fetcher.cloud — the web capability layer for AI agents
Pay per call in USDC on Base via x402. Every capability has a free daily tier first;
the first unpaid call past that tier returns HTTP 402 with machine-readable terms.
Tip: append ?_forcepay=1 to any path to reach the 402 payment gate without spending
the free tier (useful for monitors and testing).
