TL;DR

Extract publicly listed Binance data with a single POST to the AlterLab Extract API, providing a JSON schema that defines ticker, price, change_percent, volume, and market_cap; the service returns validated JSON and includes a cost preview before execution.

This guide covers extracting publicly accessible data. Always review a site's robots.txt and Terms of Service before scraping.

Why use Binance data?

Practical use cases include AI training on market signals, real‑time analytics for dashboards, and competitive intelligence on price movements. The data is openly displayed on pages such as ticker listings and can be integrated into pipelines without manual parsing.

What data can you extract?

Publicly available finance fields often include:

• ticker: the symbol identifier
• price: current market price
• change_percent: percent change over the last 24 hours
• volume: trading volume
• market_cap: calculated market capitalization

These fields appear in HTML elements that are stable for extraction when using a structured approach.

The extraction approach

Raw HTTP requests followed by HTML parsing are fragile; site layout changes can break selectors. A data API sits between you and the target page, handling rendering, anti‑bot bypass, and output validation. AlterLab provides a hosted endpoint that accepts a URL and a schema, then returns typed JSON. This reduces maintenance overhead and ensures compliance with rate limits and request formatting.

Quick start with AlterLab Extract API

See the Getting started guide for installation details. The following Python snippet shows a minimal extract call.

from alterlab import AlterLabSync

client = AlterLabSync("YOUR_API_KEY")

schema = {
  "type": "object",
  "properties": {
    "ticker": {
      "type": "string",
      "description": "The ticker field"
    },
    "price": {
      "type": "string",
      "description": "The price field"
    },
    "change_percent": {
      "type": "string",
      "description": "The change percent field"
    },
    "volume": {
      "type": "string",
      "description": "The volume field"
    },
    "market_cap": {
      "type": "string",
      "description": "The market cap field"
    }
  }
}

result = client.scrape(
    url="https://binance.com/example-page",
    extraction_schema=schema,
)
print(result["filtered_content"])

The equivalent cURL request is:

curl -X POST https://api.alterlab.io/v1/extract \
  -H "X-API-Key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://binance.com/example-page",
    "schema": {"properties": {"ticker": {"type": "string"}, "price": {"type": "string"}, "change_percent": {"type": "string"}}}
  }'

Both examples include a cost preview; the endpoint returns an estimate before the full extraction runs. See AlterLab pricing for detailed rate information.

Define your schema

The schema parameter validates the output structure. Fields are declared with type and description; the API enforces the shape and rejects mismatched payloads. You can extend the schema with nested objects or arrays to match more complex page structures.

Handle pagination and scale

When collecting data across multiple pages, batch requests and respect rate limits. The API supports asynchronous job submission for high‑volume workloads; you can poll for completion and retrieve results once ready. This pattern scales to thousands of pages while keeping per‑request cost predictable.

Key takeaways

• Use a data API to safely retrieve structured Binance data.
• Provide a clear schema to get typed JSON output.
• Preview cost before committing to
