EyePop.ai Python SDK

Python SDK for EyePop.ai's inference and data APIs.

pip install eyepop

Requires Python 3.12+.

Quickstart

from eyepop import EyePopSdk

with EyePopSdk.sync_worker() as endpoint:
    result = endpoint.upload('photo.jpg').predict()
    print(result)

Set EYEPOP_API_KEY in your environment (get one at dashboard.eyepop.ai), or pass api_key=... to sync_worker():

endpoint = EyePopSdk.sync_worker(api_key='my-api-key', pop_id='my-pop-id')

Configuration

Credentials are read from environment variables. Set one auth method:

Variable	Description
`EYEPOP_API_KEY`	API key from your dashboard.
`EYEPOP_ACCESS_TOKEN`	Pre-issued OAuth access token.

Optional:

Variable	Description
`EYEPOP_POP_ID`	Named pop ID. Defaults to `transient`.
`EYEPOP_ACCOUNT_ID`	Required for some Data API calls.

Usage

Single image

from eyepop import EyePopSdk

with EyePopSdk.sync_worker() as endpoint:
    result = endpoint.upload('photo.jpg').predict()
    print(result)

upload() queues the file; predict() blocks until the result is ready. For videos or multi-frame containers, call predict() in a loop until it returns None.

Binary streams

with EyePopSdk.sync_worker() as endpoint:
    with open('photo.jpg', 'rb') as file:
        result = endpoint.upload_stream(file, 'image/jpeg').predict()

URLs (HTTP, RTSP, RTMP)

with EyePopSdk.sync_worker() as endpoint:
    result = endpoint.load_from('https://example.com/image.jpg').predict()

Videos

with EyePopSdk.sync_worker() as endpoint:
    job = endpoint.load_from('https://example.com/video.mp4')
    while result := job.predict():
        print(result)

Cancel a job mid-stream with job.cancel().

Image groups (multiple images, one result)

Send several images as a single source that the pop processes together as one inference unit — for example a multi-image VLM prompt. The group yields one prediction for the whole set, unlike Batching below, where each image is an independent inference.

with EyePopSdk.sync_worker() as endpoint:
    # local files
    result = endpoint.upload_group(['a.jpg', 'b.jpg', 'c.jpg']).predict()

    # in-memory streams (optional parallel content types)
    with open('a.jpg', 'rb') as a, open('b.jpg', 'rb') as b:
        result = endpoint.upload_stream_group([a, b]).predict()

    # remote URLs (the server fetches each)
    result = endpoint.load_from_group([
        'https://example.com/a.jpg',
        'https://example.com/b.jpg',
    ]).predict()

Image order is preserved end-to-end. A group may contain up to 16 images (enforced server-side). The pop's ability must be multi-image-capable; a single-image ability handed a group returns an error.

Batching

Queue multiple uploads, then collect results:

file_paths = ['photo1.jpg', 'photo2.jpg']

with EyePopSdk.sync_worker() as endpoint:
    jobs = [endpoint.upload(p) for p in file_paths]
    for job in jobs:
        print(job.predict())

Async with callbacks

import asyncio
from eyepop import EyePopSdk, Job

async def main(paths):
    async def on_ready(job: Job):
        print(await job.predict())

    async with EyePopSdk.async_worker() as endpoint:
        for p in paths:
            await endpoint.upload(p, on_ready=on_ready)

asyncio.run(main(['photo1.jpg', 'photo2.jpg']))

Visualize results

from PIL import Image
import matplotlib.pyplot as plt
from eyepop import EyePopSdk

with EyePopSdk.sync_worker() as endpoint:
    result = endpoint.upload('photo.jpg').predict()

with Image.open('photo.jpg') as image:
    plt.imshow(image)
EyePopSdk.plot(plt.gca()).prediction(result)
plt.show()

Composable Pops

Build multi-stage inference pipelines by chaining models. Configure at runtime with endpoint.set_pop(pop).

Components

Component	Purpose
`InferenceComponent`	Run a model. Supports chunked video via `videoChunkLengthSeconds` / `videoChunkOverlap`.
`TrackingComponent`	Track detected objects across frames.
`ContourFinderComponent`	Extract contours from segmentation masks.
`ComponentFinderComponent`	Extract connected components from masks.
`ForwardComponent`	Route outputs between stages.

Forwarding

CropForward — pass each detection crop to sub-components.
FullForward — pass the full image to sub-components.

Both accept includeClasses to filter forwarded detections.

Example: Vehicle → License Plate → OCR

from eyepop.worker.worker_types import (
    Pop, InferenceComponent, TrackingComponent, CropForward, MotionModel,
)

pop = Pop(components=[
    InferenceComponent(
        ability='eyepop.vehicle:latest',
        categoryName='vehicles',
        confidenceThreshold=0.8,
        forward=CropForward(targets=[
            TrackingComponent(
                maxAgeSeconds=5.0,
                motionModel=MotionModel.CONSTANT_VELOCITY,
                agnostic=True,
            ),
            InferenceComponent(
                ability='eyepop.vehicle.license-plate:latest',
                topK=1,
                forward=CropForward(targets=[
                    InferenceComponent(
                        ability='eyepop.text.recognize.landscape:latest',
                        categoryName='license-plate',
                    ),
                ]),
            ),
        ]),
    ),
])

Example: VLM open-vocabulary detection

from eyepop.worker.worker_types import Pop, InferenceComponent, CropForward

pop = Pop(components=[
    InferenceComponent(
        ability='eyepop.localize-objects:latest',
        params={'prompts': [{'prompt': 'person'}]},
        forward=CropForward(targets=[
            InferenceComponent(
                ability='eyepop.image-contents:latest',
                params={'prompts': [{'prompt': 'hair color?'}]},
            ),
        ]),
    ),
])

Data Endpoint

Dataset management, VLM inference, and evaluation workflows.

import asyncio
from eyepop import EyePopSdk

async def main():
    async with EyePopSdk.dataEndpoint(is_async=True) as endpoint:
        datasets = await endpoint.list_datasets()
        print(datasets)

asyncio.run(main())

VLM inference on a single asset

from eyepop.data.data_types import InferRequest, TranscodeMode

async with EyePopSdk.dataEndpoint(is_async=True) as endpoint:
    job = await endpoint.infer_asset(
        asset_uuid='your-asset-uuid',
        infer_request=InferRequest(text_prompt='Describe this image.'),
        transcode_mode=TranscodeMode.image_cover_1024,
    )
    while result := await job.predict():
        print(result)

Batch dataset evaluation

from eyepop.data.data_types import EvaluateRequest, InferRequest

request = EvaluateRequest(
    dataset_uuid='your-dataset-uuid',
    infer=InferRequest(text_prompt='How many people are in this image?'),
)

async with EyePopSdk.dataEndpoint(is_async=True, job_queue_length=4) as endpoint:
    job = await endpoint.evaluate_dataset(evaluate_request=request)
    response = await job.response
    print(response.model_dump_json(indent=2))
