Credits & Billing

ParalonCloud runs on a single credit balance. You top it up once, and the same balance pays for everything on the network — GPU rentals and inference alike. There's no subscription and no monthly minimum; you pay only for what you use.

Topping up

In an organization, credits are the organization's: a top-up made while you work in it goes to its balance, and what its members spend comes out of it (see Organizations). Your personal balance is separate. Owners, Admins and Billing members can add credits; a card receipt and invoice go to the member who paid, with the company's details given at checkout.

Add credits on the Add Credits page. Pick an amount, then a payment method:

• Card: Visa, Mastercard, Amex or Apple Pay, on Stripe's secure checkout. Your card details go to Stripe, never to us, and you get a receipt by email. VAT is added on top at checkout where it applies: customers in Romania, and individuals elsewhere in the EU, pay 21% Romanian VAT; EU businesses with a valid VAT number (reverse charge) and everyone outside the EU pay none. Your credits are always the amount you chose, before VAT.
• Crypto, by transfer: send USDC or USDT on Solana to your own deposit address, from an exchange or any wallet. Choose Crypto, then Transfer USDC or USDT on Add Credits to get the address; it is yours and never changes, so later you can send to it without visiting the site (it is also shown in Settings). Credits appear about a minute after the transfer confirms. Minimum $10: smaller amounts are held and credited once your total reaches $10. Send only USDC or USDT on the Solana network to this address.
• Crypto, with a connected wallet: USDC or USDT on Solana or Ethereum, paid from Phantom, Solflare or MetaMask in the browser.

The minimum top-up is $10. Credits are added as soon as the payment clears, they never expire, and they are non-refundable: top up what you plan to use.

Paying by USDC or USDT transfer

For USDC or USDT held on an exchange (Binance, Coinbase, Kraken, OKX, ...) or in any wallet, with nothing to connect in the browser:

1. On Add Credits choose Crypto, then Transfer USDC or USDT. You get a deposit address that belongs to your account.
2. Send USDC or USDT to it on the Solana network. On an exchange, pick Solana (SPL) as the withdrawal network.
3. Credits appear about a minute after the transfer is confirmed, and you get a notification. 1 USDC or 1 USDT = 1 credit; we charge no fee (your exchange may charge its own withdrawal fee, which reduces what arrives).

Good to know:

• The address is permanent. Save it in your exchange's address book and send to it whenever you want more credits; you don't need to come back to the site first. It is also shown under Settings → Account Information.
• Minimum $10. A smaller transfer is not lost: it is held and credited as soon as your transfers add up to $10. Sending $4 and later $6 credits $10.
• What arrives is what you are credited, whatever amount you picked on the page.
• Only USDC or USDT on Solana. Another token, or USDC or USDT sent on Ethereum, Tron, Base or another network, does not reach this address and cannot be credited. If that happens, contact us with the transaction link and we will tell you what can be recovered.
• The QR code opens a Solana wallet app (Phantom, Solflare) with the address and USDC filled in. For USDT, or on an exchange, copy the address instead.

How rentals are billed

GPU rentals are pay as you go, billed per minute:

• A short 1-hour balance is required up front to open a session — this reserves room so a rental can't run your balance negative.
• You're charged only for the minutes you actually use, not the reserved hour.
• Each node's hourly rate is either the platform price for its GPU or a custom price set by its provider — whatever is shown on the Rent page is what you pay.
• The rate is locked when your rental starts — price changes, by the provider or the platform, never affect a running session.
• Stop anytime from My Rentals. Billing ends when the rental ends.

How a rental splits

Every rental price is divided between the provider and the platform:

Party	Share of each rental
Provider	80% — always
Platform fee	14%–20%
Referrers	up to 6% (15% of the platform fee per referred side)

A few things worth being clear about:

• Providers always keep 80%. Your share for hosting never changes.
• The platform fee is up to 20%.
• Referrals made before the program closed to new referrals (20 October 2026) are paid out of the platform fee, never the provider's 80%, until their 12 months end. See Referrals.

How inference is billed

Inference is billed per token, from the same credit balance, at the list price of the model you call. What you pay depends on the type of API key the request came in on. There are three.

Key type	Who it is for	What it costs	Limits
Free	trying the API	nothing — a 250,000-token trial, counted across every request the key makes, for the life of the key, plus 5 images a day	one free key per account, 20 requests/min, 2 images/min
Premium	building on the API	per token and per image, at list price, from your credits	as many keys as you want, 300 requests/min, 16 in flight, 300 images a day
Partner	organisations with their own agreement	metered, invoiced outside the platform	set up per email domain — write to us

The free trial

Unlocking it. The trial is free, and it takes one step to show there is a person behind the account. In the Console, choose any one of:

• A post on X — post with a mention of @ParalonCloud (the Console opens X with the text ready), then paste the link to the post.
• GitHub — sign in with GitHub, or connect a GitHub account, that is at least 30 days old. We read the public profile only.
• Discord — join the ParalonCloud server and link a Discord account at least 30 days old.

Each X, GitHub or Discord account unlocks one trial. You can skip the trial entirely: add credits and create a premium key.

Every account can hold one free key. It carries a trial of 250,000 tokens (raised from 100,000 on 13 September 2026, for existing keys too) — input and output added together — and every request draws from it. The Console shows how much of the trial is left. When it is used up, requests on that key are refused with a 402 (free_quota_exhausted) until you create a premium key. The free key cannot be revoked; if you lose it, regenerate it from the Console and the trial balance stays.

Images are part of the trial too: a free key can render 5 a day, at most 2 a minute, and they are not charged.

Premium keys

A premium key bills each request the moment it completes: tokens in × input price + tokens out × output price, to eight decimals, deducted from your credits. Images are priced per image. Requests sent through the Batch API are billed at 50% of list price, from the same credits, when each one completes; requests in a batch that fail are not billed. You can create as many premium keys as you need, name them per project, and see what each one has cost under Usage in the Console.

A request is refused up front, with a 402, if your balance cannot cover it. Nothing is ever charged for a request that failed.

Prices

Prices are per model and are shown in the Console under Available Models before you pick one. Today, per million tokens:

Model	Input	Output
qwen3.8-27b	$0.12	$1.70	vision, tool calling, 131k context
qwen3-3b	$0.05	$0.20	16k context
z-image-turbo	—	—	$0.003 per image

Every chat completion response includes a usage block (prompt_tokens, completion_tokens, total_tokens), so a request's cost can be worked out from the response alone.

Where the money goes

The split is the same as for rentals: 80% of every request goes to the provider whose GPU served it, credited the moment the request completes, and the platform keeps 20%. Requests on free keys draw on the trial, not on credits, so they carry no split. The mechanics are described in Every Inference Request Pays the GPU That Ran It.

Watching your balance

• Rentals — see live consumption and remaining balance under My Rentals.
• Inference — track requests, tokens and credits spent per API key and per model under Usage in the Console; free keys show the trial remaining.
• History — every top-up and charge is listed in your Transactions. Inference is shown as one line per day, with the request count, tokens and models; the per-request records sit underneath and are what the balance is computed from.
