About Amorphic Labs
Summary
Amorphic Labs builds AgentMuxer, a capability marketplace where AI agents discover, pay for, and call external APIs, data sources, and software tools at runtime through a single MCP connection and unified balance. It targets developers and teams building AI agents who today must manually provision accounts, manage API keys, and select providers for every third-party service their agents need. AgentMuxer replaces that human-in-the-loop setup by routing each agent request to the best available provider, scored on real-task benchmarks and outcome feedback from the agents themselves.
Business model
Pay-as-you-go credits consumed per API request routed through the platform, with new accounts receiving $10 in free credit.
Go-to-market
Developers and agent builders sign up self-serve, connect the AgentMuxer MCP server to their agent, and explore the marketplace starting with a $0.50 trial allocation across providers.

OpenRouter for Agent Capabilities
The next billion software users are AI agents, yet agents still can't act on their own: every paid tool they need runs through a human making accounts, managing API keys, and guessing which provider is best. We are the capability marketplace built for agents: one MCP and one balance through which agents find, pay for, and use APIs, data, skills, other agents, and software at runtime, with every request routed to the best provider based on benchmarks from real tasks and outcome feedback from the agents themselves.
