Enable Banking vs Plaid

Enable Banking

Restricted mode gives live data for your own whitelisted accounts before any contract. No public prices and a minimum monthly invoice.

Plaid

Public OpenAPI file, llms.txt with about 250 entries and a Markdown twin of every docs page. No prices before a Production application, and Transactions, Liabilities and Investments bill per Item each month until removed.

Enable Banking

1. Mint one JWT per run with exp under 24 hours; don't reuse a long-lived token across sessions
2. Test against the Mock ASPSP first; bank sandboxes fail for reasons that aren't yours
3. Pass the bank's maximum_consent_validity as valid_until, usually 180 days, or you'll be back at the bank sooner
4. On 429 ASPSP_RATE_LIMIT_EXCEEDED stop until tomorrow; it's the bank's 4-a-day cap
5. Follow continuation_key until it's absent to get every transaction

Plaid

1. Point calls at https://sandbox.plaid.com until you hold a Production secret; request shapes are the same
2. Create a sandbox Item with /sandbox/public_token/create and ins_109508, then /item/public_token/exchange, no Link UI needed
3. Use /transactions/sync with its cursor and back off on 429 RATE_LIMIT_EXCEEDED yourself, since no Retry-After comes back
4. Call /item/remove when the user is done, or subscription products keep billing
5. Send an idempotency_key on /transfer/authorization/create so a retried request can't authorise twice
