xportalx

io.github.virgen101/xportalx

A comprehensive gateway that combines web scraping with blockchain operations, all tied to x402 micropayments on Base. You get the full web data toolkit: fetch APIs, crawl sites, extract structured data, convert to markdown, and even solve captchas. On the crypto side, it wraps DexScreener and Coinbase for price feeds, handles wallet creation through Privy, and executes token swaps via 0x. Most tools cost 0.01 USDC per call, with premium Nansen analytics at 0.99 USDC. The standout is x402_proxy, which lets you pay to access other protected APIs dynamically. Reach for this when you need an AI agent to both gather web data and execute onchain transactions without managing separate services.
