# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://signalpulse-peach.vercel.app/api/scan/fantasy?get=trade only — player(s) you would receive&give=trade only — player(s) you would send&mode=start-sit (default) | lineup | waiver | trade&players=candidate pool — names: a-vs-b, comma, or repeated ?player=&scoring=optional — ppr | half-ppr | standard | dfs&slots=optional — how many to start&sport=nfl | mlb | nba | golf … (required)"

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