```
## TL;DR
To get structured ZocDoc data via API, use a data API like AlterLab to send a URL and a JSON schema to an extraction endpoint. The API handles browser rendering and anti-bot measures, returning validated, typed JSON data directly.

## Why use ZocDoc data?
Building a data pipeline for healthcare provider information requires high reliability. For data engineers, raw HTML is a liability. Instead, developers use structured data for several high-value use cases:
* **Market Intelligence:** Analyzing provider density and service availability in specific geographic regions.
* **AI Training & RAG:** Feeding verified, structured business information into Large Language Models (LLMs) for healthcare-focused RAG (Retrieval-Augmented Generation) applications.
* **Competitive Analytics:** Monitoring local healthcare trends and provider ratings for market research.
## What data can you extract?
When building a `zocdoc data api` integration, you aren't just looking for text; you are looking for entities. Because ZocDoc is a marketplace, the data is highly structured but often nested within complex DOM trees.
With a schema-based approach, you can reliably extract the following public fields:
* `business_name`: The official name of the clinic or practice.
* `rating`: Numerical rating (e.g., "4.8") and total review count.
* `address`: The full physical location string.
* `phone`: The contact number for the facility.
* `hours`: Operating hours for the specific provider or clinic.
* `category`: The medical specialty (e.g., "Dentist", "Dermatologist").
- **99.2%** — Extraction Accuracy
- **1.4s** — Avg Response Time
- **100%** — Typed JSON Output
## The extraction approach
Traditionally, extracting data from a site like ZocDoc required a heavy stack: a headless browser (Playwright or Puppeteer), a rotating proxy provider, and a complex parser using CSS selectors or XPaths.
The problem is fragility. If ZocDoc changes a single `` class name, your entire pipeline breaks.
A modern data API shifts the complexity from the developer to the infrastructure. Instead of writing parsing logic, you define a schema. The engine handles the heavy lifting:
1. **Rendering:** Executing JavaScript to ensure all content is loaded.
2. **Bypassing:** Managing rotation and anti-bot detection automatically.
3. **Extraction:** Using LLM-powered logic to map raw HTML to your specific JSON requirements.
## Quick start with AlterLab Extract API
To get started, follow our [Getting started guide](/docs/quickstart/installation). Once your environment is set up, you can use the `extract` endpoint to turn any public URL into a JSON object.
### Python Implementation
The Python client allows you to define a schema as a standard dictionary. This ensures the data returned is immediately usable in your application logic.
```python title="extract_zocdoc-com.py" {5-12}
import alterlab
client = alterlab.Client("YOUR_API_KEY")
schema = {
"type": "object",
"properties": {
"business_name": {
"type": "string",
"description": "The business name field"
},
"rating": {
"type": "string",
"description": "The rating field"
},
"address": {
"type": "string",
"description": "The address field"
},
"phone": {
"type": "string",
"description": "The phone field"
},
"hours": {
"type": "string",
"description": "The hours field"
},
"category": {
"type": "string",
"description": "The category field"
}
}
}
result = client.extract(
url="https://zocdoc.com/example-page",
schema=schema,
)
print(result.data)
```
### cURL Implementation
If you are working in a shell environment or via a simple script, use the REST endpoint.
```bash title="Terminal"
curl -X POST https://api.alterlab.io/v1/extract \
-H "X-API-Key: YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"url": "https://zocdoc.com/example-page",
"schema": {"properties": {"business_name": {"type": "string"}, "rating": {"type": "string"}, "address": {"type": "string"}}}
}'
```
1. **Define Schema** —
2. **Call Extract API** —
3. **Receive Typed JSON** —
## Define your schema
The power of the [Extract API docs](/docs/api/extract) lies in the schema validation. You aren't just asking for "the text near the address icon." You are defining a strict type.
When you provide a JSON schema, the engine performs two tasks:
1. **Extraction:** It locates the data within the DOM.
2. **Validation:** It ensures the output matches your types (string, number, boolean, etc.).
If the extraction fails to find a field, it returns `null` rather than breaking your entire parser, allowing your data pipeline to handle missing values gracefully.
## Handle pagination and scale
For large-scale data engineering tasks—such as mapping every provider in a specific zip code—you cannot use synchronous requests. You need to manage concurrency and scale.
### Asynchronous Batching
For high-volume jobs, use the asynchronous pattern. This allows you to submit a batch of URLs and poll for completion, preventing timeout issues in your main application loop.
```python title="batch_zocdoc_extraction.py"
import alterlab
import time
client = alterlab.Client("YOUR_API_KEY")
urls = [
"https://zocdoc.com/provider/1",
"https://zocdoc.com/provider/2",
"https://zocdoc.com/provider/3"
]
# Submit batch for async processing
job = client.extract_batch(
urls=urls,
schema={"type": "object", "properties": {"business_name": {"type": "string"}}}
)
# Poll for results
while not job.is_finished:
print("Processing...")
time.sleep(5)
for result in job.results:
print(result.data)
```
### Managing Costs
When scaling, it is critical to monitor your [AlterLab pricing](/pricing). We offer a transparent cost model. You can use the `estimate_cost` method to preview the expense of a specific extraction before you execute it. This is particularly useful when working with complex schemas that require higher-tier LLM orchestration.
## Key takeaways
* **Stop parsing HTML:** Use a schema-based data API to transform messy web pages into clean JSON.
* **Schema is King:** Defining strict types ensures your downstream pipelines (like SQL databases or AI agents) don't break.
* **Scale with Async:** Use batching and asynchronous jobs for large-scale provider discovery.
* **Automate the Hard Stuff:** Let the engine handle JavaScript rendering and anti-bot measures.

## Frequently Asked Questions
### Is there an official ZocDoc data API?
ZocDoc does not offer a public API for bulk data retrieval. AlterLab provides a data API that enables developers to extract publicly available information into structured JSON formats.
### What ZocDoc data can I extract with AlterLab?
You can extract publicly visible local data such as business name, ratings, addresses, and phone numbers. The Extract API allows you to define a schema to ensure the output is typed and ready for your database.
### How much does ZocDoc data extraction cost?
AlterLab uses a pay-as-you-use model with no monthly minimums. Costs depend on the complexity of the extraction and whether you use a Bring Your Own Key (BYOK) for LLM orchestration.
