GET https://dripstack.xyz/api/v1/stock-picks ↗

Paid JSON for stock-picker calls from financial newsletters and investing articles. Query params: optional `date=YYYY-MM-DD` for one UTC effective day, optional `limit`. Default (omit `date`) returns the latest UTC effective day with picks. Rows missing publication timestamps may use extractedAt for the effective day. Returns 404 when no picks exist for the day. USDC `exact` x402 on Base or Solana; amount is based on distinct attributed source posts returned.
