New Zealand has Wilderlab, for example, https://www.wilderlab.co.nz/ https://www.wilderlab.co.nz/, the UK has Nature Metrics https://www.naturemetrics.com/ https://www.naturemetrics.com/ They send you usually a syringe with some filter paper in it, you push water through the filter paper, send the paper back, and they sequence the DNA stuck in the paper and send you a report (and add the sightings to their database).
