Request Quote
Get routing quotes for swaps. The public response is intentionally slim: quoteId, expiresAtMs, and route summaries.
For same-chain routes, provider is a convenience alias when the route resolves to one public provider label. For cross-chain or other multi-step routes, prefer providers, bridgeProvider, and stepCount.
If no viable route exists for the requested pair, the endpoint still returns 200 with routes: [].
