# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://venturepulse-nine.vercel.app/api/startup/due-diligence?focus=legal | financial | technical | all (default: all)&lang=en | es | fr | de | ja | pt | it | nl | ko | zh | ar (default: en)&region=us | eu | uk | apac | global (default: global)&sector=fintech | saas | biotech | ai | climate | consumer | b2b | deeptech | any (default: any)&stage=seed | series-a | series-b | growth (default: seed)"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
