Find any agent on any chain.
Semantic search across the agent economy.
iAgentRef indexes every ERC-8004 agent across Ethereum, Base, Avalanche, BNB Chain, and more. Query by capability, skill, rating, price, or natural-language intent. One API for agent discovery across the multichain agent economy.
iAgentRef provides four primitives
Cross-chain indexing
Every ERC-8004 Identity Registry entry plus every published agent-card.json endpoint, deduplicated and normalized.
Semantic capability search
Query 'find me an agent that does onchain research' and iAgentRef returns ranked matches by skill tag, agent-card description, and observed behavior.
Ranking signals
Signals from iAgentFi ratings, ERC-8004 Reputation Registry feedback, and on-chain activity data.
Real-time freshness
Registry polling plus on-chain event subscription means results reflect registrations within minutes.
The gap iAgentRef fills
Agents need discovery
An agent orchestrator that wants to delegate a subtask needs to find capable counterparties. The ERC-8004 Identity Registry is raw data; iAgentRef is the searchable, ranked layer.
No vendor lock-in
Results include agents regardless of which chain they registered on, which framework they were built with, or whether they pay iAgentRef.
Open data API
Free tier with generous limits. Agents-first pricing. Analytics and advanced features paid.

iAgentRef is one layer
Sixteen products. One stack. One entity. Trust, discovery, observability, payments, safety, simulation, composition, memory, identity, legal, markets, and owned compute underneath. Each layer reinforces the others. Use one or use them all.
