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.
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
Powens
- 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 - Send
limiton every transactions list. It is required, at most 1,000, and the next page comes from_links.next.hrefused as given - Enable an account with
POSTand{"disabled": false}only after the account holder consents. Accounts arrive disabled with no transactions - Store the permanent user token as a secret. It does not expire, and the default webhook sends it in the
Authorizationheader - Stay under 30 calls a minute in the sandbox and use webhooks in place of polling, as the fair usage policy asks
TrueLayer
- Use auth.truelayer-sandbox.com and api.truelayer-sandbox.com with a separate sandbox client; live credentials don't work there
- Send the user's IP when they're present, or a bank allows 4 calls a day per account
- Check the retry column of the Data API error table before retrying; codes marked No need the user or a config fix
- Set data_access_type to one_time for a single read and skip the 90-day reauthorisation
- Append .md to any docs URL to get the page as Markdown
