Load ABBYY data to DuckDB

ABBYY Vantage is an intelligent document processing platform that provides REST APIs for submitting documents and retrieving structured data. Everything needed to build a working ABBYY → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your ABBYY to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from ABBYY to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the ABBYY API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

ABBYY API at a glance

These values come from the ABBYY API documentation. Check them against the vendor's current reference before relying on them in production.

---

How do I authenticate with the ABBYY API?

ABBYY Vantage uses OAuth 2.0. Every API request must include an Authorization header with the format 'Bearer {your_access_token}'.

1. Get your credentials

To obtain API credentials, a Tenant Administrator must navigate to the ABBYY Vantage UI and follow these steps: 1. Log in to the Vantage tenant. 2. Navigate to 'Administration' > 'API clients' (or 'Configuration' > 'Public API Client'). 3. Click 'Add Client' (or 'Create API Client' for the first one). 4. In the resulting dialog, copy the generated 'Client ID' and 'Client Secret'. It is recommended to save these immediately, as the secret may not be retrievable later. Ensure the 'Allow client credentials flow' option is enabled for machine-to-machine integrations.

2. Add them to .dlt/secrets.toml

Copy
[sources.abbyy_source]
client_id = "REPLACE_ME"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What ABBYY data can I load into DuckDB?

These are the ABBYY endpoints dlt can load into DuckDB:

How do I load only new ABBYY records?

ABBYY exposes offset on api/publicapi/v1/catalogs/{catalogId}/records, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.

Copy
{"name": "catalog_records", "endpoint": {
    "path": "api/publicapi/v1/catalogs/{catalogId}/records",
    "incremental": {"cursor_path": "offset", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

---

What does the generated ABBYY pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading /auth2/connect/token and /vantage/api/v1/... (processing or reporting endpoints) from the ABBYY API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def abbyy_source(client_id=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://vantage-us.abbyy.com",
            "auth": {"type": "bearer", "token": client_id},
        },
        "resources": [
            {"name": "catalog_records", "endpoint": {"path": "api/publicapi/v1/catalogs/{catalogId}/records"}},
            {"name": "skills", "endpoint": {"path": "api/publicapi/v1/skills"}}
        ],
    }
    yield from rest_api_resources(config)


def load_abbyy_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="abbyy_pipeline",
        destination="duckdb",
        dataset_name="abbyy_data",
    )
    load_info = pipeline.run(abbyy_source())
    print(load_info)


if __name__ == "__main__":
    load_abbyy_to_duckdb()

Run it with python abbyy_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query ABBYY data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("abbyy_pipeline").dataset()
df = data.catalog_records.df()
print(df.head())

SQL:

Copy
SELECT * FROM abbyy_data.catalog_records LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

---

How do I deploy the ABBYY to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw ABBYY loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load ABBYY data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
