+
+تكتشف نقطة النهاية `/kickoff` تنسيق الطلب تلقائيًا:

+
+يمكن لمستخدمي API أيضًا تمرير سلاسل URL مباشرة إلى الحقول من نوع الملف — يقوم Pydantic بتحويلها تلقائيًا.
+
+### استخدام API
+
+#### الخيار 1: بدء تشغيل multipart (موصى به)
+
+أرسل الملفات مباشرة مع طلب بدء التشغيل:
+
+```bash
+# With files (multipart) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'inputs={"company_name": "Einstein"}' \
+  -F 'cover_image=@/path/to/photo.jpg'
+```
+
+يتم تخزين الملفات تلقائيًا وتحويلها إلى كائنات `FileInput`. يتلقى الوكيل الملف مع تحسين خاص بالمزود (base64 مضمّن، أو API لرفع الملفات، أو مرجع URL حسب مزود LLM).
+
+#### الخيار 2: بدء تشغيل JSON (بدون ملفات)
+
+```bash
+# Without files (JSON) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}}'
+```
+
+#### الخيار 3: رفع منفصل + بدء تشغيل
+
+هذا بديل لرفع multipart عندما تحتاج إلى رفع الملفات بشكل منفصل عن طلب بدء التشغيل. ارفع الملفات أولاً، ثم أشِر إليها بواسطة URL:
+
+```bash
+# Step 1: Upload
+curl -X POST https://your-deployment.crewai.com/files \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'file=@/path/to/photo.jpg' \

 By providing both unstructured and structured state management options, CrewAI Flows empowers developers to build AI workflows that are both flexible and robust, catering to a wide range of application requirements.
 
+### File Inputs
+
+When using structured state, you can include file-typed fields using classes from `crewai-files`. File-typed fields in your flow state serve as the signal to the Platform—they automatically render as file upload dropzones in the Run tab UI and get populated when files are uploaded via the Platform or passed via `input_files` in the API.
+
+```python
+from crewai.flow.flow import Flow, start
+from crewai_files import File, ImageFile, PDFFile
+from pydantic import BaseModel
+
+class MyState(BaseModel):
+    document: File           # Renders as file dropzone in Platform
+    title: str = ""
+
+class MyFlow(Flow[MyState]):
+    @start()
+    def process(self):
+        # File object is automatically populated in state
+        # when uploaded via Platform UI or passed via API
+        content = self.state.document.read()
+        print(f"Processing {self.state.title}: {len(content)} bytes")
+        return content
+```
+
+When deployed on **CrewAI Platform**, file-typed fields (`File`, `ImageFile`, `PDFFile` from `crewai-files`) automatically render as file upload dropzones in the UI. Users can drag and drop files, which are then populated into your flow's state.
+
+**Kicking off with files via API:**
+
+The `/kickoff` endpoint auto-detects the request format:
+- **JSON body** → normal kickoff
+- **multipart/form-data** → file upload + kickoff
+
+API users can also pass URL strings directly to file-typed fields—Pydantic coerces them automatically.
+
+### API Usage
+
+#### Option 1: Multipart kickoff (recommended)
+
+Send files directly with the kickoff request:
+
+```bash
+# With files (multipart) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'inputs={"company_name": "Einstein"}' \
+  -F 'cover_image=@/path/to/photo.jpg'
+```
+
+Files are automatically stored and converted to `FileInput` objects. The agent receives the file with provider-specific optimization (inline base64, file upload API, or URL reference depending on the LLM provider).
+
+#### Option 2: JSON kickoff (no files)
+
+```bash
+# Without files (JSON) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}}'
+```
+
+#### Option 3: Separate upload + kickoff
+
+This is an alternative to multipart upload when you need to upload files separately from the kickoff request. Upload files first, then reference them by URL:
+
+```bash
+# Step 1: Upload
+curl -X POST https://your-deployment.crewai.com/files \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'file=@/path/to/photo.jpg' \
+  -F 'field_name=cover_image'
+# Returns: {"url": "https://...", "field_name": "cover_image"}
+
+# Step 2: Kickoff with URL
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}, "input_files": {"cover_image": "https://..."}}'
+```
+
+See the Platform API documentation for full `/files` endpoint details.
+
+#### On CrewAI Platform
+
+When using the Platform UI, file-typed fields automatically render as drag-and-drop upload zones. No API calls needed—just drop the file and click Run.
+
 ## Flow Persistence
 
 The @persist decorator enables automatic state persistence in CrewAI Flows, allowing you to maintain flow state across restarts or different workflow executions. This decorator can be applied at either the class level or method level, providing flexibility in how you manage state persistence.

+**CrewAI 플랫폼**에 배포하면 파일 타입 필드(`crewai-files`의 `File`, `ImageFile`, `PDFFile`)가 UI에서 자동으로 파일 업로드 드롭존으로 렌더링됩니다. 사용자는 파일을 드래그 앤 드롭할 수 있으며, 해당 파일은 flow의 상태에 자동으로 채워집니다.
+
+**API를 통한 파일 포함 시작:**
+
+`/kickoff` 엔드포인트는 요청 형식을 자동으로 감지합니다:
+- **JSON body** → 일반 kickoff
+- **multipart/form-data** → 파일 업로드 + kickoff
+
+API 사용자는 파일 타입 필드에 URL 문자열을 직접 전달할 수도 있습니다 — Pydantic이 자동으로 변환합니다.
+
+### API 사용법
+
+#### 옵션 1: Multipart kickoff (권장)
+
+kickoff 요청과 함께 파일을 직접 전송합니다:
+
+```bash
+# With files (multipart) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'inputs={"company_name": "Einstein"}' \
+  -F 'cover_image=@/path/to/photo.jpg'
+```
+
+파일은 자동으로 저장되고 `FileInput` 객체로 변환됩니다. 에이전트는 프로바이더별 최적화(LLM 프로바이더에 따라 인라인 base64, 파일 업로드 API 또는 URL 참조)와 함께 파일을 수신합니다.
+
+#### 옵션 2: JSON kickoff (파일 없음)
+
+```bash
+# Without files (JSON) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}}'
+```
+
+#### 옵션 3: 분리된 업로드 + kickoff
+
+kickoff 요청과 별도로 파일을 업로드해야 할 때 multipart 업로드의 대안입니다. 먼저 파일을 업로드한 다음 URL로 참조합니다:
+
+```bash
+# Step 1: Upload
+curl -X POST https://your-deployment.crewai.com/files \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'file=@/path/to/photo.jpg' \
+  -F 'field_name=cover_image'
+# Returns: {"url": "https://...", "field_name": "cover_image"}
+
+# Step 2: Kickoff with URL
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}, "input_files": {"cover_image": "https://..."}}'
+```
+
+`/files` 엔드포인트에 대한 자세한 내용은 플랫폼 API 문서를 참조하세요.
+
+#### CrewAI 플랫폼에서
+
+플랫폼 UI를 사용할 때 파일 타입 필드는 자동으로 드래그 앤 드롭 업로드 영역으로 렌더링됩니다. API 호출이 필요 없습니다 — 파일을 드롭하고 실행을 클릭하면 됩니다.

+
+Ao usar estado estruturado, você pode incluir campos tipados como arquivo usando classes do `crewai-files`. Campos tipados como arquivo no estado do seu flow servem como sinal para a Plataforma — eles são renderizados automaticamente como zonas de upload de arquivos na aba Run da interface e são preenchidos quando arquivos são enviados via Plataforma ou passados via `input_files` na API.

+
+Quando implantado na **Plataforma CrewAI**, campos tipados como arquivo (`File`, `ImageFile`, `PDFFile` do `crewai-files`) são renderizados automaticamente como zonas de upload de arquivos na interface. Os usuários podem arrastar e soltar arquivos, que são então preenchidos no estado do seu flow.
+
+**Iniciando com arquivos via API:**
+
+O endpoint `/kickoff` detecta automaticamente o formato da requisição:
+- **Corpo JSON** → kickoff normal
+- **multipart/form-data** → upload de arquivo + kickoff
+
+Usuários da API também podem passar strings de URL diretamente para campos tipados como arquivo — o Pydantic as converte automaticamente.
+
+### Uso da API
+
+#### Opção 1: Kickoff multipart (recomendado)
+
+Envie arquivos diretamente com a requisição de kickoff:
+
+```bash
+# With files (multipart) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'inputs={"company_name": "Einstein"}' \
+  -F 'cover_image=@/path/to/photo.jpg'
+```
+
+Os arquivos são armazenados automaticamente e convertidos em objetos `FileInput`. O agente recebe o arquivo com otimização específica do provedor (base64 inline, API de upload de arquivo ou referência por URL dependendo do provedor LLM).
+
+#### Opção 2: Kickoff JSON (sem arquivos)
+
+```bash
+# Without files (JSON) — same endpoint
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}}'
+```
+
+#### Opção 3: Upload separado + kickoff
+
+Esta é uma alternativa ao upload multipart quando você precisa fazer upload dos arquivos separadamente da requisição de kickoff. Faça o upload dos arquivos primeiro e depois referencie-os por URL:
+
+```bash
+# Step 1: Upload
+curl -X POST https://your-deployment.crewai.com/files \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -F 'file=@/path/to/photo.jpg' \
+  -F 'field_name=cover_image'
+# Returns: {"url": "https://...", "field_name": "cover_image"}
+
+# Step 2: Kickoff with URL
+curl -X POST https://your-deployment.crewai.com/kickoff \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -d '{"inputs": {"company_name": "Einstein"}, "input_files": {"cover_image": "https://..."}}'
+```
+
+Consulte a documentação da API da Plataforma para detalhes completos do endpoint `/files`.
+
+#### Na Plataforma CrewAI
+
+Ao usar a interface da Plataforma, campos tipados como arquivo são renderizados automaticamente como zonas de arrastar e soltar para upload. Nenhuma chamada de API é necessária — basta soltar o arquivo e clicar em Executar.

 ## Persistência de Flow
 
 O decorador @persist permite a persistência automática do estado nos flows do CrewAI, garantindo que você mantenha o estado do flow entre reinicializações ou execuções diferentes do workflow. Esse decorador pode ser aplicado tanto ao nível de classe, quanto ao nível de método, oferecendo flexibilidade sobre como gerenciar a persistência do estado.

+
+Se você já tem arquivos hospedados em URLs, passe-os via `input_files`:
