**Stable release:** `v1.0.0`
The SA Public API Observatory is a public, machine-readable catalogue and independent observability system for South African public-data infrastructure and the wider ZA API ecosystem.
It answers three separate questions:
1. **What public-data infrastructure exists?**
2. **Is it actually working?**
3. **Is the data being served still current?**
Publication, transport availability, and data freshness are deliberately treated as different facts.
An endpoint returning HTTP `200` does **not** necessarily mean its data is current.

## Why this exists
Public APIs, statistical systems, GIS services, and open-data portals are increasingly important infrastructure.
But discovering that an API exists is not enough.
A useful public-data system also needs to answer:
- Is the endpoint reachable?
- Is the payload structurally valid?
- How reliable has it been?
- Is authentication unexpectedly required?
- Is it rate-limited?
- Is the published data fresh?
- Has its interface or schema changed?
- Is there an active incident?
- When did it recover?
- What evidence supports the current status?
The Observatory records those observations independently rather than simply repeating publisher claims.
**Unknown information remains unknown. Historical observations are never fabricated.**

## Who it is for
The Observatory is intended for:
- software developers integrating South African public data
- data journalists and investigative researchers
- academics and policy researchers
- civic-tech projects
- government and public-sector technical teams
- businesses that depend on public information
- automated systems and AI agents that need machine-readable trust signals
