# Claim a domain Keyless installs collect data under the hostname. Verifying the domain makes it yours, back to the first session. 1. Add the site in [HQ](https://app.doubleagent.so/sites/new), or open the `claim_url` the CLI and install-check print. 2. Prove control with one method: | Method | Put this | Where | |---|---|---| | DNS | TXT `da-verify=` | `_doubleagent.` (on the apex it covers subdomains) | | Meta tag | `` | Home page `` | | File | `da-verify=` | `https:///.well-known/doubleagent.txt` | | Script | Your site's `pk_…` in the live page HTML | Any page | 3. Press **Check now** (or `npx @doubleagent-so/cli verify-domain --method dns`). You get `{ "verified": true, "claimed": { "sessions": 1284 } }`. - Unclaimed data is kept 30 days: aggregates, plus up to 1,000 non-human sessions per hostname. - Once verified, keyed beacons are only accepted from verified hostnames (`403 origin_not_allowed`). - Don't want the history? Settings › Discard pre-claim data (`DELETE /v1/sites/:id/preclaim`).
