# Pricing

DOS AI uses a simple **pay-as-you-go** pricing model. You only pay for the tokens you use, with no minimum commitments, no monthly fees, and no hidden charges.

## Zero-Markup Policy

DOS AI operates on a strict **Zero-Markup Policy**:

* **100% Provider Published List Price**: We sell cloud and third-party models at exactly 100% of the upstream provider's official published list price (`markup_pct = 0`).
* **No Hidden Fees or Surcharges**: You never pay more for tokens than you would by calling providers directly.
* **Single Transparent Bill**: Consolidate multiple model providers into one unified account, API key, and balance without paying markup penalties.

***

## Free Tier & Promotional Credits

Every new account receives **$5.00 in free credits** to get started. This is enough for substantial experimentation and prototyping before you need to add funds.

| Model                            | Approximate Free Usage                              |
| -------------------------------- | --------------------------------------------------- |
| **GPT-6 Luna**                   | \~50 million input tokens (or 10M output tokens)    |
| **DOS Curated Endpoint (`dos`)** | \~71 million input tokens (or 10M output tokens)    |
| **DeepSeek V4.1 Flash**          | \~16.6 million input tokens (or 4.1M output tokens) |
| **Gemini 3.8 Flash**             | \~6.3 million tokens                                |

> Free credits do not expire. No credit card is required to start.

### Cash Gate & Promotional Credit Policy

To prevent multi-account abuse on upstream cloud providers while offering friction-free onboarding, DOS AI implements an account-level **Cash Gate**:

* **First-Time / Unfunded Accounts**: Promotional credits (welcome bonus, coupons, referral rewards) can be used freely for DOS AI's curated in-house endpoints (`model: "dos"`).
* **Cash Gate Unlock**: Once an account completes its first real deposit/top-up (minimum $5.00), the Cash Gate is permanently unlocked for that account. All remaining promotional credits, bonus balances, and coupons can then be spent across **any model in the entire catalog**, including frontier third-party providers.

## Per-Token Pricing

Pricing is calculated per **1 million tokens** (input, output, and cached input). All rates are statically database-driven from the Supabase catalog (`dosai.model_pricing`) and strictly follow official provider published prices.

### Smart Router & Curated Platform Models

| Model                            | Provider                   | Input Price (per 1M) | Output Price (per 1M) | Cached Input (per 1M) | Billing Policy                               |
| -------------------------------- | -------------------------- | -------------------- | --------------------- | --------------------- | -------------------------------------------- |
| **Smart Router (`auto`)**        | Dynamic                    | Variable             | Variable              | Variable              | Billed at target model's exact rate          |
| **DOS Curated Endpoint (`dos`)** | DOS.AI (Singapore cluster) | **$0.07**            | **$0.50**             | —                     | Wholesale fixed rate (Singapore GPU default) |

*Note: Calls targeting `model: "dos"` execute on the Singapore GPU cluster at the fixed $0.07/$0.50 rate. Direct calls to individual curated engines (e.g. `gpt-6-luna`, `gemini-3.8-flash`, `deepseek-v4.1-flash`) or auto-escalations via `auto` are billed at each target engine's exact published rate.*

### Prompt Caching Savings

For supported models (including GPT-6 series, DeepSeek V4.1, Qwen 3.8, and Meta Muse), repeated prompt prefixes automatically benefit from prompt caching:

* **GPT-6 Luna**: Cached input tokens are billed at **$0.01 / 1M tokens** (90% savings).
* **Qwen 3.8 Flash**: Cached input tokens are billed at **$0.016 / 1M tokens** (89% savings).
* **Qwen 3.8 27B**: Cached input tokens are billed at **$0.10 / 1M tokens** (80% savings).
* **Qwen 3.8 Max**: Cached input tokens are billed at **$0.25 / 1M tokens** (87.5% savings).
* **DeepSeek V4.1 Flash**: Cached input tokens are billed at **$0.03 / 1M tokens** (90% savings).
* **Meta Muse (`muse-wonder-1.0`, `muse-spark-1.3`)**: Cached input tokens are billed at **$0.04 / 1M tokens** (up to 89% savings).

***

### What is a Token?

A token is roughly 3-4 characters of English text, or about 0.75 words. For example:

* "Hello, world!" = approximately 4 tokens
* A typical 500-word blog post = approximately 650-700 tokens
* A full 128K context window = approximately 96,000 words
* A 1.05M context window = approximately 780,000 words

***

## How Billing Works

1. **Add credits** to your account via the [dashboard](https://app.dos.ai).
2. **Make API calls** as normal. Each request deducts tokens used from your balance.
3. **Monitor usage** in real time through the dashboard billing page.

Token usage is calculated after each request completes. Both input tokens (your prompt) and output tokens (the model's response) are counted and billed at the rates above.

### Usage Tracking

Every API response includes a `usage` object showing exactly how many tokens were consumed:

```json
{
  "usage": {
    "prompt_tokens": 125,
    "completion_tokens": 320,
    "total_tokens": 445,
    "prompt_tokens_details": {
      "cached_tokens": 100
    },
    "cost": 0.0001725
  }
}
```

You can also view historical usage and spending breakdowns on the [dashboard](https://app.dos.ai).

## Billing History & Receipts

You can view your complete transaction history at any time on the [Billing Dashboard](https://app.dos.ai/billing):

* **Comprehensive Ledger**: View all credit purchases, signup bonuses, referral rewards, refunds, and usage charges in a unified, sortable table.
* **Direct Stripe Receipts & Invoices**: For any card deposit, subscription, or automated recharge processed via Stripe, click the **Receipt / Invoice** button to instantly open official Stripe receipts and hosted invoice PDFs in a secure new tab.
* **Privacy Protection**: Referral commissions automatically redact internal referee identifiers (`[redacted]`) to safeguard team and member privacy.

## FAQ

### Do free credits expire?

No. Your free credits remain in your account until used.

### Is there a minimum top-up amount?

The minimum credit purchase is $5.00.

### What happens when my balance reaches zero?

API requests will return a `402 Payment Required` error. Add credits to resume usage immediately. No data is lost.

### Can I set spending limits?

Yes. You can configure monthly spending alerts and hard limits in the dashboard settings.

### Are there any hidden fees?

No. You pay only for the tokens you consume. There are no platform fees, no per-request fees, and no bandwidth charges.

### How can I get a tax receipt or VAT invoice?

For international credit card payments processed via Stripe, you can access official Stripe payment receipts and hosted invoices directly from the **Billing History** table at [app.dos.ai/billing](https://app.dos.ai/billing). For corporate billing or Vietnamese tax invoices (e-invoicing via MISA meInvoice), configure your company legal name, tax code, and registered billing address under [Billing Preferences](https://app.dos.ai/billing?tab=tax).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dos.ai/models/pricing.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
