#!/usr/bin/env sh
# Install @agent-score/pay — agent-friendly CLI wallet for x402 + MPP payments.
#
# Usage:
#   curl -fsSL https://www.agentscore.com/install-pay.sh | sh
#   curl -fsSL https://raw.githubusercontent.com/agentscore/pay/main/install.sh | sh
#
# Strategy:
#   1. If npm is available, `npm install -g @agent-score/pay` — works everywhere.
#   2. Otherwise, download the prebuilt native binary from the latest GitHub Release
#      to ~/.local/bin/agentscore-pay (no Node runtime required).
