## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability quantaflow-x402-api-gateway-firecrawl-proxy-e385e688 -d '<json body>'
```

Example prompt: Scrape the page at https://example.com/blog/article-1 and give me its clean text content — use Firecrawl through the QuantaFlow gateway, I'm fine paying the $0.01 USDC per-call fee.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
