```
## TL;DR
To get structured TechCrunch data via API, send a POST request to AlterLab's Extract API containing the target URL and a JSON schema defining your required fields. The engine handles proxy rotation and anti-bot bypass, returning validated, typed JSON instead of raw HTML.

## Why use TechCrunch data?
Building a specialized tech intelligence pipeline requires reliable, structured data. Relying on raw HTML is a recipe for broken pipelines when site layouts change. Engineers typically integrate TechCrunch data for:
* **AI Training & RAG**: Feed high-signal tech news into LLMs for Retrieval-Augmented Generation.
* **Market Intelligence**: Monitor startup funding rounds and M&A activity in real-time.
* **Automated News Aggregators**: Build custom dashboards that track specific technology trends or keywords.
## What data can you extract?
When building a tech intelligence tool, you don't need the entire DOM. You need specific, actionable fields. Using a data API allows you to define exactly what your schema requires. Common fields extracted from TechCrunch include:
* **title**: The headline of the article.
* **author**: The journalist or contributor name.
* **published_date**: The timestamp of publication in a standardized format.
* **tags**: The categories associated with the story (e.g., "Startup", "Venture Capital").
* **url**: The canonical link to the article.
- **99.2%** — Extraction Accuracy
- **1.4s** — Avg Response Time
- **100%** — Typed JSON Output
## The extraction approach
The traditional approach to web data extraction involves fetching HTML via an HTTP client and then using CSS selectors or XPath to parse the content. This method is fragile. If TechCrunch updates a single `` class name, your parser breaks.
A modern data API treats the web as a structured source. Instead of writing complex parsing logic, you define a schema. The engine handles the heavy lifting: navigating the DOM, managing rotating proxies, and bypassing sophisticated anti-bot measures. This shifts your workload from "maintaining scrapers" to "consuming data."
To get started with this approach, refer to our [Getting started guide](/docs/quickstart/installation).
## Quick start with AlterLab Extract API
The AlterLab Extract API uses a schema-driven model. You provide the URL and a JSON schema, and the engine returns the data matching that schema.
### Python Implementation
The Python SDK makes it trivial to integrate extraction into your existing data pipelines.
```python title="extract_techcrunch-com.py" {5-12}
import alterlab
client = alterlab.Client("YOUR_API_KEY")
schema = {
"type": "object",
"properties": {
"title": {
"type": "string",
"description": "The headline of the article"
},
"author": {
"type": "string",
"description": "The name of the author"
},
"published_date": {
"type": "string",
"description": "The date the article was published"
},
"tags": {
"type": "array",
"items": {"type": "string"},
"description": "List of article tags"
},
"url": {
"type": "string",
"description": "The URL of the article"
}
}
}
result = client.extract(
url="https://techcrunch.com/example-article/",
schema=schema,
)
print(result.data)
```
### cURL Implementation
If you are working in a shell environment or a lightweight microservice, use a simple POST request.
```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://techcrunch.com/example-article/",
"schema": {
"type": "object",
"properties": {
"title": {"type": "string"},
"author": {"type": "string"},
"published_date": {"type": "string"}
}
}
}'
```
## Define your schema
The core strength of the Extract API is validation. Because you provide a JSON schema, the output is guaranteed to match your expected types. This eliminates the "null pointer" errors common in traditional scraping when a field is missing or a class name changes.
The engine uses LLM-powered extraction to map the visual elements of a page to your schema. This is why it works even when the underlying HTML structure is complex or obfuscated.
1. **Define Schema** —
2. **Call Extract API** —
3. **Receive Typed JSON** —
## Handle pagination and scale
For high-volume data pipelines—such as indexing an entire category of TechCrunch news—you shouldn't rely on sequential requests. You need to manage scale and cost efficiently.
### Batching and Async Jobs
When processing thousands of URLs, use asynchronous job patterns. Instead of waiting for a single request to finish, submit a batch of URLs and poll for results or use [Webhooks](/docs/api/webhooks) to receive data as it is ready.
### Cost Management
Managing your spend is critical for production pipelines. You can use the [Extract API docs](/docs/api/extract) to learn about the `estimate` endpoint, which allows you to calculate the cost of a request before committing to it.
* **Cost estimation**: Always check the estimated cost to prevent unexpected spikes in your balance.
* **Scaling**: For large-scale operations, keep an eye on your [AlterLab pricing](/pricing) to optimize your workflow.
```python title="batch_extraction.py" {1-6}
import alterlab
import asyncio
client = alterlab.Client("YOUR_API_KEY")
urls = [
"https://techcrunch.com/article-1/",
"https://techcrunch.com/article-2/",
"https://techcrunch.com/article-3/"
]
async def fetch_data(url):
# Using async calls for high-concurrency pipelines
return await client.extract_async(url=url, schema=my_schema)
async def main():
results = await asyncio.gather(*(fetch_data(u) for u in urls))
for r in results:
print(r.data)
asyncio.run(main())
```
## Key takeaways
* **Stop parsing HTML**: Use a data API to convert websites into structured JSON via schema definitions.
* **Schema-driven extraction**: Use JSON Schema to ensure your data pipelines receive typed, predictable output.
* **Scale efficiently**: Use async patterns and webhooks to handle high-volume tech data extraction.
* **Predictable costs**: Use the estimation endpoint to manage your balance and optimize your pipeline spend.
## Frequently Asked Questions
### Is there an official TechCrunch data API?
TechCrunch does not offer a public, self-service API for high-volume data extraction. AlterLab fills this gap by providing a data API that converts public HTML into structured JSON.
### What TechCrunch data can I extract with AlterLab?
You can extract any publicly visible information, such as article titles, author names, publication dates, and tags, directly into a typed JSON schema.
### How much does TechCrunch data extraction cost?
AlterLab uses a pay-as-you-go model via a balance system, allowing you to pay only for the data you retrieve with no minimum commitment.
