The Curriculum API

Your AI is guessing the curriculum. Stop it.

Every model has read about the Lehrplan. None has read it. currikon has: 234,161 competencies from 21 curricula, each traceable to its paragraph.

A claim is a link, or it is a claim.

Plain JSON with a stable code, a grade band, a domain, and on every record the paragraph it came from. A test fails the build without it.

The problem

21 curriculum systems, 1,750 curricula, and every team parses them again.

The model's memory

Invents a code that looks right. No paragraph to show a teacher.

Your own parser

Someone parses Bavaria on a Tuesday. Bavaria changes. They parse it again.

currikon

Parsed once, with a receipt. Stable codes, a grade band, a source on every record. You get JSON.

For agents

Ask currikon, not the model's memory.

A language model will happily invent a competency code that looks right. Give it a tool instead. Free text goes in, ranked competencies come out with their sources attached, and your product cites the Lehrplan rather than paraphrasing it.

POST /v1/align

Alignment endpoint

Send a learning objective, a worksheet title or a paragraph of text. Get back the matching competencies, scored, with jurisdiction, grade band and source paragraph.

npx @currikon/mcp

MCP server

The same corpus as a tool for Claude, Claude Code and any agent that speaks MCP. Search, look up, find equivalents and align, from inside the assistant.

meinUnterricht's assistant is built on it

Teachers ask for material by curriculum or textbook; the assistant asks currikon and answers with the competency, not a guess. Launching this autumn.

Quickstart

FAQ

Questions people actually ask.

Do I need a key for every endpoint?

Yes. Production requires a key on all endpoints. The homepage demo runs through a rate-limited public route.

What counts as a request?

One call to any endpoint. Align and chat consume credits from a credit pack in addition.

Can I export?

CASE v1.1 CFPackages per framework, and JSON everywhere. Your data, no lock-in.

Where is it hosted?

In Germany. Records never leave the EU.

How fresh is the data?

Every record carries the source document and its valid-from date; the corpus snapshot date is in the footer. Re-extraction is recipe-driven and count-pinned in CI, so a changed Lehrplan is a visible diff, not a silent drift.

How do you stop the model from inventing a competency?

The API does not generate competencies; it retrieves records that exist, each with its source paragraph. A test in the build refuses any record without provenance.
