Verdicts

Flinks

Ten public OpenAPI files, an llms.txt index with Markdown twins and published sandbox keys let an agent start without a signup. Live access needs a one-year contract from $500 a month, keys never expire, no rate-limit numbers are published, and the status page logged 77 incidents in 90 days.

Powens

Powens documents a REST API with Markdown docs, cursor pagination, date filters and a hard-delete call for connections, under a French payment institution licence. No OpenAPI file, public price, status page, idempotency key or server SDK was found, and live access needs a signed purchase order.

Before you call either

Flinks

  1. Call /GenerateAuthorizeToken with the secret key in flinks-auth-key, then pass the returned token to the Connect iframe or to /Authorize. The token is single-use and expires after 15 minutes.
  2. Send the account holder through Flinks Connect in a browser. The API alone cannot complete a first bank login, and sandbox iframes need demo=true.
  3. Store the loginId. Call /Authorize with it and MostRecentCached: true for a new requestId each session, because /GetAccountsDetail consumes the requestId.
  4. On a 202 from /GetAccountsDetail, poll /GetAccountsDetailAsync every 10 seconds for at most 30 minutes, or ask support to enable webhooks.
  5. Route each end user to the instance for their country. A loginId from the Canadian instance is not valid on the US one.

Powens

  1. Ask the owner for the domain name, client ID and client secret from the console. Every call goes to https://{domain}.biapi.pro/2.0
  2. Send limit on every transactions list. It is required, at most 1,000, and the next page comes from _links.next.href used as given
  3. Enable an account with POST and {"disabled": false} only after the account holder consents. Accounts arrive disabled with no transactions
  4. Store the permanent user token as a secret. It does not expire, and the default webhook sends it in the Authorization header
  5. Stay under 30 calls a minute in the sandbox and use webhooks in place of polling, as the fair usage policy asks
