Set LEGALIZE_API_KEY in your environment. Every SDK reads it automatically — no argument needed.

from legalize import Legalize client = Legalize() # Search the Spanish civil code, auto-paginated for law in client.laws.search_iter("es", q="propiedad intelectual"): print(law.id, law.title)

import { Legalize } from "@legalize-dev/sdk"; const client = new Legalize(); // Search the Spanish civil code, auto-paginated for await (const law of client.laws.searchIter("es", "propiedad intelectual")) { console.log(law.id, law.title); }

client, _ := legalize.New() defer client.Close() iter := client.Laws().SearchIter(ctx, "es", "propiedad intelectual", nil) for { law, ok, err := iter.Next(ctx) if err != nil || !ok { break } fmt.Println(law.ID, law.Title) }

Why this API is different

Time-travel

Every law has a git history

Each reform is a commit, and you can fetch the text of any law at any past revision with one call. No other legal API ships this.

Structured

Markdown + typed metadata

Body as clean Markdown, frontmatter with jurisdiction, status, dates, reform IDs. Drop into a RAG pipeline without scraping HTML.

Cross-border

One API, 32 countries

ES, FR, DE, AT, SE, LV, LT, PT, UY, CL, and counting. Same schema, same Bearer token. No per-country onboarding.

Change feed

Know the day a law changes

Push or pull, same events either way. Register a webhook and each change lands on your endpoint, HMAC-signed and retried, with a delivery log you can query — or poll /changes?since= and host nothing. Both follow the daily sync.
