| 31 | +Data extraction allows you to parse unstructured text and extract structured data using AI. This is useful for converting free-form text into typed objects that can be used in your application. |
| 32 | + |
| 33 | +The following example shows how to extract product details from an unstructured product description. The AI model will analyze the text and return a structured object containing the product name, summary, price, and category. |
| 34 | + |
| 35 | +```typescript title="Schema Definition" |
| 36 | +const schema = a.schema({ |
| 37 | + ProductDetails: a.customType({ |
| 38 | + name: a.string().required(), |
| 39 | + summary: a.string().required(), |
| 40 | + price: a.float().required(), |
| 41 | + category: a.string().required(), |
| 42 | + }), |
| 43 | + |
| 44 | + extractProductDetails: a.generation({ |
| 45 | + aiModel: a.ai.model('Claude 3 Haiku'), |
| 46 | + systemPrompt: 'Extract the property details from the text provided', |
| 47 | + }) |
| 48 | + .arguments({ |
| 49 | + productDescription: a.string() |
| 50 | + }) |
| 51 | + .returns(a.ref('ProductDetails')) |
| 52 | + .authorization((allow) => allow.authenticated()), |
