Firecrawl

Firecrawl provides pay-per-use web scraping, crawling, site mapping, and structured data extraction with built-in JavaScript rendering, anti-bot handling, and proxy rotation. Through the Obul proxy, each request is paid individually — no Firecrawl account or API key required.

Authentication

All requests use the obulx CLI, which handles proxy routing and authentication automatically.

Install and log in (one-time setup):

npm install -g @obul.ai/obulx
obulx login

Base URL: https://firecrawl.x402endpoints.com

Common Operations

Scrape a URL

Scrape a single URL with JavaScript rendering and anti-bot handling. Returns clean markdown by default, with optional HTML, raw HTML, links, and screenshot formats.

Pricing: $0.001

obulx -X POST -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "formats": ["markdown"]}' \
  "https://firecrawl.x402endpoints.com/v1/scrape"

Response: JSON object with scraped content in the requested formats. The markdown format returns clean, well-structured markdown extracted from the page. Additional formats include html, rawHtml, links (list of all URLs on the page), and screenshot (base64-encoded image).

Map a Website

Discover all URLs on a website. Returns a complete sitemap-style list of pages without scraping their content.

Pricing: $0.001

obulx -X POST -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}' \
  "https://firecrawl.x402endpoints.com/v1/map"

Response: JSON object with an array of all discovered URLs on the site. Use this to plan targeted scraping or crawling of specific pages.

Crawl a Website

Start an asynchronous crawl job that scrapes multiple pages on a website. The limit parameter is required and determines both the maximum number of pages crawled and the total cost.

Pricing: $0.001 per page (total = limit × $0.001, max 1000 pages)

obulx -X POST -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "limit": 10}' \
  "https://firecrawl.x402endpoints.com/v1/crawl"

Response: JSON object with a crawl job id and status. The crawl runs asynchronously — use the returned job ID to poll for results. Each crawled page is returned as clean markdown content.

Extract Structured Data

Extract structured data from one or more URLs. Firecrawl scrapes the pages and returns data in a structured format, ideal for pulling specific fields from product pages, articles, or directories.

Pricing: $0.001

obulx -X POST -H "Content-Type: application/json" \
  -d '{"urls": ["https://example.com/product/123"]}' \
  "https://firecrawl.x402endpoints.com/v1/extract"

Response: JSON object with structured data extracted from the provided URLs. The extraction identifies and returns key fields like titles, prices, descriptions, and other structured content from the pages.

Endpoint Pricing Reference

Endpoint	Price	Purpose
POST /v1/scrape	$0.001	Scrape a single URL to clean markdown
POST /v1/map	$0.001	Discover all URLs on a website
POST /v1/crawl	$0.001 per page	Async crawl a website (limit required)
POST /v1/extract	$0.001	Structured data extraction from URLs

When to Use

• Web scraping — Scrape any URL to clean markdown with JavaScript rendering and anti-bot bypass, no browser setup needed.
• Site discovery — Map all URLs on a website before deciding which pages to scrape or crawl.
• Bulk content ingestion — Crawl entire websites or sections to build knowledge bases, datasets, or RAG indexes.
• Structured extraction — Pull specific data fields from product pages, directories, or listings without writing custom parsers.
• AI agent browsing — Give autonomous agents the ability to read and understand web pages at a predictable per-call cost.

Best Practices

• Use map before crawl — Call /v1/map first to discover available URLs, then crawl only the pages you need instead of blindly crawling an entire site.
• Set conservative crawl limits — Start with a small limit (e.g., 10) and increase as needed. The cost scales linearly with the limit, and the maximum is 1000 pages.
• Choose the right format — Default to markdown for most use cases. Use html when you need structure, links when you only need URLs, and screenshot for visual verification.
• Prefer scrape over crawl for single pages — Use /v1/scrape for individual URLs. Only use /v1/crawl when you need multiple pages from the same site.
• Use firecrawl-search for discovery — When you don't have a specific URL, use the firecrawl-search skill (obul-search plugin) to find and scrape pages in one step.

Error Handling

Error	Cause	Solution
402 Payment Required	Payment not processed or insufficient	Verify your account has sufficient balance at my.obul.ai. Run obulx login if not authenticated.
400 Bad Request	Missing or invalid request body	Ensure required fields (url, query, urls, limit) are present and correctly typed.
422 Unprocessable Entity	Valid request but URL cannot be scraped	Verify the URL is accessible and not blocked. Try a different URL or format.
429 Too Many Requests	Rate limit exceeded	Add a short delay between requests and avoid rapid-fire calls.
500 Internal Server Error	Upstream Firecrawl service issue	Wait a few seconds and retry. If persistent, the service may be experiencing downtime.
503 Service Unavailable	Firecrawl service temporarily down	Retry after a brief wait.
