Domains

Point a domain at your Cantila app and the platform auto-creates the DNS records, issues SSL, and configures email authentication. You can also search and register new domains across major TLDs at cheapest-in-market pricing.

Attach a custom domain (live)

Add a domain as a project alias and Cantila configures everything to serve your app over HTTPS:

curl -X POST https://api.cantila.app/v1/projects/proj_123/aliases \
  -H "Authorization: Bearer $CANTILA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "domain": "app.example.com" }'

When you attach a domain, Cantila:

1. Creates the DNS records that point the domain at the app.
2. Issues and renews an SSL certificate automatically.
3. Configures email authentication records (SPF / DKIM) for the sending domain.

Register a domain (phase 2)

The registrar covers search, register, transfer, and renew across major TLDs, with free WHOIS privacy and cheapest-in-market pricing:

Search and quote are available; the purchase/transfer/renew checkout is Phase 2.

# Search availability across TLDs
curl "https://api.cantila.app/v1/domains/search?q=acme" \
  -H "Authorization: Bearer $CANTILA_API_KEY"

# Quote a specific domain
curl "https://api.cantila.app/v1/domains/quote?domain=acme.io" \
  -H "Authorization: Bearer $CANTILA_API_KEY"

Once registered, Cantila auto-creates the records to point the domain at your app, issues SSL, and configures email auth — no manual DNS.
