​

Feature-specific pricing

​

Batch processing

The Batch API allows asynchronous processing of large volumes of requests with a 50% discount on both input and output tokens.

Model	Batch input	Batch output
Claude 3.7 Sonnet	$1.50 / MTok	$7.50 / MTok
Claude 3.5 Sonnet	$1.50 / MTok	$7.50 / MTok
Claude 3.5 Haiku	$0.40 / MTok	$2 / MTok
Claude 3 Opus	$7.50 / MTok	$37.50 / MTok
Claude 3 Haiku	$0.125 / MTok	$0.625 / MTok

For more information about batch processing, see our batch processing documentation.

​

Tool use pricing

Tool use requests are priced based on:

1. The total number of input tokens sent to the model (including in the tools parameter)
2. The number of output tokens generated
3. For server-side tools, additional usage-based pricing (e.g., web search charges per search performed)

Client-side tools are priced the same as any other Claude API request, while server-side tools may incur additional charges based on their specific usage.

The additional tokens from tool use come from:

• The tools parameter in API requests (tool names, descriptions, and schemas)
• tool_use content blocks in API requests and responses
• tool_result content blocks in API requests

When you use tools, we also automatically include a special system prompt for the model which enables tool use. The number of tool use tokens required for each model are listed below (excluding the additional tokens listed above). Note that the table assumes at least 1 tool is provided. If no tools are provided, then a tool choice of none uses 0 additional system prompt tokens.

Model	Tool choice	Tool use system prompt token count
Claude 3.7 Sonnet	auto, none any, tool	346 tokens 313 tokens
Claude 3.5 Sonnet (Oct)	auto, none any, tool	346 tokens 313 tokens
Claude 3 Opus	auto, none any, tool	530 tokens 281 tokens
Claude 3 Sonnet	auto, none any, tool	159 tokens 235 tokens
Claude 3 Haiku	auto, none any, tool	264 tokens 340 tokens
Claude 3.5 Sonnet (June)	auto, none any, tool	294 tokens 261 tokens

These token counts are added to your normal input and output tokens to calculate the total cost of a request.

For current per-model prices, refer to our model pricing section above.

Agent use case pricing examples

Understanding pricing for agent applications is crucial when building with Claude. These real-world examples can help you estimate costs for different agent patterns.

​

Customer support agent example

When building a customer support agent, here’s how costs might break down:

For a detailed walkthrough of this calculation, see our customer support agent guide.

​

General agent workflow pricing

For more complex agent architectures with multiple steps:

1. Initial request processing

   • Typical input: 500-1,000 tokens
   • Processing cost: ~$0.003 per request

2. Memory and context retrieval

   • Retrieved context: 2,000-5,000 tokens
   • Cost per retrieval: ~$0.015 per operation

3. Action planning and execution

   • Planning tokens: 1,000-2,000
   • Execution feedback: 500-1,000
   • Combined cost: ~$0.045 per action

For a comprehensive guide on agent pricing patterns, see our agent use cases guide.

​

Cost optimization strategies

When building agents with Claude:

1. Use appropriate models: Choose Haiku for simple tasks, Sonnet for complex reasoning
2. Implement prompt caching: Reduce costs for repeated context
3. Batch operations: Use the Batch API for non-time-sensitive tasks
4. Monitor usage patterns: Track token consumption to identify optimization opportunities

Additional pricing considerations

​

Rate limits

Rate limits vary by usage tier and affect how many requests you can make:

• Tier 1: Entry-level usage with basic limits
• Tier 2: Increased limits for growing applications
• Tier 3: Higher limits for established applications
• Tier 4: Maximum standard limits
• Enterprise: Custom limits available

For detailed rate limit information, see our rate limits documentation.

​

Volume discounts

Volume discounts may be available for high-volume users. These are negotiated on a case-by-case basis.

• Standard tiers use the pricing shown above
• Enterprise customers can contact sales for custom pricing
• Academic and research discounts may be available

​

Enterprise pricing

For enterprise customers with specific needs:

• Custom rate limits
• Volume discounts
• Dedicated support
• Custom terms

Contact our sales team at sales@anthropic.com or through the Anthropic Console to discuss enterprise pricing options.

​

Billing and payment

• Billing is calculated monthly based on actual usage
• Payments are processed in USD
• Credit card and invoicing options available
• Usage tracking available in the Anthropic Console

​

Frequently asked questions

How is token usage calculated?

Tokens are pieces of text that models process. As a rough estimate, 1 token is approximately 4 characters or 0.75 words in English. The exact count varies by language and content type.

Are there free tiers or trials?

New users receive a small amount of free credits to test the API. Contact sales for information about extended trials for enterprise evaluation.

How do discounts stack?

Batch API and prompt caching discounts can be combined. For example, using both features together provides significant cost savings compared to standard API calls.

What payment methods are accepted?

We accept major credit cards for standard accounts. Enterprise customers can arrange invoicing and other payment methods.
