# Domestic general bills
> Use ADP preset applications to extract fields from domestic general bills.
## Overview
Domestic general bills use the document extraction API.
```http theme={null}
POST /open/agentic_doc_processor/{tenant_name}/v1/app/doc/extract
```
The API returns extracted fields and classification results based on the preset application configuration.
For large files or longer-running extractions, create an asynchronous task first and use its `task_id` to query the result:
```http theme={null}
POST /open/agentic_doc_processor/{tenant_name}/v1/app/doc/extract/create/task
GET /open/agentic_doc_processor/{tenant_name}/v1/app/doc/extract/query/task/{task_id}
```
To verify an invoice directly from its invoice details, call the standalone invoice verification API:
```http theme={null}
POST /open/agentic_doc_processor/{tenant_name}/v1/app/invoice/verify
```
Provide the invoice number, invoice date, and tax-inclusive total. Use `YYYY-MM-DD` for the invoice date.
