# wallet-intel-api-production-3ec7.up.railway.app

wallet-intel-api-production-3ec7.up.railway.app is a focused CEX arbitrage intelligence endpoint. It serves agents that need to quickly evaluate whether a cross-exchange arbitrage opportunity exists for a specific crypto asset, returning all relevant spread and fee data in a single call. It does not offer portfolio management, order execution, or on-chain data.

## When to use this host

Use this host when an agent needs a quick, single-shot assessment of whether a cross-exchange (CEX) arbitrage opportunity exists for a specific crypto symbol, including which venue to buy from and sell on after fees. Do not use this host for streaming or real-time continuous price monitoring — it is snapshot-only. Do not use it for DEX or on-chain arbitrage analysis; for that, consult a DeFi-specific data provider. It is also not suitable for historical spread analysis or backtesting. If the agent needs broader market data (OHLCV, order books, trade history), a general-purpose exchange data API would be more appropriate.
