Non-custodial paying-fetch client for agents that pay APIs over HTTP 402 (x402, USDC on Base). The operator sets hard per-call/per-day/per-host spend caps, an approval threshold, and allow/deny lists, with an append-only receipt for every attempt; the agent can't raise its own limits. npx -y -p @forum-labs/payfetch payfetch-mcp
