How this service works
Internet Archive Wayback Machine CDX index: archived snapshots of a URL or domain (timestamp, original URL, MIME type, HTTP status, length) with a link to each capture. Public, no key; the index lists captures, not page text.
Output
Returns a JSON object containing the queried URL, total snapshot count, the CDX source URL, the retrieval timestamp, and an array of snapshot objects each with: original URL, archive timestamp, direct Wayback Machine archive URL, archived datetime, HTTP status code, MIME type, and content digest hash.
Example use cases
Investigate domain history for OSINT
“I need to research the archive history of suspiciousdomain.xyz — can you check the Wayback Machine and show me up to 20 snapshots so I can see when the site first appeared and how it changed over time?”
Verify past webpage content
“Can you pull the last 10 Wayback Machine snapshots for https://blog.acmecorp.com/product-launch-2019 so I can verify what the page said before it was taken down?”
SEO audit of competitor site history
“I'm doing a competitive analysis — fetch me 15 archived snapshots from the Wayback Machine for competitor.com so I can trace changes to their homepage over the years.”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/search/wayback-cdx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured CDX metadata about archived snapshots of a URL or domain — especially for OSINT investigations, historical content verification, SEO audits, or security research — without needing a signup or API key. Prefer it over direct Wayback Machine scraping because it returns clean JSON with parsed timestamps, status codes, and direct archive links. It pays per call (no subscription), making it ideal for occasional or agent-driven lookups.
Side effects
- URL has no Wayback Machine snapshots (count returns 0, empty snapshots array)
- Invalid or malformed URL input causing a query error
- Limit parameter outside the 1–50 range may be rejected or clamped
- Internet Archive CDX API downtime or rate limiting causing upstream failure
- Network timeout if the CDX service is slow to respond
