# Alpha.Extractions

> Alpha feature endpoints for Extractions requests

## Overview

Alpha feature endpoints for Extractions requests

### Available Operations

* [Create](#create) - Submit an Extractions request

## Create

Extracts, computes, estimates or forecasts typed fields from a state string and image assets using an extraction-style System One model. Alpha: the shape is not stable.

### Example Usage

```go theme={null}
package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"github.com/OpenRouterTeam/go-sdk/models/components"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Alpha.Extractions.Create(ctx, components.ExtractionsRequest{
        Fields: map[string]components.Fields{
            "contacts": components.CreateFieldsList(
                components.ExtractionListField{
                    Items: components.ItemsText,
                    Type: components.ExtractionListFieldTypeList,
                },
            ),
            "days_to_pay": components.CreateFieldsEstimate(
                components.ExtractionEstimateField{
                    Max: components.CreateExtractionEstimateFieldMaxNumber(
                        120.0,
                    ),
                    Min: components.CreateExtractionEstimateFieldMinNumber(
                        0.0,
                    ),
                    Step: openrouter.Pointer(components.CreateExtractionEstimateFieldStepUnionNumber(
                        1.0,
                    )),
                    Type: components.ExtractionEstimateFieldTypeEstimate,
                },
            ),
            "due_date": components.CreateFieldsDate(
                components.ExtractionDateField{
                    Instructions: openrouter.Pointer("Issue date plus the net payment days"),
                    Type: components.ExtractionDateFieldTypeDate,
                },
            ),
            "invoice_number": components.CreateFieldsText(
                components.ExtractionTextField{
                    Type: components.ExtractionTextFieldTypeText,
                },
            ),
            "total": components.CreateFieldsNumber(
                components.ExtractionNumberField{
                    Decimals: openrouter.Pointer[int64](2),
                    Type: components.ExtractionNumberFieldTypeNumber,
                    Unit: openrouter.Pointer("USD"),
                },
            ),
        },
        Model: "cloudflare/clairic",
        ReferenceDate: openrouter.Pointer("2026-10-28"),
        State: "Invoice INV-2291 issued 2026-09-02, net 30. Contacts: Dana Ruiz, Priya Shah. Total $1080.",
    })
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
```
