## Verdicts

**MX Platform API.** Three public OpenAPI files, llms.txt, Markdown docs and a written version policy with 18 months of support and `Deprecation` and `Sunset` response headers. No price, client agreement or SLA is published, production keys need MX's approval, every calling IP address must be allowlisted, and the status page records three platform-wide error incidents since 10 July 2026.

**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

### MX Platform API

1. Send `Accept: application/json`, `Accept-Version: v20260929` and Basic auth of `client_id:api_key` on every call. A missing version returns 406
2. Ask the owner to allowlist the calling machine's static IP in the Client Dashboard first. Other addresses get 403, and some failed authentication returns 404
3. Test against `https://int-api.mx.com` with institution `mxbank`, username `mxuser` and any password. It has no aggregation throttle
4. Set your own `id` when creating users and members. A repeat returns 409, which makes a retried create safe
5. Expect 202 without an error when a standard aggregation is throttled (three hours by default). Balance checks stop at 5 per member every 2 hours with 429
6. Pass `includes[]=merchant` or `includes[]=category` as an array on transaction lists. A comma-separated string returns 400

### TrueLayer

1. Use auth.truelayer-sandbox.com and api.truelayer-sandbox.com with a separate sandbox client; live credentials don't work there
2. Send the user's IP when they're present, or a bank allows 4 calls a day per account
3. Check the retry column of the Data API error table before retrying; codes marked No need the user or a config fix
4. Set data_access_type to one_time for a single read and skip the 90-day reauthorisation
5. Append .md to any docs URL to get the page as Markdown
