  note: >-
    Ajaib Coin Exchange uses an issued API key plus a per-request ECDSA-SHA256
    request signature. There is no OAuth 2.0 or OpenID Connect surface, so no
    scopes/ artifact is emitted.
provisioning:
  self_service: false
  process: >-
    The client generates an ECDSASHA256 keypair, then emails the public key to
    tech@ajaib.co.id. Ajaib returns an auto-generated API key bound to that
    public key and to the client's identity as an exchange client.
