Example Prompts

• "Look up IOTA group NA-005"
• "Search for islands named Shetland"
• "What IOTA groups are near Boise, Idaho?"
• "Show me all islands in EU-005"
• "What IOTA references map to DXCC 291?"
• "Give me IOTA programme statistics"

Data Source

Data comes from the official IOTA website JSON downloads:

• fulllist.json — complete group/subgroup/island hierarchy (~1.3 MB)
• dxcc_matches_one_iota.json — 1:1 DXCC-to-IOTA mapping (~3.5 KB)

Data is downloaded once and cached for 24 hours (IOTA refreshes daily at 00:00 UTC).
