LegalizeBuild something new
The data is here. The API is open. These are ideas for what you could build on top of it.
Legislative change alerts
A service that notifies you when the laws you care about change. An employment lawyer gets a Telegram message when the Workers' Statute is reformed. An accountant gets an email when the VAT law changes. The exact diff of what changed, every time. The Legalize reforms API already has the data — it just needs to be packaged into notifications.
/api/v1/es/reforms
Every reform with date and affected articles
Exam prep with always up-to-date legislation
A study platform where exam candidates always see the current version of each law. When something changes, the platform marks exactly what is different since the last study session. Tests that regenerate automatically. The syllabus never goes stale because it feeds directly from the API.
/api/v1/es/laws
Full text of every law, always current
Auto-generated legislative flashcards
Pick any law, generate study cards from the real text. Export to Anki or Quizlet. When the law changes, the cards update and tell you what to review. Half a million exam candidates in Spain alone study legislation that can change under their feet.
/api/v1/es/laws
Full articles ready to parse into Q&A
AI legal assistant for citizens
A chatbot that answers legal questions citing the exact articles of the current law. 'Can my landlord raise rent more than 3%?' — answer with the article and the law. Legalize data is already structured to serve as a RAG knowledge base. Any law firm, city council, or advisory service could offer this to their users.
/api/v1/es/laws + /search
Structured text ready for embeddings
Tenant rights app
'My landlord wants to evict me.' The app shows the exact applicable law, updated to today. With the housing crisis across half of Europe, millions of people need to know their rights and the legislation keeps changing. It works in every country Legalize covers.
/api/v1/es/laws + /search
Housing law by country
Legal comparison across countries
How does data protection differ between Spain, France, and Germany? What about workers' rights? Rental law? The same query applied to 9 countries with the same data structure. For expats moving abroad, companies expanding, or researchers comparing legal systems.
/api/v1/es/search
Same query across multiple country endpoints
Weekly legislative changes podcast
Every Monday, a 10-minute audio summary of what changed in legislation during the week. Auto-generated from reform data. Lawyers and professionals listen on their commute. The content creates itself — you just need the voice.
/api/v1/es/reforms
Weekly reform data ready to summarize
Multi-country compliance dashboard
'We operate in Spain, France, and Germany.' A tool that shows which regulations apply to your industry in each country, and alerts you when something changes. Legalize's cross-border data with uniform structure makes possible what used to require consultants in each jurisdiction.
/api/v1/es/laws + /reforms
Cross-country regulatory monitoring
Law lookup at any past date
'What did this law say on March 15, 2023?' Legalize's version history has every state of every law. For lawyers handling old cases, insurers reviewing claims, or compliance audits that need to know which rule applied at a specific point in time. No one else has this as structured data.
/api/v1/es/laws
Full version history via git
Laws in plain language
Legislation rewritten in accessible language using AI. For people with cognitive disabilities, non-native speakers, or anyone who finds legal text impenetrable. Legalize's structured data is the source, AI does the translation into clear language. Massive social impact.
/api/v1/es/laws
Structured text ready for AI rewriting
Legal document checker
Upload a contract and the tool checks whether the law references it contains are still in force. 'This contract cites Article 23 of the Tenancy Act... that article was reformed 3 months ago.' For law firms, advisory services, and any business that signs contracts referencing legislation.
/api/v1/es/laws
Current text to verify references
Interactive guide to starting a business abroad
'I want to open a bakery.' The tool shows hygiene, labor, tax, and licensing regulations in each country. Compare where it's simplest. For entrepreneurs evaluating where to set up within the EU. Legalize covers 9 countries with the same data structure — the comparison is built in.
/api/v1/es/laws + /search
Regulations by sector across countries
Legal training data for AI
Structured, versioned datasets for fine-tuning legal language models. Laws as they were at any date, with diffs between versions. Legalize's git history is unique for this — no other source has temporal legal data in machine-readable format. Sell to AI companies building legal tools.
/api/v1/es/laws
Full version history in structured format
Regulatory risk score
Give any industry a risk score based on how often the laws that apply to it change. 'The fintech sector has a risk of 7.2/10 — its laws changed 12 times last year.' For investment funds, due diligence, and risk analysis. The reform history data is already there.
/api/v1/es/reforms
Reform frequency and patterns
No-code integration for legal data
Zapier and Make connectors for legislation. 'When law X changes → update my Notion → send Slack notification → update my compliance spreadsheet.' Nobody has this connector and the no-code builder market is massive. Legal data that plugs into any workflow.
/api/v1/es/reforms
Webhook-ready reform data
And many more.
These are just a starting point. The best idea is probably not on this list yet. With open data and an API, one person can build today what used to take an entire team. If you have an idea, build it.
