REST API Reference

Ultralytics Platform provides a comprehensive REST API for programmatic access to datasets, models, training, and deployments.

!!! tip "Quick Start"

```bash
# List your datasets
curl -H "Authorization: Bearer YOUR_API_KEY" \
  https://platform.ultralytics.com/api/datasets
```

!!! tip "Interactive API Docs"

Explore the full interactive API reference in the [Ultralytics Platform API docs](https://platform.ultralytics.com/api/docs).

API Overview

The API is organized around the core platform resources:

graph LR
    A[API Key] --> B[Datasets]
    A --> C[Projects]
    A --> D[Models]
    A --> E[Deployments]
    B -->|train on| D
    C -->|contains| D
    D -->|deploy to| E
    D -->|export| F[Exports]
    B -->|auto-annotate| B

Resource	Description	Key Operations
Datasets	Labeled image collections	CRUD, images, labels, export, versions, clone
Projects	Training workspaces	CRUD, clone, icon
Models	Trained checkpoints	CRUD, predict, download, clone, export
Deployments	Dedicated inference endpoints	CRUD, start/stop, metrics, logs, health
Exports	Format conversion jobs	Create, status, download
Training	Cloud GPU training jobs	Start, status, cancel
Billing	Credits and subscriptions	Balance, top-up, payment methods
Teams	Workspace collaboration	Members, invites, roles

Authentication

Resource APIs such as datasets, projects, models, training, exports, and predictions use API-key authentication. Public endpoints (listing public datasets, projects, and models) support anonymous read access without a key. Account-oriented routes — including activity, settings, teams, billing, and GDPR flows — currently require an authenticated browser session and are not available via API key.

Get API Key

1. Go to Settings > API Keys
2. Click Create Key
3. Copy the generated key

See API Keys for detailed instructions.

Authorization Header

Include your API key in all requests:

Authorization: Bearer YOUR_API_KEY

!!! info "API Key Format"

API keys use the format `ul_` followed by 40 hex characters. Keep your key secret -- never commit it to version control or share it publicly.

Example

=== "cURL"

```bash
curl -H "Authorization: Bearer YOUR_API_KEY" \
  https://platform.ultralytics.com/api/datasets
```

=== "Python"

```python
import requests

headers = {"Authorization": "Bearer YOUR_API_KEY"}
response = requests.get(
    "https://platform.ultralytics.com/api/datasets",
    headers=headers,
)
data = response.json()
```

=== "JavaScript"

```javascript
const response = await fetch("https://platform.ultralytics.com/api/datasets", {
  headers: { Authorization: "Bearer YOUR_API_KEY" },
});
const data = await response.json();
```

Base URL

All API endpoints use:

https://platform.ultralytics.com/api

Rate Limits

The API enforces per-API-key rate limits (sliding-window, Upstash Redis-backed) to protect against abuse while keeping legitimate usage unrestricted. Anonymous traffic is additionally protected by Vercel's platform-level abuse controls.

When throttled, the API returns 429 with retry metadata:

Retry-After: 12
X-RateLimit-Reset: 2026-02-21T12:34:56.000Z

Per API Key Limits

Rate limits are applied automatically based on the endpoint being called. Expensive operations have tighter limits to prevent abuse, while standard CRUD operations share a generous default:

Endpoint	Limit	Applies To
Default	100 requests/min	All endpoints not listed below (list, get, create, update, delete)
Training	10 requests/min	Starting cloud training jobs (POST /api/training/start)
Upload	10 requests/min	File uploads, signed URLs, and dataset ingest
Predict	20 requests/min	Shared model inference (POST /api/models/{id}/predict)
Export	20 requests/min	Model format exports (POST /api/exports), dataset NDJSON exports, and version creation
Download	30 requests/min	Model weight file downloads (GET /api/models/{id}/download)
Dedicated	Unlimited	Dedicated endpoints — your own service, no API limits

Each category has an independent counter per API key. For example, making 20 predict requests does not affect your 100 request/min default allowance.

Dedicated Endpoints (Unlimited)

Dedicated endpoints are not subject to API key rate limits. When you deploy a model to a dedicated endpoint, requests to that endpoint URL (e.g., https://predict-abc123.run.app/predict) go directly to your dedicated service with no rate limiting from the Platform. You're paying for the compute, so you get throughput from your dedicated service configuration rather than the shared API limits.

!!! tip "Handling Rate Limits"

When you receive a `429` status code, wait for `Retry-After` (or until `X-RateLimit-Reset`) before retrying. See the [rate limit FAQ](#how-do-i-handle-rate-limits) for an exponential backoff implementation.

Response Format

Success Responses

Responses return JSON with resource-specific fields:

!!! note "GPU Types"

Available GPU types include `rtx-4090`, `a100-80gb-pcie`, `a100-80gb-sxm`, `h100-sxm`, `rtx-pro-6000`, and others. See [Cloud Training](../train/cloud-training.md) for the full list with pricing.

Get Training Status

GET /api/models/{modelId}/training

Returns the current training job status, metrics, and progress for a model. Public projects are accessible anonymously; private projects require an active platform browser session (this route does not accept API-key authentication).

Cancel Training

DELETE /api/models/{modelId}/training

Terminates the running compute instance and marks the job as cancelled. Requires an active platform browser session — not available via API key.

---

Deployments API

Deploy models to dedicated inference endpoints with health checks and monitoring. New deployments use scale-to-zero by default, and the API accepts an optional resources object. See Endpoints documentation.

!!! info "API-key support by route"

Only `GET /api/deployments`, `POST /api/deployments`, `GET /api/deployments/{deploymentId}`, and `DELETE /api/deployments/{deploymentId}` support API-key authentication. The `predict`, `health`, `logs`, `metrics`, `start`, and `stop` sub-routes require an active platform browser session — they are convenience proxies for the in-app UI. For programmatic inference, call the deployment's own endpoint URL (e.g., `https://predict-abc123.run.app/predict`) directly with your API key. [Dedicated endpoints](../deploy/endpoints.md#using-endpoints) are not rate-limited.

Field	Type	Required	Description
modelId	string	Yes	Model ID to deploy
name	string	Yes	Deployment name
region	string	Yes	Deployment region
resources	object	No	Resource configuration (cpu, memoryGi, minInstances, maxInstances)

Creates a dedicated inference endpoint in the specified region. The endpoint is globally accessible via a unique URL.

!!! note "Default Resources"

The deployment dialog currently submits fixed defaults of `cpu=1`, `memoryGi=2`, `minInstances=0`, and `maxInstances=1`. The API route accepts a `resources` object, but plan limits cap `minInstances` at `0` and `maxInstances` at `1`.

Python Integration

For easier integration, use the Ultralytics Python package which handles authentication, uploads, and real-time metric streaming automatically.

Installation & Setup

pip install ultralytics

Verify installation:

yolo check

!!! warning "Package Version Requirement"

Platform integration requires **ultralytics>=8.4.35**. Lower versions will NOT work with Platform.

Authentication

=== "CLI (Recommended)"

```bash
yolo settings api_key=YOUR_API_KEY
```

=== "Environment Variable"

```bash
export ULTRALYTICS_API_KEY=YOUR_API_KEY
```

=== "In Code"

```python
from ultralytics import settings

settings.api_key = "YOUR_API_KEY"
```

Using Platform Datasets

Reference datasets with ul:// URIs:

from ultralytics import YOLO

model = YOLO("yolo26n.pt")

# Train on your Platform dataset
model.train(
    data="ul://your-username/datasets/your-dataset",
    epochs=100,
    imgsz=640,
)

URI Format:

Pattern	Description
ul://username/datasets/slug	Dataset
ul://username/project-name	Project
ul://username/project/model-name	Specific model
ul://ultralytics/yolo26/yolo26n	Official model

Pushing to Platform

Send results to a Platform project:

from ultralytics import YOLO

model = YOLO("yolo26n.pt")

# Results automatically sync to Platform
model.train(
    data="coco8.yaml",
    epochs=100,
    project="your-username/my-project",
    name="experiment-1",
)

What syncs:

• Training metrics (real-time)
• Final model weights
• Validation plots
• Console output
• System metrics

API Examples

Load a model from Platform:

# Your own model
model = YOLO("ul://username/project/model-name")

# Official model
model = YOLO("ul://ultralytics/yolo26/yolo26n")

Run inference:

results = model("image.jpg")

# Access results
for r in results:
    boxes = r.boxes  # Detection boxes
    masks = r.masks  # Segmentation masks
    keypoints = r.keypoints  # Pose keypoints
    probs = r.probs  # Classification probabilities

Export model:

# Export to ONNX
model.export(format="onnx", imgsz=640, half=True)

# Export to TensorRT
model.export(format="engine", imgsz=640, half=True)

# Export to CoreML
model.export(format="coreml", imgsz=640)

Validation:

metrics = model.val(data="ul://username/datasets/my-dataset")

print(f"mAP50: {metrics.box.map50}")
print(f"mAP50-95: {metrics.box.map}")

---

Webhooks

The Platform uses internal webhooks to stream real-time training metrics from the ultralytics Python SDK (running on cloud GPUs or remote/local machines) back to the Platform — epoch-by-epoch loss, mAP, system stats, and completion status. These webhooks are authenticated via the HMAC webhookSecret provisioned per training job and are not intended to be consumed by user applications.

!!! info "Working on your side"

**All plans**: Training progress via the `ultralytics` SDK (real-time metrics, completion notifications) works automatically on every plan — just set `project=username/my-project name=my-run` when training and the SDK streams events back to the Platform. No user-side webhook registration is required.

**User-facing webhook subscriptions** (POST callbacks to a URL you control) are on the Enterprise roadmap and not currently available. In the meantime, poll `GET /api/models/{modelId}/training` for status or use the [activity feed](#activity-api) in the UI.

---

FAQ

How do I paginate large results?

Most endpoints use a limit parameter to control how many results are returned per request:

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://platform.ultralytics.com/api/datasets?limit=50"

The Activity and Trash endpoints also support a page parameter for page-based pagination:

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://platform.ultralytics.com/api/activity?page=2&limit=20"

The Explore Search endpoint uses offset instead of page, with a fixed page size of 20:

curl "https://platform.ultralytics.com/api/explore/search?type=datasets&offset=20&sort=stars"

Can I use the API without an SDK?

Yes, all functionality is available via REST. The Python SDK is a convenience wrapper that adds features like real-time metric streaming and automatic model uploads. You can also explore all endpoints interactively at platform.ultralytics.com/api/docs.

Are there API client libraries?

Currently, use the Ultralytics Python package or make direct HTTP requests. Official client libraries for other languages are planned.

How do I handle rate limits?

Use the Retry-After header from the 429 response to wait the right amount of time:

import time

import requests


def api_request_with_retry(url, headers, max_retries=3):
    for attempt in range(max_retries):
        response = requests.get(url, headers=headers)
        if response.status_code != 429:
            return response
        wait = int(response.headers.get("Retry-After", 2**attempt))
        time.sleep(wait)
    raise Exception("Rate limit exceeded")

How do I find my model or dataset ID?

Resource IDs are returned when you create resources via the API. You can also find them in the platform URL:

https://platform.ultralytics.com/username/project/model-name
                                  ^^^^^^^^ ^^^^^^^ ^^^^^^^^^^
                                  username project   model

Use the list endpoints to search by name or filter by project.
