## 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:
- 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

### TrueLayer (B)

Good for: UK data and payments from one licensed vendor, with EEA coverage through the Irish entity on Data v1.

Ahead on:
- Reliability, 71 against 53
- Schema & documentation, 89 against 83
- Agent ergonomics, 73 against 54
- Security & auth, 66 against 50
- Maintenance & community, 38 against 31

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

Watch for: No public pricing anywhere on the site or in the docs

## 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.

**TrueLayer.** FCA and Central Bank of Ireland authorised, holding the AISP and PISP licences itself. No public pricing anywhere on the site or in the docs.

## 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.

### TrueLayer

1. Use auth.truelayer-sandbox.com and api.truelayer-sandbox.com with a separate sandbox client; live credentials don't work there
2. Send the user's IP when they're present, or a bank allows 4 calls a day per account
3. Check the retry column of the Data API error table before retrying; codes marked No need the user or a config fix
4. Set data_access_type to one_time for a single read and skip the 90-day reauthorisation
5. Append .md to any docs URL to get the page as Markdown
