Agent Ready REST API

The Agent Ready REST API scores any public URL against ~70 checks across the Vercel Agent Readability Spec, the llmstxt.org standard, and the agent-protocol manifests (MCP server cards, A2A agent cards, agents.json, agent-permissions.json, UCP, x402, NLWeb). Use this skill when the user wants to run a scan programmatically without setting up an MCP server — start a scan, poll for results, summarise the highest-impact findings.

When to use

Use when the user wants an HTTP-based agent-readability scan and does not have the Agent Ready MCP server installed — if they do, prefer the agent-ready-mcp skill (same surface, fewer moving parts). Trigger phrases are in the description above.

Step 1: Locate the API key

Agent Ready API access requires a Pro account. Work through these scenarios in order:

A) AGENT_READY_API_KEY is already set

printenv AGENT_READY_API_KEY

If it returns a value, you're ready. Skip to Step 2.
