Client libraries

Official SDKs handle authentication, submission, polling, cancellation, and file uploads. Use them only in trusted server-side environments.

Python

Synchronous and asynchronous APIs for Python 3.8+.

Node.js and TypeScript

Typed server-side client with automatic polling and retries.

Python

Install

pip install higgsfield-client

Configure credentials

export HF_KEY="your-api-key-id:your-api-key-secret"

Submit and wait

import higgsfield_client

result = higgsfield_client.subscribe(
    "higgsfield-ai/soul/v2/standard",
    arguments={
        "prompt": "Editorial portrait in soft daylight",
    },
)

print(result["images"][0]["url"])

import asyncio

import higgsfield_client


async def main():
    result = await higgsfield_client.subscribe_async(
        "higgsfield-ai/soul/v2/standard",
        arguments={
            "prompt": "Editorial portrait in soft daylight",
        },
    )
    print(result["images"][0]["url"])


asyncio.run(main())

Use submit or submit_async when you need a request controller for explicit polling, status checks, or cancellation. The Python SDK also provides upload, upload_file, and upload_image helpers.

Node.js and TypeScript

Install

npm install @higgsfield/client

Configure credentials

export HF_CREDENTIALS="your-api-key-id:your-api-key-secret"

Submit and wait

import { config, higgsfield } from "@higgsfield/client/v2";

config({
  credentials: process.env.HF_CREDENTIALS,
});

const result = await higgsfield.subscribe(
  "higgsfield-ai/soul/v2/standard",
  {
    input: {
      prompt: "Editorial portrait in soft daylight",
    },
    withPolling: true,
  },
);

if (result.isCompleted) {
  console.log(result.jobs[0].results?.raw.url);
}

The v2 TypeScript client is server-side only and blocks browser use to prevent credential exposure.

Choose an integration style

Requirement	Recommended API
Script or prototype	`subscribe` / `subscribe_async`
Worker with explicit lifecycle control	`submit` / `submit_async`
Existing request ID	`status`, `result`, or `cancel`
Production event-driven integration	Submit with a webhook and keep status polling as recovery

See the Python SDK repository and TypeScript SDK repository for the complete client APIs.
