## 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 15

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

### Plaid (B)

Good for: US and Canadian account, transaction, identity and income data, with Transfer for payments.

Ahead on:
- Reliability, 68 against 53
- Schema & documentation, 93 against 83
- Agent ergonomics, 82 against 54
- Security & auth, 67 against 50
- Maintenance & community, 83 against 31
- Transparency & trust, 79 against 60

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Open source

Watch for: No prices before a Production application, and Transactions, Liabilities and Investments bill per Item each month until removed

## 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.

**Plaid.** Public OpenAPI file, llms.txt with about 250 entries and a Markdown twin of every docs page. No prices before a Production application, and Transactions, Liabilities and Investments bill per Item each month until removed.

## 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.

### Plaid

1. Point calls at https://sandbox.plaid.com until you hold a Production secret; request shapes are the same
2. Create a sandbox Item with /sandbox/public_token/create and ins_109508, then /item/public_token/exchange, no Link UI needed
3. Use /transactions/sync with its cursor and back off on 429 RATE_LIMIT_EXCEEDED yourself, since no Retry-After comes back
4. Call /item/remove when the user is done, or subscription products keep billing
5. Send an idempotency_key on `/transfer/authorization/create` so a retried request can't authorise twice
