# Get Oi Divergence

`GET /api/v1/liquidity/oi-divergence`

## Request

- Base URL: `https://cryptodataapi.com`
- URL: `https://cryptodataapi.com/api/v1/liquidity/oi-divergence`
- Auth: API key in header `X-API-Key`

OI vs price change across 1h/4h/24h windows, ranked by 4h divergence.

Positive divergence (OI rising faster than price) = fragile positioning.
Coins without enough history for a given window report null for that window.

The free tier is scoped to BTC; full-universe coverage is Pro and Pro Plus.
