Data Notes

• Years covered: 1990 through current year (2026 as of latest data)
• Billionaires per year: Typically top 10, some years have more
• Net worth parsing: The net_worth_billions field provides a numeric value extracted from the display string
• Wikipedia links: Extracted from the Name column when available
• Historical changes: Column headers may vary slightly across years (e.g., "Source(s) of wealth" vs "Primary source(s) of wealth")

Error Handling

All functions return an error field on failure:

{
  "error": "Year 1985 not found. Available years: ['1990', '1991', ...]"
}

Search returns found: false for no matches:

{
  "query": "nonexistent person",
  "found": false,
  "message": "No billionaires found matching \"nonexistent person\""
}

Implementation Notes

• Uses direct HTTP requests with proper User-Agent headers
• Parses HTML with BeautifulSoup
• No browser automation required
• Respects Wikipedia's rate limiting guidelines
