Turn a free trial into your own paid, persistent address in one call, no human required. Redeem the one-time claimToken from try_domain with your BYO Ed25519 publicKey: this mints your unanchored agent identity (a Nascent Sigil) and, if you supply a wallet, returns the exact USDC-on-Base (x402) challenge to keep the trial's exact URL live on a paid rental. No wallet yet? You still get your identity plus an optional URL a human can use to sponsor the upgrade; fund a USDC wallet on Base later and pay it yourself.

|---|---|---|---|
| claimToken | string | yes | The one-time claim token returned by try_domain / answer_trial_canary. |
