Quick Start Guide

Core Workflow

Install dependencies: On first run, install the ADP CLI tool.
Authentication setup: On first run, execute adp config get to check credentials. If not configured, prompt the user to provide an API Key.
Get app list: On first run, retrieve the out-of-the-box app list via adp app-id list --app-type 0, find the invoice extraction app, and record its app_id (prefixed with ootb_). For subsequent runs, prefer adp app-id cache.
Execute extraction: Run adp extract url <URL> --app-id <invoice-app-id> or adp extract local <file-path> --app-id <invoice-app-id>.
Process results: Parse the returned JSON to extract structured fields such as invoice number, date, supplier, buyer, currency, tax amount, total amount, and line items.
Error handling: When a command fails, parse the stderr JSON to determine the error type and recovery action.

Scenario-to-Command Mapping

Single Invoice Recognition

Batch Recognition

Async Processing

Concurrency Limit: Free users support a maximum of 2 documents for concurrent processing, while paid users support up to 10 documents concurrently.

Step 1: Install ADP CLI

# Method 1: npm (recommended, cross-platform)
npm install -g @laiye-adp/agentic-doc-parse-and-extract-cli

# Method 2: Shell script (Linux / macOS, when npm is unavailable)
curl -fsSL https://raw.githubusercontent.com/laiye-ai/adp-cli/main/scripts/adp-init.sh | bash

# Method 3: PowerShell script (Windows, when npm is unavailable)
irm https://raw.githubusercontent.com/laiye-ai/adp-cli/main/scripts/adp-init.ps1 | iex

Or download prebuilt binaries from GitHub Releases.

Step 2: Get API Key & Configure Authentication

Global (all other regions): https://adp-global.laiye.com/
China Mainland, Hong Kong, Macau, and Taiwan: https://adp.laiye.com/

adp config set --api-key <your-api-key>
adp config set --api-base-url https://adp.laiye.com
adp config get

Step 3: Get the Invoice Extraction App ID

ADP provides out-of-the-box built-in extraction apps for global invoices/receipts, supporting multiple languages and currencies with no additional configuration required.

App Types

ADP apps are divided into two categories, distinguished by the app_type field:

| app_type | Type | Description | | --- | --- | --- | | 0 | Out-of-the-box (OOTB) | Platform built-in, app_id prefixed with ootb_, ready to use without creation | | 1 | Custom | User-created extraction apps with user-defined app_id |

Invoice recognition is an out-of-the-box app and can be queried using --app-type 0.

Query and Filter Invoice Apps

# Query OOTB apps only (recommended)
adp app-id list --app-type 0

# Or query all apps
adp app-id list

Find the app whose app_label contains "Invoice", "Receipt", "high accuracy", high-speed extraction in the returned list, and record its app_id:

[
  {
      "app_id": "ootb_*****d9e2",
      "app_label": [
        "Invoice",
        "Receipt",
        "global invoices",
        "high accuracy",
        "high-speed extraction"
      ],
      "app_name": "Invoice/Receipt",
      "app_type": 0
    }
]

In the example above, "app_id": "ootb_*****d9e2" is the global invoice extraction app. app_type of 0 indicates an out-of-the-box app; 1 indicates a custom app.

Cache App ID (Recommended)

After the initial query, prefer using cache for subsequent requests to avoid redundant API calls:

# Use cache for subsequent calls
adp app-id cache

Important: Each account's app_id is unique and fixed — it will not change unless the user explicitly deletes the app. It is recommended that the Agent save the invoice app's app_id in context and reuse it directly in subsequent calls.

Step 4: Execute Invoice Extraction

Single Invoice Extraction (URL)

adp extract url https://example.com/invoice.pdf --app-id <invoice-app-id>

Single Invoice Extraction (Local File)

adp extract local ./invoice.pdf --app-id <invoice-app-id>

Single Invoice Extraction (Base64)

adp extract base64 <base64-string> --app-id <invoice-app-id> --file-name <filename.ext>

Response Example

ADP automatically supports invoice recognition in 100+ languages across all regions globally and automatically detects currencies. Extraction results are returned as unified structured JSON. The response contains two types of fields: regular fields and table fields (line items).

The following example is a simplified format showing only core fields. The full response also includes field_confidence (confidence score) and references (source location) metadata — see "Common Field Structure" below for details.

Extraction Field Reference

Note: field_key and field_name are always returned in English. field_value is multilingual — its content reflects the language of the source document (e.g., Chinese invoices return Chinese values, Japanese invoices return Japanese values). Different regions/types of invoices may return different field sets — the following lists all known fields.

Regular Fields:

| field_key | field_name (example) | Description | | --- | --- | --- | | invoice_number | Invoice Number | Invoice number | | invoice_date | Invoice Date | Invoice date | | due_date | Due Date | Payment due date | | currency | Currency | Currency (e.g., USD, EUR, GBP, JPY, etc.) | | supplier_name | Supplier Name | Supplier / seller name | | supplier_address | Supplier Address | Supplier / seller address | | supplier_vat_number | Supplier VAT Number | Supplier tax ID (e.g., Japan T-prefixed registration number) | | buyer_name | Buyer Name | Buyer / purchaser name (some invoices use customer_name) | | buyer_address | Buyer Address | Buyer / purchaser address | | customer_name | Customer Name | Customer / buyer name (alternates with buyer_name depending on invoice type) | | customer_vat_number | Customer VAT Number | Customer tax ID; returns "No result" when not recognized | | subtotal | Subtotal | Subtotal amount (before tax; some invoices use total_without_tax) | | total_without_tax | Total (excl. tax) | Total excluding tax (alternates with subtotal depending on invoice type) | | tax_amount | Tax Amount | Tax amount | | vat_rate | VAT Rate | VAT rate (e.g., 10%, 13%) | | total_amount | Total Amount | Total amount (including tax) | | amount_due | Amount Due | Amount due (may equal total_amount) |

Table Fields (Line Items):

| field_key | field_name (example) | Description | | --- | --- | --- | | line_items_item_code | Item Code | Product / item code; returns "No result" when not recognized | | line_items_description | Description | Product / service description | | line_items_quantity | Quantity | Quantity | | line_items_unit_price | Unit Price | Unit price | | line_items_amount | Amount | Line amount (some invoices use line_items_total_amount) | | line_items_total_amount | Total Amount | Line total amount (alternates with line_items_amount depending on invoice type) |

Common Field Structure

Each field object contains the following properties:

| Property | Type | Description | | --- | --- | --- | | field_key | string | Field identifier (e.g., invoice_number) | | field_name | string | Field name (e.g., "Invoice Number") | | field_values | array | List of extracted values (supports multiple values for fields that may have multiple entries, such as line items) | | field_values[].field_value | string | Extracted value (the actual content extracted from the document) | | field_values[].field_confidence | float | Confidence score for the extracted value (range: 0.0 to 1.0, where 1.0 indicates highest confidence) | | field_values[].references | array | List of reference points in the document that support the extracted value (e.g., bounding boxes, page numbers, or text snippets where the value was found) | | line_items_item_code | string | Code or SKU of the line item (if applicable) | | line_items_description | string | Description of the line item (if applicable) | | line_items_quantity | string | Quantity of the line item (if applicable) | | line_items_unit_price | string | Unit price of the line item (if applicable) | | line_items_total_amount | string | Total amount of the line item (if applicable) | | line_items_tax_rate | string | Tax rate for the line item (if applicable) | | line_items_tax | string | Tax amount for the line item (if applicable) |

How to distinguish field types: If table_values is present → table field, read from table_values; otherwise → regular field, read from field_values.

Step 5: Batch Processing & Async Mode

Batch Processing (Local Folder)
