H-Index

Built for the agentic economy

H-Index is the first product in the H-Series, a family of on-chain primitives built on Hedera by XR Utilities.

The agentic economy needs a discovery layer that's verifiable, spam-free, and not dependent on any single operator's longevity. Free registries get flooded. Centralized ones disappear. H-Index uses paid registration plus on-chain anchoring to solve both.

H-Series (Hedera)
  • H-Index
    Capability registry. Live.
  • H-Seal

  • H-Mailbox

XR-Series (XRPL)

    XRPL monitoring.
  • XR-Telemetry
