# No account or API key — your wallet is your identity. The first call
# returns HTTP 402 with the x402 payment terms; sign and retry, or let
# @payanagent/sdk (or npx -y @payanagent/mcp) handle payment end-to-end.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
