## Verdicts

**Powens.** Powens documents a REST API with Markdown docs, cursor pagination, date filters and a hard-delete call for connections, under a French payment institution licence. No OpenAPI file, public price, status page, idempotency key or server SDK was found, and live access needs a signed purchase order.

**Salt Edge Account Information.** 5,000-plus banks in more than 50 countries, by Salt Edge's own count. Rate limit exceeded returns HTTP 406 RateLimitExceeded, not 429.

## Before you call either

### Powens

1. Ask the owner for the domain name, client ID and client secret from the console. Every call goes to `https://{domain}.biapi.pro/2.0`
2. Send `limit` on every transactions list. It is required, at most 1,000, and the next page comes from `_links.next.href` used as given
3. Enable an account with `POST` and `{"disabled": false}` only after the account holder consents. Accounts arrive disabled with no transactions
4. Store the permanent user token as a secret. It does not expire, and the default webhook sends it in the `Authorization` header
5. Stay under 30 calls a minute in the sandbox and use webhooks in place of polling, as the fair usage policy asks

### Salt Edge Account Information

1. Treat HTTP 406 with error_class RateLimitExceeded as a rate limit and back off; it isn't a content-negotiation error
2. Start with fakebank_simple_xf in country XF; it needs no bank sandbox
3. Sign requests from the start even in Test, so the move to Live doesn't change your client
4. Follow next_page from the meta block rather than building from_id URLs yourself
5. Revoke with PUT /api/v6/consents/{consent_id}/revoke when the user is done
