# Source-Agnostic Solution (Harmonization Feature)

The feature harmonizes Custom Bet odds with your single odds pricing, and you can use odds from SR or any other operator, ensuring consistent margin and pricing across all bet types. Using your Core odds as the foundation streamlines calculations, improves efficiency, and gives you complete control over Custom Bet pricing.

**Benefits**

* **Source-Agnostic: odds from any operator are allowed, maximizing your pricing flexibility.**
* **Consistency**: Aligns pricing logic across all bet types.
* **Efficiency**: Reduces manual configuration and margin mismatches.
* **Control**: You retain complete control over odds and margins via the operator providing odds or your core Sportradar odds setup.

#### 5. Integration Steps <a href="#sourceagnosticsolution-harmonizationfeature-5.integrationsteps" id="sourceagnosticsolution-harmonizationfeature-5.integrationsteps"></a>

You’ll need to send your odds for every single selection when you call the following endpoints: calculate & calculate-filter.

If odds are **not** provided for all selections, we’ll use the non-harmonization approach (**Custom Bet ladder** you selected in CTRL).
