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:

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
