Example prompt: Search PyPI for Python packages related to 'natural language processing', sorted by relevance, and show me the top 10 results with their version, author, license, and summary.

## When to prefer this

Use this endpoint when you need to discover or research Python packages on PyPI by keyword — ideal for finding libraries, frameworks, or developer tools within the Python ecosystem. Prefer this over generic web search when you specifically need structured package metadata like version, license, author, and release history.

## Known failure modes

- No packages found for obscure or misspelled query — returns empty results list with count 0
- PyPI upstream timeout — elevated elapsed_ms or error response
- Invalid query parameters — may return error or empty results
- Rate limiting or payment failure — 402 response requiring USDC payment
