**Check domain availability** · Read-only

Check whether a domain can be registered for outreach and what it costs. Call it before add_outreach_domain, which uses this quote (valid for 6 hours). Returns domain, available, price and renewalPrice (USD per year, registration quote), premium and a rating of the name. The amount charged at purchase can be higher than this registration quote; the dashboard checkout shows the final total. Endings that require multi-year registration are refused with an error; HTTP 503 means the lookup was busy, try again shortly. Not available with a website-scoped key.
