APIs for Agents
Agents discover, evaluate, and connect to APIs directly.
No dashboards. No signups. Just APIs.
Apps are dead. API-first. Agent-native.

MCP-native. Works with Claude, GPT, and any agent that speaks the protocol.

How do I add APIClaw to my agent?
Install the MCP server with 'npx @nordsym/apiclaw init' and add it to your Claude config. Your agent can then discover APIs by capability, not by name.
