I built Spread, an API for New Zealand grocery data.
Groceries are really expensive in New Zealand and there is barely any competition in the supermarkets monopolies that control the whole grocery market
I was originally collecting grocery pricing data for ButterUp.app, a supermarket comparison app I’ve been building for NZ.
At some point I realised the data layer was probably useful on its own, so I pulled it out into a separate API. So, that anyone who is building a business to open a grocery supermarket in NZ, they can get latest prices of their competitors and based on that they can price their own products.
Spread currently covers products and pricing from Pak’nSave, New World and Woolworths (the giant supermarkets over here in New Zealand).
It gives you:
* product search * current price observations * competitor price comparisons * structured API responses * API keys and usage limits * MCP support for AI agents
The main use cases I had in mind were price comparison apps, grocery analytics, AI shopping tools, businesses adjusting their prices based on grocery market conditions, and anything else that needs NZ supermarket data without having to build the collection layer from scratch.
It’s still early.
There’s a 7-day free trial if anyone wants to play around with it.
Would be keen to get feedback, especially from people who have built data APIs, scraping pipelines, MCP servers, or developer tools.
Happy to answer technical questions about how I’m collecting, normalising and serving the data.
