# Assay Systems > Government contract intelligence. [Register hub](https://assay-systems.com/register/). Each supplier page states what the register records for one company since January 2024: contracts or award notices, value, buyers, first contract with the government. Each line page lists every supplier in one line of business. Each buyer page lists the suppliers that sold to one department or agency. Pages are static HTML and are rebuilt from the registers. ## Registers - [All countries](https://assay-systems.com/register/): the hub of every register on the site, with search across suppliers and lines - [Canada](https://assay-systems.com/register/ca/): Government of Canada contract register; suppliers, lines, and departments - [United States](https://assay-systems.com/register/us/): USAspending register; suppliers, lines, and agencies - [Australia](https://assay-systems.com/register/au/): AusTender register; suppliers, lines, and agencies - [New Zealand](https://assay-systems.com/register/nz/): GETS register; suppliers, lines, and agencies - [United Kingdom](https://assay-systems.com/register/uk/): Contracts Finder register; suppliers, lines, and buyers - [Ireland](https://assay-systems.com/register/ie/): TED register; suppliers, lines, and buyers - [Norway](https://assay-systems.com/register/no/): Doffin register; suppliers, lines, and buyers - [Sweden](https://assay-systems.com/register/se/): TED register; suppliers, lines, and buyers ## Open tenders - [Canada: open tenders by line](https://assay-systems.com/register/ca/open/): notices open on CanadaBuys, matched to the lines of the register; rebuilt every day - [RSS feed of open tenders](https://assay-systems.com/register/ca/open/feed.xml); each line has its own feed at /register/ca/open//feed.xml ## Canada: contracts and grants - [Government contracts](https://assay-systems.com/register/ca/contract/): every contract the Government of Canada has disclosed since 1 January 2022, one page each, with its amendments and procurement method - [Grants and contributions](https://assay-systems.com/register/ca/grants/): every agreement by department, riding and recipient, one record per agreement ## Excluded firms - Supplier pages carry an Exclusions section where the firm is on an official exclusion list (SAM.gov, World Bank, Government of Canada), with the awards dated inside the exclusion period ## API - [API key](https://assay-systems.com/api-key/): Enterprise Data; /api/v1 answers only with a key ## Method - [Method](https://assay-systems.com/method/): sources, one contract per award, excluded firms, grants, updates - [Amendments](https://assay-systems.com/register/amendments/): amendments recorded in the registers after award ## Optional - [Sitemap](https://assay-systems.com/sitemap.xml): every page of the registers - [Terms](https://assay-systems.com/terms/)
