Claude Platform

What is Claude Platform?

Claude Platform is where developers build with Claude through Anthropic's API. The docs organize the API into five areas: model capabilities such as reasoning effort and citations, tools that let Claude act on the web or in your environment, tool infrastructure, context management for long sessions, and files and assets. Alongside the Messages API, which gives direct prompting control for custom agent loops, there is Claude Managed Agents for long-running work on managed infrastructure. Administration and governance are covered by an Admin API, a Usage and Cost API and a Compliance API. Models come in four families (Fable, Opus, Sonnet and Haiku), and the API is also offered through Amazon Bedrock, Claude Platform on AWS, Google Cloud and Microsoft Foundry. Pricing is per million tokens. Claude Haiku 5.5 starts at $0.10 per million input tokens, Sonnet 5.5 is $2 input and $10 output, and batch calls cost 50% less than standard calls.

Use cases

• Add Claude to your own application
• Build tool-using AI agents
• Process large request volumes in batches
• Ground answers in documents with citations
• Cut repeat costs with prompt caching
• Monitor team usage and spend

Who it's for

• Developers
• AI engineers
• Enterprise platform teams

Why use Claude Platform

• Per-token billing means you pay for what an application actually uses, and a model ladder from Haiku to Fable lets you match cost to task difficulty.
• Batch processing at 50% less than standard calls helps with large offline jobs such as classification or extraction.
• Prompt caching rates make repeated long prompts cheaper than sending them fresh each time.
• The same models are reachable through Bedrock, Google Cloud and Microsoft Foundry if your company buys cloud services from one of those vendors.
• Separate Usage and Cost and Admin APIs make it possible to track spend programmatically.

How to get started with Claude Platform

1. Create an account and an API key, setting an expiration and keeping the key out of source control and client-side code.
2. Install an SDK and send a first message through the Messages API to see the request and response shape.
3. Choose a model by comparing capability and cost; the intro suggests Claude Opus 5.5 as a starting point for most workloads.
4. Add tools, citations, caching or batch processing as your application needs them.
5. Monitor usage and cost with the Usage and Cost API and organization admin controls.

Claude Platform limitations

• Feature availability differs between the Claude API and cloud partner platforms
• Some features are in beta and may change or be discontinued
• Batch processing is not Zero Data Retention eligible
• Older models such as Claude Opus 4 and 4.1 are retired outside some cloud providers
