PulpMiner Web Scraper - Convert Any Webpage to Realtime JSON API

Convert any webpage into structured JSON data using AI. Scrape websites, extract data into custom JSON schemas, and call saved APIs programmatically. Useful for web scraping, data extraction, content monitoring, lead generation, price tracking, and building data pipelines.

PulpMiner — AI Web Scraping & JSON API

PulpMiner converts any webpage into structured JSON using AI. You provide a URL and optionally a JSON template, and PulpMiner scrapes the page, runs it through an LLM, and returns clean structured data.

Authentication

All API calls require the apikey header:

apikey: <PULPMINER_API_KEY>

Get your API key from https://pulpminer.com/api — click "Regenerate Key" if you don't have one.

Core Workflow

PulpMiner works in two phases:

1. Create a saved API — Configure a URL, scraper, LLM, and optional JSON template via the PulpMiner dashboard at https://pulpminer.com/api
2. Call the saved API — Use the external endpoint with your API key to fetch structured JSON

Calling a Saved API

Static API (fixed URL)

curl -X GET "https://api.pulpminer.com/external/<apiId>" \
  -H "apikey: <PULPMINER_API_KEY>"

Returns JSON extracted from the configured webpage.

Dynamic API (URL with variables)

For APIs saved with template URLs like https://example.com/search?q={{query}}&page={{page}}:

curl -X POST "https://api.pulpminer.com/external/<apiId>" \
  -H "apikey: <PULPMINER_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"query": "javascript frameworks", "page": "1"}'

The {{variable}} placeholders in the saved URL get replaced with the values you provide.

Response Format

Successful responses return:

{
  "data": { ... },
  "errors": null
}

Error responses return:

{
  "data": null,
  "errors": "Error message describing what went wrong"
}

Caching

• API responses are cached for 24 hours by default
• If cache is older than 15 minutes, PulpMiner serves the cached version while refreshing in the background
• Cache can be disabled per-API in the dashboard settings

Configuration Options (Set in Dashboard)

When creating a saved API at https://pulpminer.com/api, you can configure:

Option	Description
URL	The webpage to scrape
JSON Template	Optional JSON structure for the LLM to follow (e.g., {"name": "", "price": ""})
Render JS	Enable for SPAs and JS-heavy pages (uses headless browser)
CSS Selector	Extract only a specific part of the page (e.g., .product-list, #main-content)
Extra Instructions	Additional guidance for the AI (e.g., "Only extract items with prices above $50")
Dynamic URL	Enable template variables in the URL with {{variable}} syntax
Cache	Toggle response caching on/off

Integration with Zapier

For async scraping in Zapier workflows:

# Static API
curl -X POST "https://api.pulpminer.com/external/zapier/get/<apiId>" \
  -H "apikey: <PULPMINER_API_KEY>" \
  -d '{"callbackURL": "https://hooks.zapier.com/..."}'

# Dynamic API
curl -X POST "https://api.pulpminer.com/external/zapier/post/<apiId>" \
  -H "apikey: <PULPMINER_API_KEY>" \
  -d '{"callbackURL": "https://hooks.zapier.com/...", "query": "value"}'

Returns 201 immediately. Sends scraped data to the callback URL when complete.

Integration with n8n

Verify authentication:

curl -X GET "https://api.pulpminer.com/external/n8n/auth" \
  -H "apikey: <PULPMINER_API_KEY>"

Then use the standard /external/<apiId> endpoints for data fetching.

Credits

• Each API call costs 0.25–0.4 credits depending on the endpoint
• JavaScript rendering adds 0.1 credits extra
• New users get 5 free credits
• Purchase more at https://pulpminer.com/credits

Tips

• Use CSS selectors to narrow down the scraped content and improve accuracy
• Provide a JSON template for consistent, predictable output structures
• Enable JS rendering only when needed — static pages scrape faster and cost fewer credits
• Use extra instructions to guide the AI (e.g., "Return dates in ISO 8601 format")
• For monitoring use cases, keep caching enabled to reduce credit usage
• Use the playground first to verify a URL is scrapable before saving an API config
• Dynamic APIs are ideal for search pages, paginated content, and parameterized URLs
