How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Firecrawl API response is passed through transparently after payment succeeds — typically includes scraped page content (markdown, HTML, or structured data), metadata, and status information as returned by Firecrawl.
Example use cases
Extract article text for LLM ingestion
“Fetch the full text from https://techcrunch.com/2025/01/15/ai-roundup/ using Firecrawl so I can feed it into my summarization pipeline — it's a POST to the /scrape path with that URL in the body.”
Crawl product page for price monitoring
“Use Firecrawl via QuantaFlow to scrape https://shop.example.com/products/widget-pro and pull out the price and availability — send a POST to the scrape endpoint with that URL.”
Extract markdown from documentation site
“I need the markdown version of https://docs.myproject.io/getting-started — can you call Firecrawl through QuantaFlow to scrape it and return the formatted content?”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/firecrawl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use access to Firecrawl's web scraping capabilities without managing a Firecrawl API key subscription, especially in web3/DeFi agent workflows that already handle x402 micropayments in USDC. Ideal for low-volume or sporadic scraping needs where a per-call $0.01 cost is preferable to a monthly subscription.
Side effects
- Payment failure: insufficient USDC balance or x402 payment header missing/invalid — returns 402 Payment Required
- Invalid path: unrecognized Firecrawl endpoint path — upstream 404 or error
- Malformed body: invalid JSON in the body field — upstream parse error or 400
- Upstream Firecrawl error: target URL unreachable, rate-limited, or blocked — passes through Firecrawl error response
- Network timeout: Vercel function timeout if upstream takes too long
