Does APIYI Support the Files API?

APIYI does not provide the Files API, nor the Batch, Assistants, and similar APIs that depend on it. Calling /v1/files returns “Current group … has no available channels for model”. Send images, PDFs, and other files directly in the request as base64 or a URL.

Short Answer

No. APIYI does not provide the Files API, meaning the flow where you upload a file first, get a file_id, and then reference it in a request. The APIs that depend on file uploads are not provided either:

API	Path	Result
OpenAI Files API	/v1/files	503, “no available channels” for the current group
OpenAI Assistants API	/v1/assistants, /v1/threads	503, same as above
OpenAI Batch API	/v1/batches	404 Invalid URL
OpenAI Vector Stores, Uploads	/v1/vector_stores, /v1/uploads	404 Invalid URL
Claude Message Batches	/v1/messages/batches	404 Invalid URL
Gemini Files API	client.files.upload(), /v1beta/files	Not available

What to do instead: put images, PDFs, and other files directly into the chat request as base64 or a URL. Every provider’s models support this inline style; see below.

What the Error Means

Calling /v1/files returns:

{
  "error": {
    "message": "Current group default has no available channels for model  under billing mode [pay-as-you-go, pay-per-request] (request id: …)",
    "type": "shell_api_error"
  }
}

Note that nothing follows for model. The platform routes each request to a channel by model name. A file upload request carries no model name, so the platform finds no matching channel and returns this error. What it really means is that the platform does not provide this API. It has nothing to do with your group, balance, or token permissions, and switching groups or retrying will not help.

If you reference a file_id in a chat request, the error depends on the endpoint, for example:

Usage	Error
file.file_id in /v1/chat/completions	Files [file-xxx] were not found
input_file.file_id in /v1/responses	Invalid 'input[0].content[0].file_id'

If you use the official OpenAI, Anthropic, or Google SDK with base_url pointed at APIYI, methods such as client.files.create(), client.files.upload(), and client.batches.create() will fail. Switch to the inline style below.

Alternative: Put the File Directly in the Request

OpenAI format

Images: pass a public URL or data:image/png;base64,... in image_url.

PDF: in /v1/responses, use file_data on input_file; in /v1/chat/completions, use file_data on the file type.

{
  "model": "gpt-5.4-mini",
  "input": [{
    "role": "user",
    "content": [
      {
        "type": "input_file",
        "filename": "report.pdf",
        "file_data": "data:application/pdf;base64,JVBERi0xLjQK..."
      },
      { "type": "input_text", "text": "Summarize this file" }
    ]
  }]
}

Claude format

Images: an image block with source.type set to base64 or url.

PDF: a document block with source.type set to base64. source.type = "file" depends on the Files API and is not available.

{
  "model": "claude-haiku-4-5-20251001",
  "max_tokens": 1024,
  "messages": [{
    "role": "user",
    "content": [
      {
        "type": "document",
        "source": {
          "type": "base64",
          "media_type": "application/pdf",
          "data": "JVBERi0xLjQK..."
        }
      },
      { "type": "text", "text": "Summarize this file" }
    ]
  }]
}

Gemini format

Images, PDFs, audio and video: pass base64 in inline_data, up to 20MB per file. Images can also be passed as a public URL in file_data.file_uri.

{
  "contents": [{
    "role": "user",
    "parts": [
      {
        "inline_data": {
          "mime_type": "application/pdf",
          "data": "JVBERi0xLjQK..."
        }
      },
      { "text": "Summarize this file" }
    ]
  }]
}

For large videos, see Video Understanding API.

All three styles were tested on 2026-10-22: the same PDF was sent through /v1/responses, /v1/chat/completions, Claude /v1/messages, and Gemini generateContent, and the model read the file content correctly every time.

The cost of the inline style is that every request carries the file again, so request bodies get larger. If you ask many questions about the same file, convert it to text and put that in the prompt, or use each provider’s caching to reduce the cost of repeated input; see Does APIYI Support Cache Billing?.

What About Batch Processing?

There is no Batch API. For batch jobs, send ordinary requests concurrently from your client; for concurrency limits see What Are the API Concurrency Limits?. Ordinary requests are billed at normal prices, without the asynchronous discount of the official Batch API.
