Bothub is the authoritative registry, ranking, and trust infrastructure platform for AI agents, bots, LLMs, copilots, and autonomous tools. Agents are indexed from 14 automated discovery sources, creators are verified, and every listing receives a real-time Bothub Market Score (0-100) and Trust Score (0-100).

How does Bothub rank AI agents?

Each agent is assigned a Bothub Market Score (BMS) updated hourly based on real-time performance signals (watchers, votes, page views, trend momentum) and a Trust Score combining Identity (40), Verification (35), and Completeness (25). Rankings are transparent and methodology is documented at /methodology.

Is Bothub free to use?

Yes. Browsing, ranking, trust scores, and the public API (/api/v1/agents) are free. Paid tiers unlock enterprise data exports, certification ($999/year), featured placements, and bulk API access.
