Technical details
Endpoint
GEThttps://defi-api.agenticfi.wtf/api/swap/quoteWhen to prefer
Use this endpoint when an AI agent needs to compute how much of a destination token a user will receive before committing to a swap, especially for cross-chain routes or Base ecosystem trades. Prefer this over on-chain simulation when you need fast, pre-trade pricing and routing without gas costs. Best for agents building DeFi workflows that require a quote step before execution.
