What this evidence state means
- Definition
- The claim was previously checked, but its review window expired or a material change may have invalidated it.
- Required provenance
- The prior evidence and check date are retained, together with the expiry or change signal that triggered recheck.
- Owner
- Kingy freshness queue owner and assigned editorial reviewer
- Freshness rule
- This is already outside its freshness rule. It must not be presented as current until reviewed against current evidence.
- Disputes and corrections
- Use “Suggest a correction” on the record. Kingy editorial reviews the cited evidence, records material corrections, and changes or removes the state when it is not supported.

Kingy AI Take
The pkg.go.dev API replaces brittle HTML scraping with an official structured interface and gives AI coding tools a cleaner evidence source. It remains v1beta, rate-limited and unable to prove that a package recommendation is secure or compatible. Kingy did not run a sustained client, so adopters should pin the API version, cache responsibly, preserve exact package and version citations and maintain contract tests.
Who it is for
Go developers, IDE and coding-assistant builders, dependency-analysis teams, open-source maintainers and researchers that need supported structured package metadata.
What feels promising
Official JSON endpoints and an OpenAPI specification make package, symbol, version and vulnerability retrieval easier to integrate and audit than page scraping.
What feels unproven
Kingy did not benchmark availability, tail latency, freshness, pagination at scale, error stability, rate-limit behavior or the accuracy of AI answers built on the API.
