# Leif

> Leif (Leif Technologies, Inc.) was a New York City education-finance technology company,
> founded in 2017, that built an end-to-end platform for designing, originating, servicing and
> financing outcomes-aligned tuition products — Income Share Agreements, contingent payment
> plans, tuition installment plans and upfront payment — for schools and bootcamps.

## Status

- **This company has no public API.** Leif never operated a developer program. The last
  archived capture of its marketing site (2025-11-09) has no developer portal, API reference,
  documentation, SDK or OpenAPI link anywhere in its navigation. The only API surface ever
  visible was the private JSON API behind its own student and school applications
  (`leif.org/api/students`, `/api/products/{id}`, `/api/commit/provider/{id}`), which was
  never documented for third parties.
- **The public surface is dark as of 2026-08-25.** `leif.org` and `www.leif.org` fail the TLS
  handshake at their Webflow edge; `app.leif.org` returns HTTP 504 on every path;
  `staging.leif.org` returns 503; `partners.leif.org` returns a Webflow 404 for every path;
  the `leiforg.zendesk.com` help center returns 404; and `status.leif.org` does not resolve.
- `api.leif.org` and `sandbox.leif.org` are still-provisioned AWS API Gateway hosts (valid
  `*.leif.org` certificate issued 2026-07-12) but answer
  `{"message":"Missing Authentication Token"}` — the API Gateway default for an unmatched
  route — on every path probed, including `/openapi.json`, `/swagger.json`, `/graphql` and
  every `/.well-known/*` path.

## What Leif did

- Income Share Agreement design, origination and program management for schools
- Contingent payment plans, tuition installment plans and upfront tuition payment

- No A2A agent card, MCP server, `llms.txt`, Postman collection or first-party SDK exists.
