WGO Data API

WGO provides daily BTC and ETH data for two focused questions:

1. Is ETF capital flowing in or out now, and has that direction persisted?
2. Is the cumulative long-term-capital proxy increasing or decreasing?

It also exposes daily on-chain fundamentals, realized liquidation history, and a sampled estimate of potential liquidation zones. The API is designed for reports and historical comparison, not order execution.

Coverage

Dataset	Assets	Granularity
US spot ETF aggregate	BTC, ETH	Asset × US trading day
US spot ETF funds	BTC, ETH	Fund ticker × US trading day
On-chain fundamentals	BTC, ETH	Asset × UTC day
Realized liquidations	BTC, ETH	Asset × UTC hour or day
Potential liquidation zones	BTC, ETH	Latest sampled position snapshot

ETF data is not tick-level data. The finest available ETF flow record is one fund ticker for one trading day.

Research data, not execution data

Do not treat the service as an execution feed, order-flow feed, identification of actual investor types, or a complete market-wide liquidation order book.
