Getting Started

Welcome to the Iteration Layer API documentation. This guide will help you get up and running in minutes.

Quick Start

1. Create an Account

Sign up at iterationlayer.com to create your account. You’ll receive free trial credits for each API to get started. Generate a global API key from the API Keys page — keys work across all APIs.

2. Make Your First Request

curl -X POST https://api.iterationlayer.com/document-extraction/v1/extract \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "files": [{"url": "https://example.com/invoice.pdf"}],
    "schema": {
      "fields": [
        {"name": "invoice_number", "type": "text"},
        {"name": "total_amount", "type": "currency"}
      ]
    }
  }'
import { IterationLayer } from "iterationlayer";
const client = new IterationLayer({ apiKey: "YOUR_API_KEY" });

const result = await client.extract({
  files: [{ type: "url", name: "invoice.pdf", url: "https://example.com/invoice.pdf" }],
  schema: {
    fields: [
      { name: "invoice_number", type: "TEXT", description: "The invoice number" },
      { name: "total_amount", type: "CURRENCY_AMOUNT", description: "Total invoice amount" },
    ],
  },
});
from iterationlayer import IterationLayer
client = IterationLayer(api_key="YOUR_API_KEY")

result = client.extract(
    files=[{"type": "url", "name": "invoice.pdf", "url": "https://example.com/invoice.pdf"}],
    schema={
        "fields": [
            {"name": "invoice_number", "type": "TEXT", "description": "The invoice number"},
            {"name": "total_amount", "type": "CURRENCY_AMOUNT", "description": "Total invoice amount"},
        ],
    },
)
import il "github.com/iterationlayer/sdk-go"
client := il.NewClient("YOUR_API_KEY")

result, err := client.Extract(il.ExtractRequest{
    Files:  []il.FileInput{il.NewFileFromURL("invoice.pdf", "https://example.com/invoice.pdf")},
    Schema: il.ExtractionSchema{
        "invoice_number": il.NewTextFieldConfig("invoice_number", "The invoice number"),
        "total_amount":   il.NewCurrencyAmountFieldConfig("total_amount", "Total invoice amount"),
    },
})
