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.

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

bash

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

bash

# 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

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/

bash

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

bash

# 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", or "Bill" in the returned list, and record its app_id:

json

[
  {
      "app_id": "ootb_*****c8d1",
      "app_label": [
        "Invoice",
        "Receipt",
        "Information Extraction",
        "High accuracy",
        "High-speed extraction"
      ],
      "app_name": "Invoice/Receipt",
      "app_type": 0
    }
]

In the example above, "app_id": "ootb_*****c8d1" 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:

bash

# 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)

bash

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

Single Invoice Extraction (Local File)

bash

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

Single Invoice Extraction (Base64)

bash

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`	Line Items	Line items table
`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 (machine-readable)
`field_name`	string	Field name (human-readable, localized based on document language)
`field_values`	array	Extraction result array (present for regular fields)
`field_values[].field_value`	string	Extracted value; empty string or "No result" when not recognized
`field_values[].field_confidence`	number	Confidence score (0.0–1.0); 0.0 indicates not recognized / low confidence
`field_values[].references`	array	Source location references (coordinates or text snippets)
`field_confidence`	number	Overall confidence score (table-level for table fields)
`table_values`	array[array]	Only present for table fields. 2D array: each row is a line item, each cell contains `field_name`, `field_key`, `field_values`

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)

bash

adp extract local ./invoices/ --app-id <invoice-app-id> --export ./results/

      "status": "success"
    },
    {
      "input": "invoice-002.pdf",
      "output": "invoice-002.pdf.json",
      "status": "success"
    },
    {
