with no DeFi data tracked may return an empty or sparse series
- Payment failure via x402 protocol prevents access to data
- Upstream DeFi data provider outage may cause stale or unavailable data
