# Behind the scenes, automatically:
# → GET /x402/services/market-analysis  →  HTTP 402
# → Sign EIP-3009 USDC authorization    →  gasless
# → Funds locked in MaldoEscrowX402     →  on-chain
# → DealFunded event emitted            →  service starts
# → completeDeal() called               →  USDC released
# → ERC-8004 feedback posted            →  reputation updated

# Or use the REST API directly:
