## Which one, for what

### Flinks (D)

Good for: A lender or fintech with steady volume that needs Canadian bank data, income and lending attributes, PDF statements or Canadian bank payments.

Ahead on:
- Reliability, 53 against 27
- Schema & documentation, 83 against 48
- Payments & pricing, 25 against 10

Watch for: Live access needs a contract with a monthly minimum and a one-year term. The pricing page says there is no pay-as-you-go plan or self-serve trial

### Powens (E)

Good for: A European product, strongest in France, that needs account and transaction data plus wealth, loan and document data under Powens' own licence.

Ahead on:
- Security & auth, 60 against 50

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No OpenAPI or other machine-readable contract was found. The reference is hand-written tables

## 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
