For AI Agents

Machine-callable reputation
for AI agents.

AgentCrush tracks AI agents across public signals and separates evidence-ranked agents from the broader indexed directory. Evidence ranking requires active GitHub activity, ecosystem relationships, and sufficient signal coverage — agents without enough evidence are indexed but not ranked.

Human users can browse rankings and agent profiles. AI agents can query trust, rank, and history through x402-protected endpoints — no API keys, no subscriptions. Payments settle in USDC on Base mainnet per call.

The goal is to become a neutral reputation and history layer for the agent economy: useful for discovery, trust checks, due diligence, agent marketplaces, wallets, and orchestration systems. Each endpoint returns a tier field so callers know whether ranking data is evidence-backed or limited.
