| model | ClaudeStore (in/out per 1M) | Anthropic |
|---|---|---|
| haiku-4.5 | $0.70 / $3.50 | $1 / $5 |
| sonnet-4.6 | $2.10 / $10.50 | $3 / $15 |

How Claude API Pricing Works
Claude API pricing is based on tokens — the basic units of text that the model processes. Every request has two components: input tokens (what you send) and output tokens (what Claude generates). You pay for both.
On ClaudeStore, credits are deducted from your balance based on actual token consumption per request, with token rates set exactly 30% below Anthropic's official prices for the same models.
What Are Tokens?
A token is roughly 4 characters of English text, or about ¾ of a word. For example:
- "Hello, world!" ≈ 4 tokens
- A 1,000-word article ≈ 1,300 tokens
- A typical code file ≈ 500–2,000 tokens
Token Categories
| Category | What It Is | Relative Cost |
|---|---|---|
| Input (uncached) | Standard input tokens sent to the model | Base rate |
| Output | Tokens generated by Claude in the response | 3–5× input rate |
| Cache Write | Input tokens written to prompt cache (first request) | 1.25× input rate |
| Cache Read | Input cached from a previous request | 0.1× input rate |
Per-Model Pricing
Different Claude models have different price points. All ClaudeStore rates below are 30% below Anthropic's official rates. Rates are per million tokens (MTok):
| Model | Input / 1M | Output / 1M | Anthropic (In/Out) | Best For |
|---|---|---|---|---|
| Claude Opus 4.7 | $3.50 | $17.50 | $5 / $25 | Flagship reasoning, 1M-context tasks |
| Claude Opus 4.6 | $3.50 | $17.50 | $5 / $25 | Heavy reasoning, complex refactors |
| Claude Sonnet 4.6 | $2.10 | $10.50 | $3 / $15 | Coding, general tasks, best value |
| Claude Haiku 4.5 | $0.70 | $3.50 | $1 / $5 | Fast responses, classification, autocomplete |
Cache pricing: Cache Write = 1.25× input, Cache Read = 0.10× input. Same multipliers as Anthropic, applied to our discounted base rate.
Cost Calculation Example
Here's how to estimate the cost of a typical request using Claude Sonnet 4.6 at ClaudeStore's public rate ($2.10/MTok input, $10.50/MTok output):
Input: 2,000 tokens × $2.10 / 1,000,000 = $0.0042
Output: 500 tokens × $10.50 / 1,000,000 = $0.00525

Total: $0.00945 per request
At this rate, $5 (1,000 credits) gets you ~529 similar requests.
That same request would deduct about 1.89 credits.Tips to Reduce Costs
1. Choose the Right Model
Don't use Opus for tasks that Sonnet or Haiku can handle. Sonnet is 5× cheaper than Opus and handles most coding and general tasks excellently.
2. Use Prompt Caching
If you send the same system prompt repeatedly, enable prompt caching. After the first request, cached tokens cost only 10% of the standard input rate.
3. Optimize Prompt Length
Remove unnecessary context from your prompts. Shorter prompts = fewer input tokens = lower cost.
4. Set Per-Key Limits
Use ClaudeStore's per-key credit limits to prevent unexpected spending, especially on development and testing keys.
5. Monitor Usage
Check the ClaudeStore dashboard regularly to understand your consumption patterns and optimize accordingly.
Is ClaudeStore the Cheapest Claude API Option?
ClaudeStore offers one of the most affordable ways to access the Claude API. Unlike Anthropic's direct API, there's no minimum spend, no waitlist, and no KYC. You can start with as little as $5 in credits.
Because ClaudeStore uses the same underlying API, you get identical model quality at competitive rates. Combined with prompt caching (90% savings on repeated prompts), it's a cost-effective choice for developers and teams looking for a cheap Claude API key without compromises.
