Hello Paradigmers!

In today's update (v 0.152.0) to Paradigm brings fresh improvements to elevate your trading experience:

OB: Standardized Quote ID Format Across Order Book Endpoints

All Order Book (OB) endpoints have been updated to consistently use string quote IDs (e.g., q_3Gx1QHUDLb5mXDXPOlzSa1j8WVJ). Previously, select endpoints still returned legacy numeric IDs, creating friction when correlating trades back to their corresponding quotes. This migration establishes a unified ID format across the entire API surface to simplify trade tracking and data alignment.

Affected Endpoints

• GET /v1/ob/trades & GET /v1/ob/trades/{trade_id}
  • quote_id now returns the string ID format (previously numeric).
• GET /v1/ob/orders/{order_id}
  • Nested trades[].quote_id array values now return the string ID format.
• POST /v1/ob/rfqs/{rfq_id}/quotes & PUT /v1/ob/rfqs/{rfq_id}/quotes/{quote_id}
  • The deprecated legacy_id field has been removed.
  • The primary id field remains as the standard string ID format.

Action Required

If your integration relies on storing, parsing, or matching numeric quote IDs, update your system to use the string ID format (q_...).

New Feature: Enhanced Trade Filtering

• GET /v1/ob/trades
  • Added support for quote_id and rfq_id query parameters. You can now filter trade results directly at the API level instead of paging through and filtering the full trade list on the client side.
