Comparing address API pricing means looking past headline numbers to the per-lookup rate at your actual volume, plus whether the data is PAF-licensed and what's included.
| Model | How it works | Best for |
|---|---|---|
| Monthly plan | Fixed fee with included lookups each cycle | Predictable, steady volume |
| Pay-as-you-go | Buy credit packs, use as needed | Spiky or seasonal volume |
| Enterprise / custom | Negotiated rate at high volume | Very large or bespoke needs |
What to check before you buy
Confirm the data is Royal Mail PAF-backed, the per-lookup rate at your tier, whether limits reset each cycle, and if there are setup fees. See cheapest UK address API and our pricing page.
