Technical details
Endpoint
POSThttps://coinrailz.com/x402/service/batch-quoteWhen to prefer
Use this endpoint when an AI agent or trading bot needs to compare prices across multiple DEXs in a single API call rather than querying each DEX individually. Ideal for price discovery, pre-trade routing, and arbitrage detection on supported blockchain networks. Prefer over single-DEX quote endpoints when best execution price is the priority.
Side effects
- Unsupported chain returns error or empty quotes array
- Invalid token addresses result in no quotes returned
- Token pair with no liquidity yields empty quotes
- Amount too small or too large for available liquidity
- Network timeout or DEX unavailability yields partial results
