IPNI

Welcome to the InterPlanetary Network Indexer (IPNI) organization on GitHub.

IPNI is a content routing system optimized to take billions of CIDs from large data providers, and provide fast lookup of provider information from these CIDs over a simple HTTP REST API.

See IPNI specification for more information.

See:

  • storetheindex - a reference implementation of IPNI indexer nodes.
  • index-provider - a Golang library to advertise content onto IPNI.
  • go-libipni - a Golang library of common utilities to build out your own IPNI integration.
  • depute - a gRPC wrapper to advertise content onto IPNI from just about any other programming language.
  • relayX - separates ingest logic from the underlying indexer, which allows further scaling.
