How this service works
Return auditable npm package registration and publication chronology evidence.
Output
The endpoint returns a structured chronology of the npm package's registration and publication events, including timestamps for initial registration and subsequent version releases, formatted as auditable evidence suitable for compliance or security review.
Example use cases
Supply chain security audit
“I need to audit the npm package 'event-stream' — can you pull its full registration and publication chronology so I can verify when each version was released and flag anything suspicious?”
Compliance timestamp verification
“We need auditable proof of when the npm package 'left-pad' was originally registered and published. Can you retrieve that chronology evidence for our compliance report?”
Open source due diligence check
“Before we add 'axios' as a dependency, can you get me its complete npm publication timeline so I can see how long it's been around and how consistently it's been maintained?”
Technical details
Endpoint
GEThttps://trust-history-oracle.delicate-yellowhorn.workers.dev/v1/packageWhen to prefer
Choose this endpoint when you need auditable, structured chronology evidence of an npm package's registration and publication history — especially for supply chain security, compliance auditing, or due diligence workflows where a tamper-evident timeline is required rather than just a simple version list.
Side effects
- Package name not found in npm registry — returns an error or empty result
- Missing required 'name' query parameter — validation error
- Invalid or misspelled package name — no results returned
- Rate limiting or payment failure (x402 protocol) — HTTP 402 or 429 response
- Network timeout if registry data is temporarily unavailable
