response = requests.post(url, json=payload, headers=headers)

print(response.text)
```

### Response

  "input_cost_per_million_tokens": 0.15,

}
```

### Additional Information
Creates a new pricing version for a model. Pricing drives every cost-aware feature on the platform — usage attribution, spend reporting, and [token budgets](https://docs.barndoor.ai/api-reference/llm-gateway/token-budgets/listBudgets) with a `cost_limit`.
