Contracts

🚧 In Development

This component is currently under active development. The API might change in future releases.

Contracts in ExtractThinker are Pydantic models that define the structure of data you want to extract. They provide type safety and validation for your extracted data.

Base Contract Implementation

from pydantic import BaseModel


class Contract(BaseModel):
    pass

Basic Usage

from extract_thinker import Contract
from typing import List, Optional
from pydantic import Field

class InvoiceLineItem(Contract):
    description: str = Field(description="Description of the item")
    quantity: int = Field(description="Quantity of items")
    unit_price: float = Field(description="Price per unit")
    amount: float = Field(description="Total amount for line")

class InvoiceContract(Contract):
    invoice_number: str = Field(description="Invoice identifier")
    date: str = Field(description="Invoice date")
    total_amount: float = Field(description="Total invoice amount")
    line_items: List[InvoiceLineItem] = Field(description="List of items in invoice")
