# Get on-ramp quote

`POST /v1/onramp/quote`

Delegated Contract Mode will be deprecated soon; new partners should use Managed Custody Mode. On-ramp is not yet generally available; this endpoint is documented for preview only. Returns a real-time quote for fiat token to USDC (with optional swap or bridge) based on BufferPool and limit rules. If isSupport is false or needLivenessCheck is true, guide the user accordingly before submitting.
