# How to buy a Claude API key

You do not need an Anthropic account, an invite, or a company card to buy a Claude API key. With apiToken.sale you top up prepaid balance, generate one key, and call the same Anthropic Messages API at a discount — instant Claude API access for Opus, Sonnet and Haiku.

## Get your key in three steps

1. Create a free account and open the dashboard — no approval or waitlist.
2. Generate one API key (it looks like sk-pool-…). The same key works across every supported Claude model.
3. Point any Anthropic-compatible tool at https://api.apitoken.sale and send requests to /v1/messages with the x-api-key header.

## How payment works

Top up any whole-dollar amount you like — there is no fixed product catalog. Your balance is prepaid, never expires, and is spent only when API requests run.

- Pay by bank card or with cryptocurrency through a secure checkout provider.
- Every request is converted to official Anthropic API spend, then your active discount is applied.
- B2C accounts start 60% below official spend and progress up to 80% off as you top up more.

## What you can do with the key

One key unlocks the full supported Claude line — Opus, Sonnet and Haiku — across Claude Code, Cursor, Cline, Continue, Zed and the official Anthropic SDKs. Nothing about the protocol changes; only the price does.

## Which Claude models and tools you get

One Claude API key unlocks the full supported line on a single balance, and works in every Anthropic-compatible tool.

- Models: Claude Opus 4.8 and 4.7, Sonnet 5 and 4.6, Haiku 4.5.
- Tools: Claude Code, Cursor, Cline, Continue, Zed and the Anthropic SDKs.
- Formats: the Anthropic Messages API with streaming and tool use.

## Frequently asked questions

### Do I need an Anthropic account to buy a Claude API key?

No. apiToken.sale issues its own key and balance, so you can start without an Anthropic account, invite, or approval.

### How fast is the key active?

Instantly. You generate the key in the dashboard and it works on the next request — there is no waitlist or manual review.

### How much does it cost to start?

You can top up any whole-dollar amount. New accounts created with Google or GitHub also get $10 of Claude usage at official API prices for free.

### Is this the official Claude API?

Yes — it serves the same Anthropic Messages API and the same Claude models. Only the price and the way you sign up and pay are different.
