Pastebin API Python API Docs | dltHub

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

Last updated:

Pastebin is a plain text storage service that provides an API for creating, listing, and managing text snippets called pastes. The REST API base URL is https://pastebin.com/api/ and Requests are authenticated via API keys sent in the POST body payload..

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 add "dlt[hub]" and start loading Pastebin API data in under 10 minutes.


What data can I load from Pastebin API?

Here are some of the endpoints you can load from Pastebin API:

ResourceEndpointMethodData selectorDescription
create_pasteapi/api_post.phpPOSTCreate a new paste (requires api_dev_key, optional api_user_key)
list_user_pastesapi/api_post.phpPOSTList pastes created by a user (requires api_dev_key, api_user_key)
login_userapi/api_post.phpPOSTLogin to get an api_user_key (requires api_dev_key)
get_raw_pasteraw/{paste_key}GETFetch raw paste content (public/unlisted)
list_recent_pastesapi_scraping.phpGETRequest most recent pastes (requires whitelisted IP)
get_paste_metadataapi_scrape_item_meta.phpGETFetch metadata of a specific paste (requires whitelisted IP)

How do I authenticate with the Pastebin API API?

Pastebin does not use standard Authorization headers; it requires an 'api_dev_key' (developer key) and an optional 'api_user_key' (user session token) to be sent as part of the POST body payload with 'application/x-www-form-urlencoded' content type. The user key is obtained via a separate login POST request using the username and password.

1. Get your credentials

To obtain your Pastebin API credentials, first sign up for a member account at https://pastebin.com/signup. Once logged in, navigate to the official API documentation page at https://pastebin.com/doc_api. Your 'Developer API Key' (api_dev_key) will be listed in the 'Your Unique Developer API Key' section on that page. To generate an 'API User Key' (api_user_key) for managing user-specific pastes, perform a POST request to the API login endpoint with your username and password, or use the online generator provided at https://pastebin.com/api/api_user_key.html.

2. Add them to .dlt/secrets.toml

[sources.pastebin_api_source] api_dev_key = "REPLACE_ME"

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 init uv add "dlt[hub]"

1. Install the dlt AI harness:

uv run dlthub 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:

uv run dlthub ai toolkit install rest-api-pipeline

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 Pastebin API 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:

uv run python pastebin_api_pipeline.py

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

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

Inspect your pipeline and data:

uv run dlthub 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 api_post.php and api_raw.php from the Pastebin API 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 pastebin_api_source(api_dev_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://pastebin.com/api/", "auth": {"type": "api_key", "api_key": api_dev_key, "name": "api_dev_key"}, }, "resources": [ {"name": "list_user_pastes", "endpoint": {"path": "api/api_post.php"}}, {"name": "list_recent_pastes", "endpoint": {"path": "api_scraping.php"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="pastebin_api_pipeline", destination="duckdb", dataset_name="pastebin_api_data", ) load_info = pipeline.run(pastebin_api_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("pastebin_api_pipeline").dataset() sessions_df = data.list_user_pastes.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM pastebin_api_data.list_user_pastes LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("pastebin_api_pipeline").dataset() data.list_user_pastes.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 Pastebin API 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.
