# Convert Document for RAG Ingestion

AI teams building retrieval-augmented generation pipelines use this recipe to convert source documents into clean markdown that chunks well and produces high-quality embeddings.

## APIs Used

Document to Markdown (1 credit per page)

## Prerequisites

You need an Iteration Layer API key. Get one at [platform.iterationlayer.com](https://platform.iterationlayer.com) during the 7-day trial.

For full integration guidance (SDKs, auth, MCP, error handling), see the [Iteration Layer Integration Guide](https://iterationlayer.com/SKILL.md).

## Implementation


```bash
curl -X POST https://api.iterationlayer.com/document-to-markdown/v1/convert \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file": {
      "type": "url",
      "name": "product-manual.pdf",
      "url": "https://example.com/docs/product-manual-v3.pdf"
    }
  }'
```

```typescript
import { IterationLayer } from "iterationlayer";

const client = new IterationLayer({ apiKey: "YOUR_API_KEY" });

const result = await client.convertDocumentToMarkdown({
  file: {
    type: "url",
    name: "product-manual.pdf",
    url: "https://example.com/docs/product-manual-v3.pdf",
  },
});

// Split markdown into chunks at heading boundaries
const chunks = result.markdown.split(/(?=^## )/m);
```

```python
import re
from iterationlayer import IterationLayer

client = IterationLayer(api_key="YOUR_API_KEY")

result = client.convert_document_to_markdown(
    file={
        "type": "url",
        "name": "product-manual.pdf",
        "url": "https://example.com/docs/product-manual-v3.pdf",
    }
)

# Split markdown into chunks at heading boundaries
chunks = re.split(r"(?=^## )", result["markdown"], flags=re.MULTILINE)
```

```go
import (
    "strings"

    il "github.com/iterationlayer/sdk-go"
)

client := il.NewClient("YOUR_API_KEY")

result, err := client.ConvertDocumentToMarkdown(il.ConvertDocumentToMarkdownRequest{
    File: il.FileInput{Type: "url", Name: "product-manual.pdf", Url: "https://example.com/docs/product-manual-v3.pdf"},
})

// Split markdown into chunks at heading boundaries
chunks := strings.Split(result.Markdown, "\n## ")
```
