Domains

Use the public Registrar API for unauthenticated discovery. Use the installed Vercel CLI for account and project operations, or the REST API for structured automation. vc and vercel are equivalent.

Registration, Vercel team ownership, project assignment, and authoritative DNS are separate. Connecting an already-owned domain does not require buying it or transferring its registration.

Search before asking for credentials

Start exact-name research with one request returning availability and pricing together:

curl --fail-with-body --silent --show-error \
  https://api.vercel.com/v1/registrar/domains/search \
  --header 'Content-Type: application/json' \
  --data '{"domains":["example.com","example.dev","example.app"]}'

Send 1–200 exact domain names per request. The endpoint checks the supplied names; it does not generate suggestions. Generate candidates from the user's naming constraints, then batch them. No Vercel account, token, or project link is needed.
