Arch Tools Call 61 AI tools with one key and pay per use in USDC

Arch Tools is an API platform offering 64 AI-powered tools accessible through a single API key with a single POST request each. The tools span web scraping, text generation via Claude, GPT-4, Grok, and Gemini, file conversion, PII detection, crypto price lookups, email sending, and audio transcription. Arch Tools integrates natively with Claude Desktop, Cursor, and Windsurf by adding 6 lines to a configuration file, making all 64 tools available automatically. The platform supports autonomous crypto payments in USDC via the x402 protocol across Base, Ethereum, Arbitrum, Polygon, Solana, and other chains, with Stripe credits as a fallback. Users buy credits once with no monthly fees, and credits are deducted per use. Arch Tools is aimed at developers and AI agent builders who need ready-made utilities without rebuilding common functionality. The tool is available for free to get started.
