Billing

How LLM247's prepaid credit system works — deposits, deductions, and balance management.

Prepaid Credit Model

LLM247 operates on a pay-as-you-go basis. There are no recurring charges, no seat fees, and no usage minimums. You deposit credit into your account; that credit is drawn down as you make API calls.

The flow is straightforward:

Deposit credit — Add funds to your account from llm247.net/billing
Call the API — Before paid upstream work starts, the API reserves a conservative request budget from your available credit. After authoritative usage arrives, it settles the actual cost and releases unused funds.
Track spend — The dashboard shows live balance, per-request cost breakdowns, and model-level usage aggregates
Reload when needed — Your balance carries forward indefinitely; top up whenever it runs low

How Deductions Are Calculated

Token-priced models (chat / completion)

For text models — including OpenAI GPT-5.6, Anthropic Claude, Google Gemini, and every open-weight option in the catalog — token cost is calculated separately for input and output, then summed:

request_cost = (input_tokens  / 1,000,000) × input_rate
             + (output_tokens / 1,000,000) × output_rate

Worked example — calling gpt-5.6-terra with a 500-token prompt that generates a 200-token reply:

cost = (500 / 1,000,000) × $1.250
     + (200 / 1,000,000) × $7.500
     = $0.0006250 + $0.0015000
     = $0.0021250

Providers may return a usage field containing token counts. Streaming clients should request usage reporting. Missing or incomplete provider usage is not treated as a free completed request: the reservation remains held until it can be reconciled against provider evidence.

{
  "usage": {
    "prompt_tokens": 500,
    "completion_tokens": 200,
    "total_tokens": 700
  }
}

A confirmed rejection before billable work releases its reservation. Timeouts and ambiguous failures may retain a hold because the provider may have performed work.

Payment Methods

We support two payment methods:

Card — All major credit and debit cards, processed securely via Stripe.
Crypto — Available currencies are shown at checkout and processed via Plisio. You'll be redirected to the payment partner to complete the transaction.

Checking Your Current Balance

From the portal: the balance page shows available credit. Funds reserved for in-flight or unresolved requests are not available for another request and are not counted as collected usage until settlement.

The authenticated portal balance endpoint is /api/user/balance; it uses a portal session token, not an inference API key. The legacy /v1/dashboard/billing/credit_grants endpoint is not supported.

Insufficient Funds and Financial Holds

A positive balance alone does not guarantee admission. If available credit cannot cover the request budget, the API rejects the request before paid upstream execution with HTTP 402 and an insufficient_quota error. A fully depleted wallet is rejected by authentication with HTTP 429 and the same error type.

Concurrent requests share the same available funds: they cannot reserve the same money twice. Reduce an explicit output-token limit or add funds if the request budget exceeds your available balance.

Requests containing features without a prepaid pricing policy (such as provider-hosted search or remote media) return HTTP 400 with invalid_request_error, not insufficient_quota. Declared client-side function tools and bounded Kimi reasoning use the model's token rates; they do not spend separate hosted-tool credits.

Account-level API suspensions return HTTP 403 with account_suspended; replacing or re-enabling API keys does not remove the suspension. Adding credit does not automatically clear a financial hold. Contact support with the request or payment reference for reconciliation.

Refund and Adjustment Policy

Credit purchases are non-refundable. We recommend starting with a smaller deposit to validate your integration before committing to a larger amount.

If a technical fault on our end caused an incorrect deduction, use the contact form with the affected request IDs and timing. We review each case individually.
