Server Hosting

Apply a change quote. Use exactly `execution.input` from `change-server-quote`: `serverId`, `changeQuoteId`, `minimumRemainingSeconds`. - Amount due: buy this skill from the owner wallet named in the quote; the order completes when the change is applied. - Nothing due: run it through daski_use_asset; the receipt (`status: accepted`) means the command was admitted, and get-server shows when it completes. A change keeps the disk, IP, data and installed key; a different machine type stops and restarts the server (paid time is paused meanwhile). Applying the current configuration starts a stopped server within its paid term, and a paid change restores a retained server. A stale quote is refused with `status: refused` before anything changes; request a fresh quote.

Buy a prepaid Linux server (Ubuntu LTS with Docker and Compose) for a number of hours. Inputs: `vcpu`, `ramGiB`, `storageGiB`, `hours` (and `cpu`, if used) exactly as previewed, `planId` from `get-pricing` or the outcome requirements, and `sshPublicKey`: one OpenSSH public key line (never a private key). Provisioning starts after payment and usually takes a few minutes; rental time starts when the server is ready. If capacity is short the paid order keeps retrying - never pay again for the same purchase. Returns: `{ assetId, serverId, access: { publicIp, sshUsername, sshPort, hostKeyFingerprint }, resources, rental: { hourlyRate, paidThrough, deleteAfter }, dns }`. Verify the host key fingerprint on first connection. Password and root SSH logins are disabled; your user has sudo. Inbound TCP 22, 80 and 443 are open. At `paidThrough` the server stops; disk and IP are kept until `deleteAfter` (24 hours later), then deleted for good. Point your domain at `publicIp` with domain-management `set-dns-record` (A record).

Quote a new machine size and/or rental term for a server you own. Free; saving the quote reserves nothing. Owner operations are wallet-authorized through the Daski gateway (daski_use_asset); the provider rejects anonymous access. Inputs: `serverId`, `vcpu`, `ramGiB`, `storageGiB` (must equal the current disk size), optionally `cpu` (the server keeps its CPU class when omitted), `adjustTime`: - `true` - pay nothing: unused value converts into the time it buys at the new rate (omit `hours`). - `false` with `hours` - the desired total remaining term; you pay only the shortfall (at least the minimum change payment), and any surplus becomes extra time. To extend without resizing, request the current resources and a longer term. All remaining credit converts at the new rate. Results above 720 remaining hours are refused. Returns: `changeQuoteId`, the proposed allocation and rate, `amountDue`, estimated remaining time, `minimumRemainingSeconds`, `expiresAt`, and `execution` naming the route and exact input: `purchase` (pay with `payerAddress`, the owner wallet) or `asset-action` (free, via daski_use_asset).

**Destructive.** Permanently delete a server, its disk, data and IP address. Remaining prepaid credit is forfeited; no refund is issued. Owner operations are wallet-authorized through the Daski gateway (daski_use_asset); the provider rejects anonymous access. Inputs: `serverId`, `revision` (from get-server). The first call stages the deletion; after the delay a fresh wallet authorization confirms it, or you can cancel. Refused while a paid or owner operation is in progress or a hold applies. Nothing can be restored afterwards.

Read a server you own: state, resources, access details, unused value, remaining time, paid-through and deletion deadline, hold, traffic, and recent operations with their progress. Owner operations are wallet-authorized through the Daski gateway (daski_use_asset); the provider rejects anonymous access. Input: `serverId`. Works on running, stopped, retained (expired) and deleted servers.

**Destructive.** Reinstall a server from the clean image with a new SSH key, erasing all data on its disk. The server keeps its ID, IP address, disk size and paid time. Owner operations are wallet-authorized through the Daski gateway (daski_use_asset); the provider rejects anonymous access. Inputs: `serverId`, `revision` (from get-server; a changed server refuses the reset), `sshPublicKey` (the new key). The first wallet-authorized call only stages the reset and returns the exact effect summary; after the delay a fresh wallet authorization must confirm it, or you can cancel. The receipt means the reset was admitted; it runs isolated and get-server shows completion and the new host key fingerprint. Works even if the guest broke SSH.

Preview a server's actual allocation and price. Free, no auth, creates nothing. Inputs: `vcpu` (2-16 minimum), `ramGiB` (1-64 minimum), `storageGiB` (16-512 exact disk size), `hours` (1-720), and optionally `cpu`: `dedicated` (default; every vCPU may run at 100% all the time) or `burstable` (cheaper: a guaranteed baseline share of each vCPU with bursts above it, slowed under sustained load; suits websites and light workloads). Returns: the cheapest offered size of that CPU class meeting the minimums, its CPU class and baseline, daily outbound allowance, its location, hourly rate, rental price, the one-time 24-hour retention fee, total price, `planId` and `catalogVersion`; `purchasable: false` with a `reason` when sales are paused or at capacity. Next step: buy `create-server` with the same resources, `planId` and your SSH public key. A changed catalog requires a fresh preview.
