+# R2 API Reference
+
+## PUT (Upload)
+
+```typescript
+// Basic
+await env.MY_BUCKET.put(key, value);
+
+// With metadata
+await env.MY_BUCKET.put(key, value, {
+  httpMetadata: {
+    contentType: 'image/jpeg',
+    contentDisposition: 'attachment; filename="photo.jpg"',
+    cacheControl: 'max-age=3600'
+  },
+  customMetadata: { userId: '123', version: '2' },
+  storageClass: 'Standard', // or 'InfrequentAccess'
+  sha256: arrayBufferOrHex, // Integrity check
+  ssecKey: arrayBuffer32bytes // SSE-C encryption
+});
+
+// Value types: ReadableStream | ArrayBuffer | string | Blob
+```
+
+## GET (Download)
+
+```typescript
+const object = await env.MY_BUCKET.get(key);
+if (!object) return new Response('Not found', { status: 404 });
+
+// Body: arrayBuffer(), text(), json(), blob(), body (ReadableStream)
+
+// Ranged reads
+const object = await env.MY_BUCKET.get(key, { range: { offset: 0, length: 1024 } });
+
+// Conditional GET
+const object = await env.MY_BUCKET.get(key, { onlyIf: { etagMatches: '"abc123"' } });
+```
+
+## HEAD (Metadata Only)
+
+```typescript
+const object = await env.MY_BUCKET.head(key); // Returns R2Object without body
+```
+
+## DELETE
+
+```typescript
+await env.MY_BUCKET.delete(key);
+await env.MY_BUCKET.delete([key1, key2, key3]); // Batch (max 1000)
+```
+## LIST
+
+```typescript
+const listed = await env.MY_BUCKET.list({
+  limit: 1000,
+  prefix: 'photos/',
+  cursor: cursorFromPrevious,
+  delimiter: '/',
+  include: ['httpMetadata', 'customMetadata']
+});
+
+// Pagination (always use truncated flag)
+while (listed.truncated) {
+  const next = await env.MY_BUCKET.list({ cursor: listed.cursor });
+  listed.objects.push(...next.objects);
+  listed.truncated = next.truncated;
+  listed.cursor = next.cursor;
+}
+```
+
+## Multipart Uploads
+
+```typescript
+const multipart = await env.MY_BUCKET.createMultipartUpload(key, {
+  httpMetadata: { contentType: 'video/mp4' }
+});
+
+const uploadedParts: R2UploadedPart[] = [];
+for (let i = 0; i < partCount; i++) {
+  const part = await multipart.uploadPart(i + 1, partData);
+  uploadedParts.push(part);
+}
+
+const object = await multipart.complete(uploadedParts);
+// OR: await multipart.abort();
+
+// Resume
+const multipart = env.MY_BUCKET.resumeMultipartUpload(key, uploadId);
+```
+
+## Presigned URLs (S3 SDK)
+
+```typescript
+import { S3Client, PutObjectCommand } from '@aws-sdk/client-s3';
+import { getSignedUrl } from '@aws-sdk/s3-request-presigner';
+
+const s3 = new S3Client({
+  region: 'auto',
+  endpoint: `https://${accountId}.r2.cloudflarestorage.com`,
+  credentials: { accessKeyId: env.R2_ACCESS_KEY_ID, secretAccessKey: env.R2_SECRET_ACCESS_KEY }
+});
+
+const uploadUrl = await getSignedUrl(s3, new PutObjectCommand({ Bucket: 'my-bucket', Key: key }), { expiresIn: 3600 });
+return Response.json({ uploadUrl });
+```
