Product Pricing Scraper

Use this skill when you need to pull product pricing details from a product page or a small list of product pages and return normalized JSON.

What it extracts

• product title
• current price
• original/list price when available
• currency
• availability / stock text
• product URL
• source hints from JSON-LD, meta tags, and visible DOM selectors

Why this skill exists

Pricing pages are noisy and inconsistent. This skill combines:

1. structured data extraction (JSON-LD)
2. Open Graph / meta tag fallbacks
3. CSS selector fallbacks
4. retry + backoff for temporary failures like 429/5xx

That makes it more reliable than a single-selector scraper.

Inputs

Provide one or more URLs.

Optional knobs:

• --config <path> for selector overrides
• --delay <seconds> to slow requests
• --timeout <seconds> to adjust request timeout

Output

JSON array of normalized pricing records.

  }

• references/notes.md — implementation notes and failure patterns

Good defaults built from prior runs

This skill bakes in lessons from earlier scraping runs:

• back off on 429 and common 5xx responses
• reuse multiple price selectors because ecommerce themes vary widely
• prefer structured product data when present
• keep missing price distinct from request failure
