Expired Domains API — 19 Auction Platforms in One Search

The fastest way to query the expired-domains market from code. One API call returns aggregated inventory from 19 live auction platforms (Dynadot, GoDaddy, DropCatch, Catched, Gname, SnapNames, Nicsell, BloomUp, Subreg, WebExpire, Park.io, NameSilo, SEO.Domains, NameShift, DomainLore, Rakko, UK Backorder, Gnews Domains, Backorders Domains) — every domain pre-enriched with quality score, Domain Authority, backlinks, referring domains, Wayback age, language, GBP detection, historical tech stack, and 5-year traffic estimate.

Sits on top of CatchDoms.com, which also exposes a deleted-domains catalog (100k+ aged ccTLDs at registry price) and a weekly pending-delete inventory across 125+ TLDs — both reachable via the same API.

Why use this actor

• One endpoint, 19 sources. No more polling DropCatch + GoDaddy + Dynadot + … and merging results. The catalog is refreshed daily and pre-deduplicated.
• SEO data already attached. Every row ships with the metrics that matter for an expired-domain buyer (DA, TF, CF, backlinks, referring domains, Wayback age, indexed pages, GBP, historical CMS) — no chaining into Ahrefs / SEMrush / Majestic.
• Filterable. 25+ query parameters — by TLD, score, DA, TF/CF, age, language, keyword, price range, category, has-backlinks, has-GBP, has-bids, etc.
• Free tier on Apify. 50 results per run, first 10 names visible, the rest masked to invite a free CatchDoms signup for unmasking.

    "age_min": 10,
    "has_backlinks": true,
    "limit": 50

    "rd_min": 50,
    "da_min": 0,
    "limit": 50
}

Direct API access

Apify is the easiest entry point. If you want the full quota + every field, every domain unmasked, and no limit=50 cap, use the CatchDoms REST API directly. Same parameters, same response shape, no daily quota:

curl "https://catchdoms.com/api/domains?score_min=50&has_backlinks=1&per_page=100" \
    -H "Authorization: Bearer YOUR_CATCHDOMS_API_KEY"

Generate your API key at catchdoms.com/api. Full reference at catchdoms.com/docs.

Why CatchDoms instead of scraping

Most "expired domains scrapers" hit one site (DropCatch or GoDaddy) and return raw HTML or a thin JSON. We aggregate 19 platforms + 2 enrichment surfaces (deleted ccTLDs, pending-delete inventory across 125+ TLDs) + 14 SEO metrics per domain. The catalog is refreshed daily, deduplicated, scored — you go from API call to shortlist in one round-trip.

• Free signup to unlock all 50 names per call → catchdoms.com/register
• Pro plan for full SEO metrics, CSV export, email alerts, direct API access → catchdoms.com/pricing
• Authority for the deleted-domains catalog (100k+ aged ccTLDs)
• Authority+ for the weekly pending-delete inventory across 125+ TLDs
