## 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 44
- Schema & documentation, 83 against 54
- Payments & pricing, 25 against 10
- Maintenance & community, 31 against 3
- Transparency & trust, 60 against 52

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

### GoCardless Bank Account Data (E)

Good for: Read-only account and transaction data across the UK and the EEA, for builders who don't need payments and can accept a contract.

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

Watch for: No public price and no confirmed free plan

## 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.

**GoCardless Bank Account Data.** UK plus every PSD2 country, up to 24 months of history, one API shape for all of them. No public price and no confirmed free plan.

## 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.

### GoCardless Bank Account Data

1. Cache the access token for its 24 hours and use /api/v2/token/refresh/ rather than minting a new pair each run
2. Create the end user agreement before the requisition when you need other than 90 days of history or access
3. Read the per-account rate limit headers; on 429 wait for the account reset time, since some banks allow 4 calls a day
4. Poll /api/v2/accounts/{id}/ until status is READY before asking for transactions
5. Call the REST endpoints directly; the Nordigen SDKs still install but get no fixes
