How this service works
On-chain reserves of centralized exchanges (Binance, OKX, Bybit, Coinbase...) from their published wallets: total and ex-own-token assets, net inflows/outflows over 24h, 7d and 30d, spot and derivatives volume and open interest. Sort by reserves or flows.
Output
Returns a list of centralized exchanges with their on-chain reserve totals (USD), reserves excluding their own native token (USD), net inflow/outflow figures for 24h, 7d, and 30d periods (USD), 24h spot trading volume (USD), 24h derivatives trading volume (USD), open interest (USD), and associated wallet addresses. Also includes metadata such as the sort order applied and data source attribution.
Example use cases
CEX solvency health check
“I want to check if Binance and OKX are showing any unusual reserve outflows lately — can you pull their on-chain reserves and show me the net flows over the last 7 days?”
Exchange ranking by reserve size
“Rank the top 15 centralized exchanges by total on-chain reserves, and also show me reserves excluding their own native tokens so I can compare apples to apples.”
Spot vs derivatives volume comparison
“Pull the latest on-chain data for major exchanges and sort them by derivatives volume — I want to see which CEX has the most active derivatives markets and highest open interest.”
Technical details
Endpoint
POSThttps://api.vextorium.com/cex-reservas-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain verified reserve data for centralized exchanges rather than self-reported figures, especially when monitoring for reserve outflows, comparing exchange solvency, or analyzing market activity across spot and derivatives. Prefer this over generic market data APIs when the on-chain provenance of reserve figures matters.
Side effects
- Unknown exchange name in 'buscar' field returns empty results or null entries
- Invalid 'orden' enum value causes request failure
- Server-side data freshness issues if exchange wallets are not recently indexed
- Rate limiting or payment failure returns non-200 response
- Null values for some fields when an exchange does not publish derivatives data
