# API

Last updated Aug 25, 2026|Copy as Markdown|[View as Markdown](https://4f1c5cd2.previews.developers.cloudflare.com/r2/api/index.md)|[Agent setup](https://4f1c5cd2.previews.developers.cloudflare.com/agent-setup/)

R2 provides three API surfaces for interacting with your data:

* **[Workers API](https://4f1c5cd2.previews.developers.cloudflare.com/r2/api/workers/workers-api-reference/):** An in-Worker API accessed by binding an R2 bucket to a [Worker](https://4f1c5cd2.previews.developers.cloudflare.com/workers/). Use the Workers API to read, write, and list objects from within a Worker.
* **[S3-compatible API](https://4f1c5cd2.previews.developers.cloudflare.com/r2/api/s3/api/):** An S3-compatible HTTP API available at `https://<ACCOUNT_ID>.r2.cloudflarestorage.com`. Use existing S3 SDKs and tools to interact with R2.
* **[Cloudflare REST API](https://4f1c5cd2.previews.developers.cloudflare.com/api/resources/r2/):** The `api.cloudflare.com` REST API used by the Cloudflare Dashboard and Wrangler CLI. Supports bucket management and object operations. [Rate limits apply](https://4f1c5cd2.previews.developers.cloudflare.com/r2/platform/limits/#cloudflare-rest-api). Use the S3-compatible API or Workers API for high-throughput workloads.
