Use cases

These are situations where Registry Stack can be used to reach a specific outcome. Read the page that matches yours. Each one starts from a registry that already exists, walks through what you configure, and shows what a caller sends and gets back.

Ordered by how directly the case exercises the Stack’s highest-impact capabilities.

  • Expose a legacy registry as a protected API: the source is an Access database refreshed nightly from district offices, a pension authority needs an authoritative vital-status answer, and the registrar will not hand out a database credential.
  • Verify a status fact about a registered entity without sharing the full record: a procurement platform needs to confirm one thing about a supplier (are they actively registered?), and the existing API returns the beneficial-ownership chain and filing history with it. The same shape fits any status-coded registry.
  • Verify an eligibility or entitlement fact without sharing the full record: a school-feeding programme needs to confirm that a child’s household is enrolled in the cash-transfer programme run by a separate ministry, without receiving the household case file, income tier, or transfer history.
  • Publish registry metadata: three integration teams are asking the same questions (which fields, which districts, which access controls), and the ministry wants one canonical place to answer them before any data sharing agreement is signed.
  • Inspect a registry before integrating: the metadata URL has been published, three teams have been told to assess feasibility against it, and they need to know what is described, where the gaps are, and which route matches their information need.
