# 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: []`.

**Endpoint:** `POST /api/v1/quote`\
**Auth:** Required (`Authorization: Bearer YOUR_API_KEY`)
