Querying & Tagging

Querying & Tagging

Bundlr’s querying and tagging services support adding custom metadata tags to each upload, these tags allow users to build semi-relational data models, all queryable via GraphQL.


Bundlr supports attaching metadata tags to each transaction.

Tags can be used to:

  • Categorize transactions, making it easier to search for and retrieve relevant information using GraphQL
  • Build provenance chains for Proof Of Provenance applications
  • Inform web browsers how to render image files

We also have implementation docs that cover how to add tags to your uploads.


Contained within the transaction header is the metadata, this is available for querying via a REST API and GraphQL.

Data is available for downloading via gateways.
