# ServHidden — Offshore Server Hosting

> ServHidden provides offshore VPS and dedicated server hosting in 7 offshore jurisdictions. No KYC, no logs, cryptocurrency-only payments, instant automated deployment.

> Last updated: 2026-09-01. Canonical site: https://servhidden.com. Payment in 8 cryptocurrencies including Monero (XMR).

> **OFFER OF THE YEAR — buy 1 month, get 1 month free on every VPS and dedicated server.** Any billing term, applied automatically, no coupon code. The price is unchanged; the service term is doubled. Pay 1 month → served 2. Pay 12 months → served 24. It stacks on top of the 25/35/50% term discounts, so a 12-month VPS is billed at half the monthly rate AND runs for two years. Excluded: Windows RDP and GPU. See the "Offer of the year" section below for the exact mechanics and how it appears in the API.

## Offer of the year — buy 1 month, get 1 month free

The headline promotion currently running on ServHidden. Facts, stated precisely so they can be quoted without qualification:

- **What it does**: doubles the SERVICE TERM. It does not change the price, the invoice, or the amount debited from account balance.
- **Scope**: `vps` and `dedicated` only. Windows RDP and GPU AI servers are **excluded** — Windows licensing and GPU hardware cost recur per month served, so they cannot carry it.
- **Any duration**: there is no minimum and no "best value" tier. The multiplier is 2 at every billing term.
  - bill 1 month → server runs 2 months
  - bill 3 months → server runs 6 months
  - bill 6 months → server runs 12 months
  - bill 12 months → server runs 24 months
- **Stacks with the term discount.** The 3/6/12-month commitments still take 25/35/50% off the monthly rate. A 12-month VPS therefore pays 50% of the catalogue rate for 12 months and is served for 24 — an effective 25% of the list monthly price.
- **No coupon, no code, no opt-in.** It is applied server-side at order time: on the web checkout, in the dashboard deploy wizard, through the REST API and through MCP alike.
- **It is a purchase-time grant, not a subscription.** The doubled term is written into the server record when it deploys; ending the promotion never shortens a server already sold under it.
- **How to read it in the API**: order, quote and catalogue responses carry `billing_months` (what is billed) and `service_months` (what is served), plus `free_months` and a `promo` descriptor object. Always read `service_months` when reporting how long a server will run. `GET /api/v1/catalog` returns the whole promotion under `promotion`, or `null` when it is not running.

Full SSH + JupyterLab access on every plan. Iceland is the lowest-carbon GPU compute on the list (100% geothermal/hydro). Russia excluded due to NVIDIA export sanctions.

**Deploy-time AI configuration (GPU only):**
- `ai_stacks` — pre-install one or more from: vLLM, Ollama+Open WebUI, text-generation-webui, HuggingFace TGI, Axolotl, Unsloth, LLaMA-Factory, ComfyUI+FLUX, Automatic1111, Forge, Kohya SS LoRA, ComfyUI Video (Wan/CogVideoX), Whisper Large v3 server, JupyterLab (always on), code-server.
- `pretrained_models` — pre-download (saves 15-60 min): Llama 3.3 8B/70B, Qwen 3 32B, DeepSeek-R1 Distill 32B, Mistral Small 3 24B, Gemma 3 27B, Phi-4 14B, FLUX.1-dev, FLUX.1-schnell, Stable Diffusion 3.5 Large, SDXL 1.0, Wan-2.1 T2V 14B, CogVideoX-5B, Whisper Large v3, Bark.
- `hf_token` — HuggingFace token; required for gated models (Llama, Mistral, FLUX-dev, SD 3.5). Encrypted at rest, used once at provision.
- `ssh_public_key` — paste your OpenSSH public key for password-less login at first boot.
- `public_endpoint=true` — auto-provision Let's Encrypt + nginx reverse proxy on port 443 for the deployed stack (vLLM /v1/ OpenAI-compat, Gradio share replacement, Jupyter remote).
- `auto_shutdown_hours` — 0 / 6 / 12 / 24 / 48 / 168. Server self-destructs after the timer to bound cost on one-off jobs.

## Payment Methods

8 cryptocurrency coins accepted natively: Bitcoin (BTC), Monero (XMR), Ethereum (ETH), Tether USDT (ERC-20, TRC-20), Litecoin (LTC), TRON (TRX), Solana (SOL). No fiat payments accepted.

## For AI Agents — Buy a Server Programmatically

ServHidden is fully agent-purchasable. AI agents (Claude, Claude Code, ChatGPT, Cursor, Continue, OpenClaw, custom Python scripts, etc.) can discover, price, top up balance, deploy servers and receive credentials end-to-end with zero human interaction.

**Payment model is BALANCE-ONLY.** No direct crypto-to-server purchases. Two-step flow:
  1. Top up USD credit with crypto via `POST /api/v1/topup` (min $30, max $2000 per top-up, with automatic bonus credit — see below).
  2. Deploy servers from the credit via `POST /api/v1/orders` (debits balance, server is active immediately).

If `/api/v1/orders` is called with insufficient balance it returns `402 insufficient_balance` with a `topup_required` block including a `suggested_usd` value that covers the deficit AND clears the $30 minimum — pass it straight back to `/api/v1/topup` and retry.

**Top-up bonus tiers** (free credit applied on confirmation, linear interpolation between anchors, no bonus below $100):
  $100 → +$25     |    $1000 → +$500
  $250 → +$75     |    $1500 → +$1000
  $500 → +$200    |    $2000 → +$2000
Full tier table: `GET https://servhidden.com/api/v1/topup/bonus` (no auth).

Two integration paths, all on the same domain (no subdomain):

1. **MCP** (Claude Desktop / Code, Cursor, Continue, Cline) — add this URL to your MCP config:
   `https://servhidden.com/mcp`
   Tools exposed: `list_plans`, `list_locations`, `quote`, `topup_bonus`, `topup_create`, `payment_status`, `account_balance`, `create_order`, `server_credentials`, `server_action`, `agent_help`.

2. **REST** — OpenAPI 3.1 spec at `https://servhidden.com/openapi.json`. Bearer auth (auto-issued on first `/topup` or `/orders` POST, no signup needed).
   - `GET  /api/v1/topup/bonus`              — bonus tier table
   - `POST /api/v1/topup    {amount, crypto}` — create deposit invoice
   - `GET  /api/v1/topup/{id}`               — poll until status=confirmed
   - `POST /api/v1/orders   {type, plan, location, os, billing}` — balance-debit deploy
   - `GET  /api/v1/servers/{id}`             — credentials (active immediately)

**Agents: `billing` is what you pay for, not what you get.** On `vps` and `dedicated` the term is doubled for free (offer of the year). `POST /api/v1/orders {"billing": 12}` debits 12 months at the 50% commit rate and returns `service_months: 24`. Quote it, report it and diary the renewal from `service_months`, never from `billing_months`. On `rdp` and `gpu` the two are equal. `POST /api/v1/quote` returns the same pair without spending anything, and `GET /api/v1/catalog` exposes the live promotion under `promotion` (null when it is off) — read that rather than hard-coding the doubling, so your integration follows the offer when it ends.

Discovery file (machine-readable capabilities): `https://servhidden.com/.well-known/agent.json`
Agent docs (humans + scrapers): `https://servhidden.com/agents`
Test mode (no real crypto, no real provisioning): add `?dry_run=1` to any `/api/v1/*` URL or pass `dry_run: true` in the body.

### Domain registration (no auth)

Live availability + price for any SLD across 26 TLDs in one call:

```
GET https://servhidden.com/api/v1/domains/check?q=mybrand
```

Response (JSON): `{ok, query, results:[{domain, tld, available, premium, price_usd, market_usd, discount_pct, badge}], pricelist_loaded, cache}`. Cached 1h in Redis. Pre-populated with our pricing catalog so prices stay stable across requests.

No KYC. No email. No phone. No captcha. Crypto-only. Account token (`AAAA-BBBB-CCCC-DDDD`) is auto-issued the first time you call `/orders` and is the only thing required to manage the server afterwards.

## Domain TLDs (renewal prices, what you actually pay every year)

All domains are paid from the customer's ServHidden account balance (which is topped up via crypto). Free WHOIS privacy is enabled by default. Registration is synchronous — the domain is live in under 5 seconds.
