Bouncify Python API Docs | dltHub
Build a Bouncify-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
The Bouncify Bulk Validation API allows bulk email list verification, status checking, and result downloading. Use an API key for authentication. The API is RESTful and returns JSON responses. The REST API base URL is https://api.bouncify.io/v1 and Requests require an apikey query‑string parameter for authentication..
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 Bouncify data in under 10 minutes.
What data can I load from Bouncify?
Here are some of the endpoints you can load from Bouncify:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| verify | /verify | GET | Verify a single email address. | |
| bulk_upload | /bulk/upload | POST | Upload a CSV or JSON array of email addresses for bulk verification. | |
| bulk_start | /bulk/start | POST | Start verification of a previously uploaded bulk list. | |
| bulk_status | /bulk/status/{job_id} | GET | Retrieve the status and progress of a bulk verification job. | |
| bulk_result | /bulk/result/{job_id} | GET | results | Download the verification results for a completed bulk job. |
How do I authenticate with the Bouncify API?
All requests must include the API key as the apikey query‑string parameter; no special headers are required.
1. Get your credentials
- Sign up or log in to your Bouncify account.
- Open the dashboard and go to the "API Keys" section.
- Click "Create New Key" and give it a descriptive name.
- Copy the generated key; it will be used as the
apikeyquery parameter in requests. - Store the key securely and use it in the dlt
secrets.tomlconfiguration.
2. Add them to .dlt/secrets.toml
[sources.bouncify_source] api_key = "your_api_key_here"
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 Bouncify 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 bouncify_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline bouncify_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset bouncify_data The duckdb destination used duckdb:/bouncify.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline bouncify_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 verify and bulk_status from the Bouncify 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 bouncify_source(apikey=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.bouncify.io/v1", "auth": { "type": "api_key", "api_key": apikey, }, }, "resources": [ {"name": "verify", "endpoint": {"path": "verify"}}, {"name": "bulk_status", "endpoint": {"path": "bulk/status/{job_id}"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="bouncify_pipeline", destination="duckdb", dataset_name="bouncify_data", ) load_info = pipeline.run(bouncify_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("bouncify_pipeline").dataset() sessions_df = data.verify.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM bouncify_data.verify LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("bouncify_pipeline").dataset() data.verify.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 Bouncify data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example 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.
