fotor-sdk 0.1.2

Lightweight async Python SDK for the Fotor OpenAPI

fotor-sdk

Lightweight, async-first Python SDK for the Fotor OpenAPI. Generate images and videos with a single API key -- no MCP server, no S3, no internal services required.

Installation

pip install fotor-sdk

Or install from GitHub:

pip install git+https://github.com/zeng121/fotor-sdk.git

For local development:

git clone https://github.com/zeng121/fotor-sdk.git
cd fotor-sdk
pip install -e .

Quick Start

Single Task

import asyncio
import os
from fotor_sdk import FotorClient, text2image

async def main():
    client = FotorClient(api_key=os.environ["FOTOR_OPENAPI_KEY"])
    result = await text2image(
        client,
        prompt="A diamond kitten on velvet, studio lighting",
        model_id="seedream-4-5-251128",
        resolution="2k",
        aspect_ratio="1:1",
    )
    print(result.result_url)

asyncio.run(main())

Parallel Batch with Progress

import asyncio
import os
from fotor_sdk import FotorClient, TaskRunner, TaskSpec

async def main():
    client = FotorClient(api_key=os.environ["FOTOR_OPENAPI_KEY"])
    runner = TaskRunner(client, max_concurrent=5)

    specs = [
        TaskSpec("text2image", {"prompt": "A cat", "model_id": "seedream-4-5-251128"}, tag="cat"),
        TaskSpec("text2image", {"prompt": "A dog", "model_id": "seedream-4-5-251128"}, tag="dog"),
        TaskSpec("text2video", {"prompt": "Sunset", "model_id": "kling-v3", "duration": 5}, tag="sunset"),
    ]

    def on_progress(total, completed, failed, in_progress, latest):
        print(f"  {completed + failed}/{total} done, latest: {latest.metadata.get('tag')}")

    results = await runner.run(specs, on_progress=on_progress)
    for r in results:
        print(f"{r.metadata.get('tag')}: {r.status.name} -> {r.result_url}")

asyncio.run(main())

Core Classes

FotorClient

FotorClient(
    api_key: str,
    endpoint: str = "https://api.fotor.com",
    poll_interval: float = 2.0,
    max_poll_seconds: float = 1200,
)

Methods:

• await create_task(path, payload) -> task_id
• await get_task_status(task_id) -> TaskResult
• await wait_for_task(task_id) -> TaskResult
• await submit_and_wait(path, payload) -> TaskResult
• submit_and_wait_sync(path, payload) -> TaskResult

TaskRunner

TaskRunner(client: FotorClient, max_concurrent: int = 5)

• await run(specs, on_progress=None) -> list[TaskResult]
• run_sync(specs, on_progress=None) -> list[TaskResult]

TaskResult

TaskResult(task_id, status, result_url, error, elapsed_seconds, metadata)
result.success  # True when COMPLETED with a result_url

TaskSpec

TaskSpec(task_type: str, params: dict, tag: str = "")

Error Handling

from fotor_sdk import FotorAPIError

try:
    result = await text2image(client, prompt="...", model_id="bad-model")
except FotorAPIError as e:
    print(f"API error: {e}  code={e.code}")

For batch runs, failed tasks appear in results with status=FAILED and the error field populated. The runner never raises on individual task failures.
