Request a Soft Attestation Quote

post

https://api.gm.ondo.finance/v1/attestations/soft

A soft quote provides pricing information for mint or redeem operations without creating an actual attestation. Unlike the Request a Mint or Redeem Attestation endpoint, soft quotes:

Are not eligible for on-chain submission
Do not count against user limits (Active Notional Value, Session Notional Value, or Active Attestations)
Serve as pricing references for quote validation and user interface display
Do not include authentication fields such as attestationId, userId, expiration, or signature

This endpoint can be used to acquire estimated pricing without impacting trading limits or creating binding commitments.
