Yes. GET https://api.lastscanned.com/v1/track/:number?carrier=postnl returns PostNL tracking as JSON, in the same shape as every other carrier lastscanned covers. Sign up for a free key with 5 lookups a day, or Pro for $4.99 a month with 1,000 numbers.

PostNL barcode: 3S + 4 letters + 7–9 digits; UPU S10: AA123456785NL. For example 3SABCD1234567. lastscanned recognizes these formats on its own, so ?carrier=postnl is optional for them.

Tracking pages are for people. This is for your code.
