Fix
Documentation fix

​
Transactions API — OpenAPI documentation fix

Fixed OpenAPI schema inconsistencies between documentation and implementation for the /transactions endpoints. No breaking changes — API responses remain unchanged, only the OpenAPI spec was corrected.Nullable fields corrected:
  • Fee: fungible_info, price, value marked as nullable
  • Refund: fungible_info, price, value marked as nullable
  • Transfer: price, value marked as nullable
  • Fungible Info: icon marked as nullable
Missing fields documented:
  • Transaction attributes: address, refund, delegations
  • Fungible Info: id
Migration: No client changes required. Clients using generated models should ensure they handle null values, as these were already nullable in practice.
