  -d '{"artifact": { "..." : "..." }, "attestation": { "..." : "..." }}'

Connect a brokerage

Register the user and open a read-only connection portal (Robinhood, Schwab, Coinbase, and more). Requires a Supabase token.

curl -X POST https://www.quantlite.co/v1/connect/snaptrade \
  -H "Authorization: Bearer $TOKEN"
# -> { "connection_id": "...", "redirect_uri": "https://app.snaptrade.com/..." }
