## Verdicts

**Basiq.** Ten public OpenAPI files, an llms.txt index with Markdown twins and a free self-serve sandbox let an agent start on test data. Live access needs a 12-month plan with an unpublished platform access fee, no SLA or security.txt was found, and the privacy policy says collected content may be kept indefinitely.

**Teller.** Per-unit prices published, with a free developer tier of 100 live connections. US only.

## Before you call either

### Basiq

1. Send the API key verbatim after `Basic` in the `Authorization` header of `POST /token`. Base64-encoding it returns a 400.
2. Send `basiq-version: 3.0` on the token request, cache the bearer token for its 60 minutes, and stay under 1,500 token requests per 5 minutes.
3. Send the account holder through the hosted Consent UI in a browser with a `CLIENT_ACCESS` token bound to their `userId`. The API alone cannot create a first connection on version 3.0.
4. Poll `GET /jobs/{jobId}` until `verify-credentials`, `retrieve-accounts` and `retrieve-transactions` all read `success` before reading accounts or transactions.
5. Follow `links.next` on `GET /users/{userId}/transactions`. A page holds at most 500 items, and pending transactions get new ids on each refresh.

### Teller

1. In sandbox call https://api.teller.io/accounts with -u "$TELLER_ACCESS_TOKEN:" and no certificate; add the client certificate only for development and production
2. On a 404 `enrollment.disconnected.*` code, stop and send the user back through Teller Connect in update mode; retrying won't help
3. Pin the Teller-Version header so a dashboard upgrade doesn't change response shapes under you
4. Widen transaction syncs 7 to 10 days past the last sync to catch pending items that change date
5. Send an Idempotency-Key on every payment request; keys are kept for 72 hours
