SparkForge — 20+ Utility APIs with x402 Micropayments
henry-ships/sparkforge
This is a pay-per-use API aggregator that bundles 20+ utility endpoints into a single MCP interface. You get image generation, cryptocurrency data, email verification, SSL certificate checking, and web scraping without managing multiple API keys or integrations. The pay-per-use model means you're not locked into monthly subscriptions for services you might only need occasionally. Reach for this when you need ad-hoc access to common API functions without the overhead of setting up individual providers. It uses streamable HTTP transport and connects via sparkforge.sh/mcp, though the source repository only contains Next.js boilerplate without implementation details.
