# 1. Install
pnpm install
pnpm -r build

# 2. Generate a payer wallet, fund it on devnet
node packages/cli/dist/index.js wallet new
node packages/cli/dist/index.js wallet show
# → fund SOL at https://faucet.solana.com  (paste pubkey)
# → fund USDC at https://faucet.circle.com (Solana Devnet, same pubkey)

# 3. (option A — fastest) Use our hosted devnet facilitator. Skip step 4.
export FACILITATOR_URL=https://agentpay-facilitator-e9b20a5fee6a.herokuapp.com

# 3. (option B — fully self-hosted) Start your own facilitator (terminal 1)
pnpm --filter @agenticpay/facilitator dev
# Note the printed feePayer address. It needs ~0.05 SOL devnet to cover fees.
# Either airdrop or use the helper:
pnpm --filter @agenticpay/facilitator fund
export FACILITATOR_URL=http://localhost:4022

# 4. Start the paywalled mcp-server (terminal 2)
PAY_TO=<recipient pubkey> pnpm --filter @agenticpay/mcp-server dev

# 5. Run the live LLM agent demo (terminal 3, needs ANTHROPIC_API_KEY in .env)
