## 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.

**Yodlee Core API.** A public Swagger 2.0 file covers 98 operations with per-operation error codes, and tokens last 30 minutes and are bound to one end user. No price, service terms, status page, rate limit or SLA is published, there is no official server SDK, and the sandbox is limited to five preconfigured users with sample data.

## 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.

### Yodlee Core API

1. Get a token with `POST /auth/token`, sending `Api-Version: 1.1` and the end user's `loginName` as headers and `clientId` and `secret` in a form body. Reuse it for up to 30 minutes
2. Use the admin `loginName` only for administrative calls such as webhook subscriptions. A token made with a user's `loginName` reads only that user's data
3. In the sandbox, pick one of the five preconfigured users. Registering new users is not supported there
4. Page `GET /transactions` with `skip` and `top` (1 to 500). Without dates it returns the last 30 days, and at most two years with `fromDate` and `toDate`
5. A person must link accounts in FastLink 4 first. Then read `GET /providerAccounts` for link status before `GET /accounts`
6. Subscribe to `DATA_UPDATES` or `REFRESH` webhooks, or poll `GET /dataExtracts/events` in windows of at most 60 minutes, and do not poll accounts in a loop
