Every institution in the catalog, one page each.

FeelConnect does not hold bank connections of its own. Every institution in the catalog carries an ordered chain of connectors, and live traffic goes to the first one whose credentials are present in the deployment you are calling.

Some connectors an operator can switch on alone in minutes — GoCardless Bank Account Data (UK and EU banks, free self-signup under their PSD2 licence), Coinbase, Kraken, PayPal, public-address crypto wallets, and CSV / OFX / QFX import. Others need a signed business relationship before they will serve production data, including Plaid, MX, Finicity, Akoya, and Stripe Financial Connections. Where an institution has no enabled connector, a live call returns provider_error rather than pretending.

The sandbox is the exception and it is always on: test keys resolve to the simulated network regardless of credentials, so the full integration is buildable on day one. See going live for the provider-by-provider breakdown.
