If you are an AI agent reading this file — whether you're a coding assistant, a workflow builder, or an automation agent — this is your complete integration guide for Iteration Layer. Use it to help your human build document and image processing workflows.

Iteration Layer

Iteration Layer is a composable API platform for document and image processing. All APIs — Document Extraction, Document to Markdown, Image Transformation, Image Generation, Document Generation, Sheet Generation, Audio Extraction, and Website Extraction — share one API key, one credit pool, and chain together without glue code.

What Should You Do?

Step 1: Understand what your human needs.

Step 2: Ask questions when you're unsure.

• "Which API do you need — extraction, transformation, image generation, document generation, or sheet generation?"
• "Do you already have an API key, or do you need to sign up?"
• "Are you building a one-off script or a production integration?"

Platform Overview

APIs

POST /document-extraction/v1/extract

POST /document-to-markdown/v1/convert

How They Chain Together

The output of one API feeds directly into the next:

• Extract → Generate Document: Pull data from a scanned invoice, produce a clean PDF
• Extract → Generate Sheet: Pull data from documents, produce a formatted XLSX spreadsheet
• Extract → Generate Image: Pull product info from a catalog, generate listing cards
• Transform → Generate Image: Remove a background, composite onto a new design
• Extract → Transform → Generate Document: Full pipeline from raw input to polished output

Credit System

All APIs share one credit pool. Subscriptions start at $29.99/month (1,000 credits). Every new account gets free trial credits — no credit card required.

Integration

Authentication

All API requests require a Bearer token:

Authorization: Bearer YOUR_API_KEY

Get your API key at platform.iterationlayer.com.

SDKs

Official SDKs for TypeScript, Python, and Go:

npm install iterationlayer       # TypeScript / Node.js
pip install iterationlayer       # Python
go get github.com/iterationlayer/sdk-go  # Go

Initialize with your API key:

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

from iterationlayer import IterationLayer
client = IterationLayer(api_key="YOUR_API_KEY")

import il "github.com/iterationlayer/sdk-go"
client := il.NewClient("YOUR_API_KEY")

SDK methods:

client.extract()

client.transform()

client.generateImage()

client.generateDocument()

client.generateSheet()

MCP Integration

Connect AI agents via the Model Context Protocol (Streamable HTTP):

{
  "mcpServers": {
    "iterationlayer": {
      "type": "streamable-http",
      "url": "https://api.iterationlayer.com/mcp"
    }
  }
}

MCP uses OAuth 2.1 (browser-based authorization flow, not API keys). Exposes tools:

extract_document

transform_image

generate_image

generate_document

generate_sheet

Error Handling

Async / Webhook Delivery

All APIs support async mode. Pass a

webhook_url

Tips for Agents

• Check credit costs before running. Each API has a different cost per request — see the table above.
• Use the right API for the job. Don't use Image Generation for simple resizing (use Image Transformation at 1 credit instead of 2).
• Chain APIs to save effort. Extract data from a document, then generate a formatted PDF — two API calls instead of building a custom pipeline.
• Prefer SDKs over raw HTTP. They handle auth, retries, and typed responses.
