Security and privacy decision
Check ID
A single developer can build and run a secure structural SA ID validator and API in about a week; the product's durable value is mainly convenience, trust, and billing which are reproducible and not moat-level.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Accept an ID number, run structural checks (format, DOB encoding, citizenship byte, Luhn checksum), return decoded fields and validity via a REST API and web single-check UI.
What it still won’t have
- Brand reputation, existing user base (4,600+ monthly users and 815k historical validations)
- Polished SLA and sub-second response guarantees described on the site
- Built-in billing/plan management and team features (Professional/Business plans)
- Documentation, tutorials and ready-made integration snippets
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal SA ID structural validation service using Node.js (Express) and Postgres for usage counters, deployed on a single DigitalOcean droplet or equivalent. Core features in scope: (1) implement SA ID parsing and structural checks (date decoding, citizenship indicator, Luhn checksum) as a library; (2) REST API with bearer-token auth and endpoints GET /api/v1/validate/{id} and POST /api/v1/validate/bulk returning JSON with decoded fields and boolean valid; (3) single-page web UI for manual checks and a CSV bulk-upload page that returns a downloadable CSV of results; (4) lightweight billing/plan flagging to enforce a 1,000-calls/month quota and request counting (do not persist ID numbers); (5) TLS, basic rate-limiting, error handling, input validation, and unit tests for validation logic and API. Out of scope: Home Affairs or government lookups, biometric document scanning, and training ML models. Include automated tests, CI for deployments, and simple health and metrics endpoints.How we checked

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
