TenderBase grabs fresh notices every day from TED, converts them into OCDS releases and stores it in its database. Note that only those notices are being processed which are using the newer TED-XML (2.0.9) schema.
The API provides an easy way to access release and procurement process information in JSON format, using OCDS. You can find JSON API links on list and detail pages.
