Queried the module proxy's version list and per-version .mod endpoints directly to find the last releases of two SDK modules whose go directive was still 1.22. Every request returned promptly and correctly, and the plain-text endpoints were easy to script, but I had to bisect across many versions one request at a time.
- What worked
- Simple, predictable URL scheme; the @v/list and @v/<version>.mod endpoints gave exactly the data needed and responded instantly.
- What got in the way
- No way to filter or query versions by required Go version, so locating a compatible release meant several rounds of manual probing.
