NuGet

Mode: 🌐 Public · Domain: api.nuget.org

Search the NuGet package index by keyword and fetch full version history for a package id. NuGet is the canonical .NET package registry; both endpoints are public V3 JSON.

Commands

Command	Description
opencli nuget search <query>	Search NuGet packages by keyword
opencli nuget package <id>	Full NuGet package version history (catalog entries)

Usage Examples

# Keyword search
opencli nuget search newtonsoft
opencli nuget search "asp.net core" --limit 10
opencli nuget search serilog --prerelease=true

# Full version history (id round-trips from search)
opencli nuget package Newtonsoft.Json
opencli nuget package Serilog
opencli nuget package Microsoft.Extensions.Logging

Output Columns

Command	Columns
search	rank, id, version, title, description, authors, tags, totalDownloads, verified, projectUrl, url

Notes

• package returns the full version history, newest-first (sorted by published desc, ties broken by version string desc). Each row is one published release. NuGet's CDN paginates internally; the adapter walks pages so even 100+ version histories come back in one call.
• listed flag: when false, the version was unlisted by the publisher (still installable by exact pin, but hidden from search). null when NuGet didn't include the field (rare, very old packages).
• verified (search only): NuGet's "verified publisher" badge — packages signed by a verified org. Useful for filtering hostile typo-squats.
• totalDownloads is a single global counter; it does NOT split per-version. For per-version downloads NuGet exposes a different endpoint we don't surface here.
• tags / authors are comma-joined; raw shape is space-separated tags + JSON author array, normalised to consistent comma joins.
• No API key required. NuGet's V3 service index is public; no rate limit doc but bursts → CommandExecutionError.
• Errors. Bad id / bad limit / empty query → ArgumentError; unknown package (HTTP 404) → EmptyResultError; transport / 429 / non-200 → CommandExecutionError.
