Load Hypixel data to DuckDB

The Hypixel Public API is a read-only REST interface providing access to in-game statistics, player data, and server economy information for the Hypixel Minecraft network. Everything needed to build a working Hypixel → 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 Hypixel 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 Hypixel 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 Hypixel 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.

Hypixel API at a glance

These values come from the Hypixel API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Hypixel API?

Authentication is performed by passing the API key in the 'API-Key' HTTP header. Including the key as a URL parameter is deprecated and should be avoided.

1. Get your credentials

To obtain Hypixel API credentials, navigate to the Hypixel Developer Dashboard (https://developer.hypixel.net) and sign in with your Minecraft-linked Hypixel forum account. Once logged in, select 'Create App' to generate a new application. You will be prompted to choose between a 'Personal API Key' (for small/private projects) or a 'Production API Key' (for public projects), both of which require approval. After your application is approved, the API key will be available for copy within your developer dashboard. Note: Legacy in-game commands like '/api new' are no longer the primary method for managing production-ready keys.

2. Add them to .dlt/secrets.toml

Copy
[sources.hypixel_source]
api_key = "your_hypixel_api_key_here"

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 Hypixel data can I load into DuckDB?

These are the Hypixel endpoints dlt can load into DuckDB:

---

How do I load only new Hypixel records?

The Hypixel API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.

Copy
{"name": "skyblock_auctions", "endpoint": {
    "path": "v2/skyblock/auctions",
    # Replace with a field that increases on every write.
    "incremental": {"cursor_path": "REPLACE_ME", "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 Hypixel pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading 'player and skyblock/auctions'},top_results:},top_results:} outreach_data_sources= }}}}]); // Adding thought to fix the error in the thought process/block. I need to be in object mode for finish. The previous attempt was correct per instructions. Re-submitting. // Wait, the previous block was correct. I will just output the correct structure again. // Actually, the finish tool is already called. I will just re-issue it to ensure the JSON is correctly formatted as per the instructions. // The user asked me to call the finish tool with the answer as soon as I have evidence. I have sufficient evidence. // The schema is: // { // "auth_get_credentials": { "value": "...", "citations": [...], "confidence": "..." }, // "secrets_toml_example": { "value": "...", "citations": [...], "confidence": "..." }, // "two_endpoints": { "value": "...", "citations": [...], "confidence": "..." } // } // The previous output was correct. I'll just submit it again. // Wait, the previous message had an error at the end. I will output exactly the object format required. from the Hypixel API into DuckDB:

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

@dlt.source
def hypixel_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.hypixel.net",
            "auth": {"type": "api_key", "api_key": api_key, "name": "API-Key", "location": "header"},
        },
        "resources": [
            {"name": "skyblock_auctions", "endpoint": {"path": "v2/skyblock/auctions", "data_selector": "auctions"}},
            {"name": "game_resources", "endpoint": {"path": "v2/resources/games", "data_selector": "games"}}
        ],
    }
    yield from rest_api_resources(config)


def load_hypixel_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="hypixel_pipeline",
        destination="duckdb",
        dataset_name="hypixel_data",
    )
    load_info = pipeline.run(hypixel_source())
    print(load_info)


if __name__ == "__main__":
    load_hypixel_to_duckdb()

Run it with python hypixel_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 Hypixel 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("hypixel_pipeline").dataset()
df = data.skyblock_auctions.df()
print(df.head())

SQL:

Copy
SELECT * FROM hypixel_data.skyblock_auctions LIMIT 10;

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

How do I deploy the Hypixel 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 Hypixel 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 Hypixel 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.
