How this service works
DEX vs CEX arbitrage spread — the price difference between DEX and CEX with the fee-adjusted NET spread and execution direction, not two raw prices. Compares the most liquid DEX pair (DexScreener) to CEX spot (Binance/Bybit), subtracts taker+swap fees, and flags any profitable arbitrage opportunity. For arbitrage agents.
Output
Returns the fee-adjusted net spread between the most liquid DEX pair (via DexScreener) and CEX spot price (Binance/Bybit), subtracting taker and swap fees, along with the execution direction (buy DEX/sell CEX or vice versa) and a flag indicating whether the opportunity is profitable.
Example use cases
Example prompt
“Is there a profitable arbitrage opportunity for ETH right now between DEX and Binance — give me the fee-adjusted net spread and which direction to execute.”
Technical details
Endpoint
GEThttps://x402-endpoints.onrender.com/crypto/dex-cex-spread?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a single, pre-computed, fee-adjusted arbitrage signal rather than having to manually fetch DEX and CEX prices separately and calculate spread and fees itself. Ideal for arbitrage bots or agents that need an actionable buy/sell direction rather than two raw prices.
Side effects
- Unknown or unsupported ticker symbol returns an error
- Token has no liquid DEX pair on DexScreener — no data returned
- Token not listed on Binance or Bybit CEX — comparison unavailable
- Spread is negative after fees — no profitable opportunity flagged
- Service temporarily unavailable on Render cold start — latency spike or timeout
- Payment not accepted — x402 payment required before data is returned
