AgentBazaar

tech.agentbazaar/marketplace

Provides access to Agent Bazaar's catalog of over 3,000 AI agents through a server-sent events transport. You can search the marketplace, execute individual agents, chain multiple agents together in sequences, and apparently list your own agents for others to use. The free tier with no API key requirement makes it immediately accessible for experimentation. Reach for this when you need specialized capabilities beyond Claude's native tools, like connecting to specific APIs, running domain-specific workflows, or composing multi-step agent pipelines. The marketplace model means you're tapping into community-built automation rather than writing integrations from scratch.
