# fetcher.cloud > Pay-per-call HTTP tools that let AI agents do what they can't do alone: > render JavaScript pages in a real browser, extract clean article content, > resolve URL redirect chains, and check domain availability. Paid with the > x402 protocol in USDC on Base or Solana. No accounts, no API keys; every > tool has a free daily tier. ## How to use - Machine-readable manifest of every tool, price, and schema: https://api.fetcher.cloud/ - Human docs: https://api.fetcher.cloud/docs - Payment: x402. The first call returns HTTP 402 with terms; pay in USDC on Base (eip155:8453) or Solana and retry. Works from any tool-using agent (Claude, ChatGPT, Gemini, Grok, Perplexity) or MCP client. ## Tools - [domain](https://api.fetcher.cloud/domain): Real-time domain availability across TLDs via RDAP.
