Afternic
Map Afternic domain listings and purchase workflows without assuming an undocumented buyer-side bidding API.
Explore AfternicCompare domain marketplace access routes for Afternic, Sedo, Atom, and Spaceship, with a separate lifecycle guide for domain dropcatch.

A domain integration can discover inventory, manage a seller portfolio, hold a name, initiate a purchase, or track a transfer. Those are different capabilities. Build a matrix for the actions your application needs and attach each one to the official documentation and account permission that support it.
One domain can appear in several provider records. Preserve the normalized name, intended display name, source identifier, listing format, currency, and observation time. Do not overwrite a minimum offer with a fixed price or treat a cached search result as a reservation. The domain marketplace article develops a workflow from discovery to delivery.
Separate a listing, an approved offer or purchase instruction, a provider hold, the commercial outcome, and the final handoff. An acknowledgement only establishes the state the provider actually reported. A timeout should create a reconciliation task rather than an unreviewed duplicate acquisition.
Dropcatch introduces registration observations, service cutoffs, capture results, and potentially a later allocation process. A registry expiry date is not a guaranteed availability time. Keep this route separate from ordinary fixed-price marketplace inventory and use the dropcatch guide to model its additional events.
