Openai- responses api - web-search tool - Cannot pick the correct price from a website

I am using model 4o and the web search tool in open ai api to fetch the price of a product from a website. It seems to work well for some but not for others.
Even though it gives the correct url for the product , it just gives the wrong price both when using api and playground.
Below is my code:

class ProductEvent(BaseModel):
Product_url: str
Brand: Optional[str] = None
SKU_name: str
Product_description: Optional[List[str]] = None
Regular_price: Optional[str] = None
Promo_price: Optional[str] = None
Confidence: Optional[str] = None

client = OpenAI(api_key=openai_key)

instructions = “”" You are a specialist in sourcing pricing data from retailers.

                        Task:
                        Locate the product corresponding to the provided SKU only on the website provided.
                        Once identified, extract and return the result as a valid JSON containing following fields:
                       {
                          "product URL": "the product URL from the search result"
                         " brand": "the brand as found on the website"
                          "SKU name": "the SKU name as found on the website"
                          "product description": "product description as found on the website"
                          "regular price": "regular price as found on the website without the currency symbol, provide only the number, make sure the price is correct"
                          "promo price": "promo price as found on the website (if applicable, NA otherwise)"
                          "confidence": "level of confidence that the search result reflects the same product as the one provided"
                          }

                        Output Requirements:
                        1.Ensure the JSON is valid and complete (i.e., properly closed braces/brackets, no trailing commas).
                        2.if the domain does not contain any SKU that resembles the product, please return "No result" """

return event

Apply the function to each row and store the results in a new DataFrame

results = df_input.apply(process_row, axis=1)
results_df = pd.DataFrame(results.tolist())

This is my input

my output
