Elementus

aid: elementus
name: Elementus
description: Elementus is a New York blockchain intelligence company founded in 2017 that attributes on-chain addresses to
  real-world entities across multiple chains, and sells that attribution graph to compliance, investigations and market-intelligence
  teams. Its public API surface is the Attribution API, a key-authenticated REST service at attribution-api.elementus.io that
  resolves batches of blockchain addresses to a beneficial owner, custodian, entity name and OFAC/SDN sanction status. As
  of the 2026-08-12 probe every Elementus web host — the marketing site, the app and the API — is unresolvable in DNS, so
  the developer surface documented here is reconstructed from the company's own public GitHub organization rather than from
  a live site.

- name: Elementus Attribution API
  description: REST API that resolves a batch of blockchain addresses to attribution data — beneficial owner, custodian, entity
    name, OFAC sanction flag and SDN name. Authenticated with an X-API-Key header. The operation surface documented in Elementus'
    own public API example client is POST /address-attributions and GET /health, with a Swagger UI advertised at /swagger-ui.
    The host does not currently resolve.

x-coverage:
  state: none
  reason: defunct
  detail: Elementus' entire web surface has been withdrawn from DNS — the apex publishes no address record, www.elementus.io
    is NXDOMAIN, and both attribution-api.elementus.io and app.elementus.io are dangling CNAMEs to an AWS load balancer and
    a CloudFront distribution that no longer exist — while the zone itself stays live on Cloudflare and still routes mail
    to Google Workspace, so the company has parked its public presence rather than released the domain.
