Sancho Fetch

Ask your AI for public data. Get real files on your computer.

The fastest way in: tell your AI

Open your AI's code mode -- Claude desktop app -> Code tab, or ChatGPT desktop app -> Codex -- pick any folder, and paste this:

Install Sancho Fetch from PyPI (uv tool install sancho-fetch) and set it

up on this computer. If uv isn't installed, tell me, then install it

first. When you're done, tell me whether the install succeeded. Then

explain in plain English, no jargon: what the .env file is, how to use it,

where it is on my computer, and open it for me so I can paste API keys

straight into it. Give me a few examples of data sources that need a free

API key and a few examples of sources that don't need a key. Tell me where

my downloaded data gets saved, and how I update Sancho later. Then run a

short example data fetch using the World Bank so I can see where the data

was saved. Finally tell me a few natural language examples I can tell you

to fetch data so I can get a feel for how to use sancho-fetch and remind

me that 1) I can use it anywhere as long as I'm in a LLM Desktop app's

Code tab (e.g. ChatGPT Desktop or Claude Desktop), and 2) that I can ask

AI to add new data sources by itself since sancho-fetch is built in a way

that it's easily extensible (aka you can add more to it and the AI will do

the heavy lifting and connect the new data source).

That's the whole install.

You do not need to download or clone this repository. The two commands the AI runs are:

uv tool install sancho-fetch

sancho setup

Install once, use everywhere. Sancho installs once on your computer and connects to the AI apps it finds (Claude Desktop, ChatGPT/Codex, VS Code, Cursor). At the end of setup it tells you plainly which apps are ready and which just need a restart or a click.

To use Sancho, just ask for data and mention "sancho" in plain English, or type `/sancho` in Claude Code to feel cool.

What it does

  • In your AI's Code mode you ask: *"get county-level asthma rates for Ohio."* You can be working in any folder -- Sancho always knows where its home folder is.
  • Your AI uses Sancho to pull from 120+ public sources (Census, World Bank, FDA, USGS, FEMA, ...) and hands you a file that opens in Excel.
  • Everything is saved on your computer.

Before you begin

The normal prerequisite is uv. uv installs Sancho in isolation and can obtain a compatible Python without replacing your computer's system Python. First setup needs an internet connection. API keys are not required for installation or the World Bank example; provider-specific keys can be added later.

Get started (about 2 minutes)

Install straight from PyPI.

1. Open your AI's code mode.

  • Claude: Claude desktop app -> Code tab -> new session -> pick any folder where you want your data to live.
  • ChatGPT: ChatGPT desktop app -> Codex -> open that folder.

2. Paste the install request from the top of this page.

The AI installs everything, shows you your first data file, and walks you through where everything lives.

3. Restart the apps Sancho asks you to restart. Setup ends with a short report; if an app needs a restart or one extra click, it says so in plain words.

NOTE: Before using, make sure to add API keys for any sources you want to use.

Many sources need no key (World Bank, USGS, FEMA, openFDA, ...). Your AI will tell you when an API key is needed. You can either:

  1. Open the .env file in the sancho-workspace folder and paste your key there; or
  2. Ask your AI to open the keys file for you (sancho env open). Paste the key into the opened file, **don't paste your key

into the chat**.

Setup normally creates .env from .env.example. If .env is missing, sancho env open creates and opens it. To do this manually, copy .env.example in the same folder, keep the original template, and name the copy .env.

Both files may be hidden:

  • macOS Finder: press Cmd+Shift+. (Command + Shift + period).
  • Windows File Explorer: select View -> Show -> Hidden items.

@Developers, fyi Sancho is designed to read key names only, not values.

Prefer the GitHub repository, or installing without an AI app?

For contributing, custom module development, or offline installs, work from the repository folder instead. Install GitHub Desktop (free), then on this repository's page click Code -> Open with GitHub Desktop -> Clone.

Note: Avoid placing the Github folder in a folder that is within iCloud/OneDrive (e.g. Documents folder in iCloud). This causes issues with file syncing and speed.

Then double-click installers/Install Sancho.command (macOS) or installers/Install Sancho.bat (Windows); on Linux run bash installers/setup.sh.

  • macOS blocks the first open (the installer is not notarized): System Settings -> Privacy & Security -> scroll to the blocked-file message -> Open Anyway -> open it again.
  • Windows: at "Windows protected your PC", click More info -> Run anyway.

Everyday use

  • In Claude Code / Codex, just ask for data. In Claude Code you can also type `/sancho` and `/sancho-update` directly.

After installation, use a Code session. Sancho is installed

computer-wide, so you do not need to add the sancho-fetch folder in future

sessions. In Claude Desktop, select the Code tab. In **Codex, start a

Code chat**. Regular chats cannot access your local Sancho installation.

  • There are system instructions to make Sancho return non-technical details of each data pull, so if you want these technical details returned, tell your AI:

*"turn on Sancho developer mode."*

  • Something off? Ask your AI to run sancho ready -- it checks your setup and reports what's wrong, without changing your setup. To actually fix problems, ask your AI to run sancho doctor --fix.

Where your files land

your folder/

sancho-downloads/ # <-- files you have downloaded via chatting with AI sancho-workspace/ source/ # managed data modules custom/ # your own modules -- never overwritten when updating Sancho playbooks/ # your repeatable workflows fetched-data/ # faithful archive of every fetch (don't edit - this is a cache so we don't have to use API calls unnecessarily) analysis-data/ # your derived work outputs/ # reports, dashboards, exports logs/ # what Sancho did, when, and why update-backups/ # snapshots before every update .env # your API keys (never logged, never printed)

Every fetch writes a working file you open -- into sancho-downloads/ in the folder that you're working in -- and a faithful archive/cache copy in sancho-workspace/fetched-data/ so repeat requests reuse cached data.

Tables arrive as Excel .xlsx with codes like 01003 kept intact; maps stay GeoJSON/KML; nothing is converted in a way that loses information. Filenames start with the date: 2026-06-08_194211_alabama-population.xlsx.

Add your own data sources

Tell your AI:

Create a Sancho module for [that API / that agency's data / this file I

receive every month].

It's built under custom/, works like the built-in sources, and Sancho updates never overwrite the folder.

A good example of this is, Sancho fetches from Washington DC's and New York City's open data portals, which use a common API/open data portal format. The AI can be asked to create a module for other cities and will intelligently check on its own whether the new city uses the same format or not, and if it does, will reuse the same module code format (and otherwise, create a new one). You'd be surprised at how many cities use the same format so give it a try if you're working in a geographic regional level that is not already covered by Sancho's built-in modules.

Updates

Just ask your AI:

Update Sancho.

The AI upgrades the sancho command from PyPI (uv tool upgrade sancho-fetch) and then migrates your workspace safely, with a backup and a rollback command.

Working from the GitHub repository instead? In GitHub Desktop: Fetch origin -> Pull origin, then tell your AI *"update Sancho."*

When updating, your own files (custom/, playbooks/, fetched-data/, .env, ...) are never touched.

If you want Sancho to stop mentioning new versions in chats (which it will do once every 2 weeks), simply set SANCHO_UPDATE_NUDGE=false in .env to turn it off.

Uninstalling

Same as installing: paste one request to your AI in a Code session:

Uninstall Sancho Fetch from this computer: run sancho uninstall, then

uv tool uninstall sancho-fetch. Keep my sancho-workspace and

sancho-downloads folders -- that is my data and my API keys. Tell me when

it's done and what was removed.

(Those two commands are the whole uninstall if you'd rather run them yourself.)

Sancho only removes what it installed: its skills and its entries in your AI apps. Anything you edited or created yourself is left alone and reported.

Your sancho-workspace/ folder (fetched data, custom modules, .env keys) and your sancho-downloads/ files are always kept. Deleting data is a separate, deliberate step that asks for confirmation first -- ask your AI, or run sancho uninstall --help to see how.

Privacy Policy

Sancho runs on your computer and keeps your data there. Fetches go directly from your machine to the public data provider you chose; API keys are read from your local .env and sent only to that provider. Sancho has no telemetry. Full details: docs/PRIVACY.md.

Hosting your own version of Sancho

While Sancho is designed to run on your own computer, you can also host it on a server so that users can access it via web rather than needing Claude/Codex desktop apps.

The idea with hosting was primarily to support organizations hosting hands-on workshops for users who may not have the technical skills to install Sancho on their own computers.
