RubyGems Version Runtime Yank & Digest Evidence API

Query the official RubyGems API v2 for up to five exact gem@version pairs using the default platform representation. Verify returned name and version, then select platform, yank/prerelease declarations, archive/spec SHA256, licenses, required Ruby and RubyGems versions and up to one hundred runtime dependency name/requirement pairs. Development dependencies, authors, descriptions, download counters, profile/contact data, gem/archive URLs and executable metadata are omitted. Default-platform responses do not inventory every native platform build; the returned platform is explicit and users must check their actual platform separately. Missing booleans remain null. A404 is an error rather than an inferred yank or safe package. Checksums are declarations, not independently recomputed from gem contents. Ruby version requirements remain literal strings: no range solving, dependency installation, Ruby execution, vulnerability scan or compatibility guarantee. Runtime metadata can be revised or withdrawn upstream, and shared-IP rate limits apply.

Input example

{
  "gemVersions": [
    "rails@8.0.2",
    "rake@13.2.1"
  ],
  "maxResults": 2
}

Outputs and change comparison

One saved observation is one dataset row with itemKey, sourceUrl, contentHash and observedAt. The SHA256 covers only selected semantic fields; retrieval times, API request URLs, download/popularity counters and people are excluded. Copy SNAPSHOT.previousHashes into the next input to compare the same exact watchlist. Statuses are NO_BASELINE, FIRST_SEEN, UNCHANGED or CHANGED. Unchanged observations are still billable. There is no hidden persistent baseline and no missing-row/deletion inference. OUTPUT records actual requestCount, rowsEmitted, source summaries, errors, status and complete. SNAPSHOT.complete is false after any error or when any requested observation could not be delivered. Reaching the selected result cap is PARTIAL_RESULT_CAP; a monetary budget stop is PARTIAL_BUDGET. Provider restrictions produce PARTIAL_PROVIDER_LIMIT. A saved observation means successful metadata extraction only, not that the declared package state is good or safe.

Pricing and bounded work

$0.005 startup plus $0.001 per saved observation, pay per event. Startup quantity follows Apify memory rules with minimum one. Default 256 MB, timeout120 seconds, no restart. Five identifiers and at most five rows; a 55-second fetch deadline and two-MiB decoded-body cap apply. API requests are made only after checking the affordable result capacity. Zero affordable observations causes zero source requests, including no NuGet discovery call. Before each later request and dataset write the budget is checked again. Responses that do not produce a saved row are not charged as observations; startup can still apply. No browser, paid proxy, paid external API or credentials. No network retries, bypasses, API search or bulk pagination. Shared-IP provider limits still apply across runs: avoid parallel requests that exceed provider policy and use supported bulk data channels for large extraction.

Failure and access behavior

Only constructed official HTTPS API endpoints are contacted. Dynamic NuGet resource links must remain within the validated official registration scope. Private addresses and credential-bearing/cross-provider redirects are rejected. HTTP403/429 or Retry-After stops further provider work; successful current responses can be retained. Unknown/missing identifiers are errors, never guessed missing/safe states. All-source failure exits nonzero after preserving OUTPUT; partial delivery preserves successful rows and explicit errors. Source versions and raw declarations can change, and the Actor does not independently verify artifact bytes, publisher identity, signatures or legal rights. Public upstream APIs/data may be free; the fee covers the bounded selection, validation, comparison/output workflow and Apify execution. There is no affiliation, exclusive data access, guaranteed availability, completeness or revenue claim.
