Shipping Data API
Every Royal Mail price as clean JSON. UK Click & Drop services and International Tracked zones — every format, every weight band, VAT broken out — behind one API key. Stop copying prices out of PDFs; pull them into your checkout, invoicing or dashboards instead.
One Bearer-key API serving the full Royal Mail tariff as structured JSON. Pull the whole price matrix once a day and compute prices locally, or request a live quote per shipment — the same API that powers our WooCommerce Royal Mail rates plugin at real checkouts.
version hash changes — your integration knows exactly when to re-sync. No re-keying prices every April.Price a 750g small parcel on Tracked 24 — one request, one JSON answer:

Two datasets, both included in the one price:
The API serves the same dataset that powers our public Royal Mail prices page and our live WooCommerce rates plugin. It tracks Royal Mail's published tariff — Royal Mail typically reprices each April, and any change flows straight through to the API. Every matrix response carries a version hash and a freshness timestamp, so your integration can tell at a glance whether anything changed.
Fair use, no hard metering. The matrix endpoints are designed to be fetched once a day and cached — that's one request per day for most integrations, with prices computed locally on your side. The quote endpoints are there for live lookups and self-tests. If your use case needs sustained high-volume quoting, tell us and we'll make sure you're on the right setup.
