Create or update a TXT record for domain verification. Used for services like Vercel (_vercel) and Netlify that require DNS-based ownership proof. The record is placed at the root domain under the prefix you give (e.g. _vercel.sitey.my), alongside the other owners' values — that is the name Vercel reads for a subdomain of sitey.my.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| subdomain | string | yes | Subdomain name (e.g. 'demo') |
| domain | string | yes | Root domain (e.g. 'sitey.my') |
| host_prefix | string | yes | TXT record host prefix (e.g. '_vercel' for Vercel verification) |
| value | string | yes | TXT record value (the verification token) |
| root_level | boolean | no | No longer supported — TXT records are always written at the root domain. Passing true returns an error. |
| owner_token | string | no | The owner token you were given when you created the record (starts with anon_). Omit it only if you have an API key, or if the record predates tokens and was claimed from this same IP address. Creating without one mints a new one and returns it once. |
