Model Service exposes the platform’s model capabilities as HTTP APIs for external applications to call — built for developers and integration scenarios. It turns model capabilities into programmable interfaces, supporting asynchronous tasks, WebHook callbacks, file uploads, and other HTTP API operations, plus a CLI tool for batch management. Think of it as the service layer that converts “ComfyUI node capabilities → HTTPS API → business systems”.

​
Core Capabilities

​
Use Cases

  • Backend integration: Bring BizyAir’s model capabilities into your own product backend
  • Agent invocation: Let AI agents call models via API to generate images / videos
  • Batch processing: Submit generation tasks in bulk via CLI or scripts
  • Service monetization: Wrap model capabilities into an outward-facing SaaS service

​
Capability Categories

The Model Service APIs are divided into 16 capability categories along the “input → output” dimension.

​
Category Distribution

​
Vendor Distribution

More vendors are being onboarded.
Note: owner=Self denotes a SiliconFlow self-deployed model; owner=Third denotes a third-party channel version. Billing rates may differ.

​
API Model Field Reference

Every API model includes the following core fields:

​
How to Call

​
Direct HTTP Call

  1. Find the target API model on the Model Service page.
  2. Get the endpoint and request body format from the API Reference docs.
  3. Include Authorization: Bearer <token> in the request header (get the token from your personal center).
  4. POST the request; the response returns a requestId for subsequent queries.

​
Async Tasks

  1. Keep the returned requestId after submitting a task.
  2. Poll the task status via the async query interface.
  3. Retrieve the result URL once the task completes.

​
WebHook Callback

  1. Set webhook_url in the request parameters.
  2. Once the task completes, the platform POSTs the callback result to that URL.
  3. Verify the signature server-side, then persist the result.

​
CLI Tool

  1. Install the BizyAir CLI tool.
  2. Log in to your account via bizyair login.
  3. Invoke a model with bizyair run <endpoint> --input <file>.
  4. Query task status with bizyair task get <requestId>.
Note: For detailed API fields, error codes, and CLI commands, see the API Reference, Return Code Reference, and CLI Tool chapters at docs.bizyair.vip.
