What Treasury Prime (BYOK) is for

Treasury Prime (BYOK) lets an AI assistant read your own Treasury Prime data through the Treasury Prime API with a key you supply (API key ID (the username of the key pair)). Read-only: 10 tools (list_accounts, get_account, list_daily_balances, list_account_transactions, list_transactions, list_ach_transfers, list_wire_transfers, list_book_transfers, list_incoming_ach, list_incoming_wires). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.treasuryprime.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Treasury Prime. Treasury Prime and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "What bank accounts do I have in Treasury Prime?"
  • "What is the available balance of Treasury Prime account acct_qda4pJZfpzn4fc?"
  • "Show the daily balances of Treasury Prime account acct_qda4pJZfpzn4fc this month"
  • "What transactions posted on Treasury Prime account acct_qda4pJZfpzn4fc last week?"
  • "What are the latest transactions across my Treasury Prime accounts?"
  • "Which Treasury Prime ACH transfers are still pending?"

BYOK key

You bring your own Treasury Prime API key ID (the username of the key pair) (https://docs.treasuryprime.com/docs/getting-started). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.treasuryprime.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Treasury Prime API (api.treasuryprime.com) with a BYOK key; documentation: https://docs.treasuryprime.com/reference/get_account. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Treasury Prime.
