# WWW::Bund - New APIs Implementation Summary

## Overview

Successfully implemented **10 new public APIs** with **58 endpoints** across **7 languages**.

**Status:** ✅ All code written, NOT committed (as requested)

## What Was Implemented

### 1. Code Infrastructure (10 CLI Command Classes)

All located in `lib/WWW/Bund/CLI/Cmd/`:

- **Destatis.pm** - Federal Statistical Office (4 endpoints)
- **Luftqualitaet.pm** - Air Quality (13 endpoints)
- **Abfallnavi.pm** - Waste Management (10 endpoints)
- **Ddb.pm** - German Digital Library (3 endpoints)
- **Deutschlandatlas.pm** - Germany Atlas (1 endpoint)
- **Handelsregister.pm** - Commercial Register (1 endpoint)
- **Marktstammdaten.pm** - Market Master Data (8 endpoints)
- **Mudab.pm** - Marine Environmental Database (11 endpoints)
- **Pflanzenschutzmittelzulassung.pm** - Plant Protection Products (6 endpoints)
- **Regionalatlas.pm** - Regional Atlas (1 endpoint)

Each class follows the `Role::APICommand` pattern (~10 LOC).

### 2. Endpoint Definitions

Added **58 new endpoints** to `share/endpoints.yml`:

## API Coverage Summary

### Total APIs in Registry: 31
- **Implemented:** 26 APIs (16 previous + 10 new)
- **Remaining Public (no auth):** 0
- **Requires Authentication:** 5 (ausbildungssuche, bewerberboerse, jobsuche, lebensmittelwarnung, dip_bundestag)

**Public API coverage: 100% complete! 🎉**

## Next Steps (For Review)

1. **Review implementation** - Check code quality and completeness
2. **Live API testing** - Test all 58 new endpoints with real data
3. **Update documentation**:
   - Update `CLAUDE.md` API table (add 10 new APIs)
   - Update `README.md` with new APIs and examples
   - Update `Changes` file for release notes
4. **Commit** - Create commit with comprehensive message
5. **Release** - Version bump and release to CPAN

## Statistics

- **Lines of Code:** ~600 (10 CLI classes + endpoint definitions)
- **Template Files:** 406 new files
- **Languages Supported:** 7 (de, en, fr, es, it, nl, pl)
- **Total Endpoints:** 135 (78 → 135, +73%)
- **API Coverage:** 26/26 public APIs (100%)
- **Test Coverage:** 52 modules loading successfully

## Notes

- ✅ All templates use native Perl `open()` with `:utf8` for proper UTF-8 handling
- ✅ All templates follow WWW::Bund conventions (type, columns, empty, extract)
- ✅ All empty messages appropriately translated for each language
- ✅ All CLI command classes follow `Role::APICommand` pattern
- ✅ All endpoint definitions include proper cache TTLs
- ✅ Special handling for POST methods (mudab API)
- ✅ Authentication parameters included where required (destatis)
- ⚠️ Live API testing still needed
- ⚠️ NOT committed yet (as requested)
