Domain availability and price API

domain.search

live

Check which domains are available and what they cost to register through Jell: a name across common TLDs, or one exact domain.

live coverage

Name.com: all inputs ✓

✓ marks a combination proven with a real provider call. Others are wired and unit-tested; their first live run verifies them.

Billing

Unit: per_search · unmatched results billed: no

The exact quote is returned by /v1/inspect before every call and held with headroom on execution. The quote is the price floor: if the provider's actual cost overruns it, the run bills the overrun at the same rate, never above the hold. The unused part of every hold is released.
