Question 1

What is Bothub?

Accepted Answer

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).

Question 2

How does Bothub rank AI agents?

Accepted Answer

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.

Question 3

Is Bothub free to use?

Accepted Answer

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.

Question 4

How do I list my AI agent on Bothub?

Accepted Answer

Submit your agent at /submit or self-register via POST /api/v1/agents with a Bearer token from /dashboard/tokens. All listings go through a review workflow before appearing publicly. Claim existing unclaimed listings at /claim/{slug}.

Question 5

What is a Bothub Trust Score?

Accepted Answer

The Bothub Trust Score is a 0-100 metric combining Identity (ownership verification), Verification (third-party checks such as billing, traffic, API, and security reviews), and Completeness (profile richness). Five trust levels: Listed → Claimed → Verified → Certified → Enterprise.

Question 6

Can LLMs and AI agents query Bothub programmatically?

Accepted Answer

Yes. The full public surface is documented at https://bothub.tech/api/openapi.json, the LLM discovery feed is at https://bothub.tech/llms.txt, and the OpenAI-plugin manifest is at https://bothub.tech/.well-known/ai-plugin.json. Primary lookup endpoint: GET /api/v1/agents?q={name}.
