Lemonway Python API Docs | dltHub

Build a Lemonway-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.

Last updated:

Lemonway is an API that provides a compliant and conversion-friendly online onboarding flow for individuals and legal entities, handling data capture, KYC documents, identity checks, and live status. The REST API base URL is https://api.lemonway.com and Authentication details are not available in the provided documentation..

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv pip install "dlt[workspace]" and start loading Lemonway data in under 10 minutes.


What data can I load from Lemonway?

Here are some of the endpoints you can load from Lemonway:

ResourceEndpointMethodData selectorDescription
account_document/accountdocument/{id}/{type}GETGet Account Document by ID and Type
account_overview/accountoverviewGETRetrieve Account Overview (Profile, Wallets & Onboarding Status)
accounts/accountsGETList Accounts (Individuals & Legal Entities)
accounts_retrieve/accounts_retrievePOSTLets your system to get detailed payment account information including: payment account balance, account type, if the account is blocked, and account email ...
onboardings_createonboarding/onboardings/createonboardingPOSTRetrieves a continuation (resume) URL for a previously-started, in-progress onboarding session.
accounts_find/accounts/findGETFetch details for a single account by its unique ID.

How do I authenticate with the Lemonway API?

Authentication mechanism and required headers are not available in the provided documentation.

1. Get your credentials

Instructions for obtaining API credentials are not available in the provided documentation.

2. Add them to .dlt/secrets.toml

[sources.lemonway_online_onboarding_source] Authentication details are not available, so a `secrets.toml` example cannot be provided.

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.


How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

uv venv && source .venv/bin/activate uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

dlt ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

dlt ai toolkit rest-api-pipeline install

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Lemonway API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

python lemonway_online_onboarding_pipeline.py

If everything is configured correctly, you'll see output like this:

Pipeline lemonway_online_onboarding_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset lemonway_online_onboarding_data The duckdb destination used duckdb:/lemonway_online_onboarding.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

dlt pipeline lemonway_online_onboarding_pipeline show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.


Python pipeline example

This example loads accounts and accounts_retrieve from the Lemonway API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def lemonway_online_onboarding_source(Authentication parameter name is not available in the provided documentation.=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.lemonway.com", "auth": { "type": "Authentication type is not available in the provided documentation.", "Authentication token key is not available in the provided documentation.": Authentication parameter name is not available in the provided documentation., }, }, "resources": [ {"name": "accounts", "endpoint": {"path": "accounts"}}, {"name": "accounts_retrieve", "endpoint": {"path": "accounts_retrieve"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="lemonway_online_onboarding_pipeline", destination="duckdb", dataset_name="lemonway_online_onboarding_data", ) load_info = pipeline.run(lemonway_online_onboarding_source()) print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.


How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

import dlt data = dlt.pipeline("lemonway_online_onboarding_pipeline").dataset() sessions_df = data.accounts_retrieve.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM lemonway_online_onboarding_data.accounts_retrieve LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("lemonway_online_onboarding_pipeline").dataset() data.accounts_retrieve.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.


What destinations can I load Lemonway data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

DestinationExample value
DuckDB (local, default)"duckdb"
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.


Troubleshooting

No specific troubleshooting information regarding API-specific errors (e.g., auth failures, rate limits, pagination quirks) was found in the provided documentation.

Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
