Case Study

Spain AI Kit

We don't only build for paying clients. Spain AI Kit is free and open-source — a set of tools that plug any AI assistant straight into Spain's public data: the laws, the statistics, the land registry, the weather. Built for the whole community, so every developer and solopreneur can build on it.

A builder freely sharing open-source AI tools across a glowing map of Spain

What we built around: The best AI infrastructure shouldn't be locked behind a paywall. Spain's public data — 12,000+ laws, decades of statistics, every property in the land registry, weather for 8,000+ towns — is all open, but buried in XML, SOAP endpoints, and Spanish-only docs no AI assistant can read. So we built the bridge, and we gave it away.

Not everything we build is for a client. Spain runs one of Europe's richest public-data infrastructures — national law dating back to 1661, thousands of statistical series, cadastral records for every property, weather for over 8,000 municipalities. It's all open data, but most of it is locked behind XML, SOAP endpoints, and Spanish-only documentation that AI assistants can't reach. So we built Spain AI Kit — a free, open-source set of connectors that plug any AI assistant straight into all of it — and released it for anyone to use. Because tools this useful shouldn't only reach the people who can pay for them.

Open source Free and MIT-licensed — anyone can use it, build on it, or contribute

Before

Spain's open data, locked away

  • 12,000+ laws trapped behind XML and SOAP endpoints
  • Statistics buried in idiosyncratic JSON-stat formats
  • Spanish-only documentation, nothing an AI assistant could read
  • Every developer re-solving the same plumbing from scratch
After

Now it is one line of config

  • Any AI assistant plugs straight into Spain's laws, stats, land registry, and weather
  • Ask a question in plain language, get an answer from official public data
  • Free and open-source — MIT-licensed, contributions welcome
  • Developers and solopreneurs build on it instead of rebuilding the plumbing
  • The whole community benefits — not only the people who can pay

What this looks like day-to-day

An autónomo can ask the law directly

A Spanish solopreneur can ask their AI assistant about a decree or a tax rule and get an answer grounded in the actual official gazette — no lawyer, no Spanish-only PDF.

A developer skips the plumbing

Instead of wrestling XML and SOAP for a week, they mount a connector and get straight to building their app.

The answers stay official

Every response comes from the source — the statistics office, the gazette, the land registry, the weather agency — not a scrape or a guess.

It is a public good, not a product

We built it, we open-sourced it, and it is free forever. The community can use it, extend it, or fork it.

Four connectors, one open standard

Spain AI Kit is a set of open-source connectors — each one a standalone bridge to a Spanish public-data source, usable on its own or together:

  1. Laws & legislation

    12,000+ consolidated Spanish laws — national and all 17 autonomous communities — plus the daily official gazette, at your AI's fingertips.

  2. National statistics

    70+ statistical operations — demographics, economy, employment, housing, tourism — through a plain-language interface.

  3. Land registry & addresses

    50 provinces and 8,000+ municipalities covered for property, address, and geocoding lookups.

  4. Weather & alerts

    Forecasts, UV index, fire risk, and beach conditions for the whole country.

  5. Built on the open standard

    Each piece speaks MCP — the open standard AI assistants use to reach outside tools — so it works with Claude, Cursor, and anything else that speaks it, and composes with other tools.
