REST API Access

Every tool on Healthcare Online Tools is powered by a shared core library. The same algorithms that run in your browser are available through a clean, versioned REST API — ready to plug into your backend, scripts, or automation pipelines.

Versioned Endpoints

Stable /api/v1/ routes with backwards-compatible updates.

JSON In, JSON Out

Simple request/response format. No SDKs required — use curl, fetch, or any HTTP client.

File Processing

Upload files via multipart/form-data. Get processed results as downloadable responses or JSON metadata.

Batch Operations

Process multiple inputs in a single request for high-throughput workflows.

Example Request 
curl -X POST https://api.healthcareonlinetools.com/v1/tools/text/word-count \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello world"}'

Frequently Asked Questions

Is there a free tier for the API?

The browser-based tools on this website are free. API access and on-premise deployment are paid services with plans tailored to your usage.

What authentication does the API use?

API keys with optional OAuth 2.0 for enterprise integrations. All requests are authenticated and rate-limited per your plan.

Can I try the API before committing?

Yes. Contact us to request a trial API key with limited quota so you can evaluate the integration.

What happens to my data?

Cloud API requests are processed in memory and never stored. On-premise deployments give you full control — data never leaves your infrastructure.

Do you offer white-label licensing?

Yes. Enterprise plans include white-label options for embedding our tools into your own product or platform.

How often is the API updated?

The API shares the same core library as the website. Updates are continuous, with versioned endpoints ensuring backwards compatibility.
