Claude API — Developer API
The surface that carries the server-side tools: browser control, desktop control, sandboxed code execution, web search with citations, batching and prompt caching.

What you can do with it
- Run Anthropic-executed tools inside a turn, so search and code execution do not need a client-side loop.
- Cut repeat-context cost to a tenth with prompt caching, and bulk work to half price with the Batches API.
- Read PDFs up to 32 MB and 600 pages, and images up to 8000x8000 px, by file reference rather than base64.
- Run Agent Skills inside the code execution container by skill_id.
