How this service works
Agent-readiness scan of any public website: scores 0-100 on MCP server, /.well-known/agent.json, llms.txt, OpenAPI validity, JSON-LD catalog and x402/MPP payability. Same published methodology as the asterpay.io checker. Paid via x402.
Output
Returns a JSON object with a numeric score (0-100), a readiness bucket ('invisible', 'partial', or 'agent-ready'), a signals object with per-dimension earned vs weighted scores, and a top_gaps array listing the most impactful missing agent features.
Example use cases
Vetting a partner API for agent compatibility
“Scan api.openai.com and tell me its agent-readiness score — specifically whether it has an MCP server, a valid OpenAPI spec, and x402 payment support, and what the top gaps are.”
Auditing your own site before launch
“Can you run the agent-readiness scan on my site mystartup.io and tell me what score it gets and what I need to fix to reach 'agent-ready' status?”
Competitive benchmarking of AI-facing platforms
“I want to compare how agent-ready three platforms are — can you scan anthropic.com, cohere.com, and mistral.ai and tell me each one's score and which bucket they fall into?”
Technical details
Endpoint
GEThttps://x402.asterpay.io/v2/x402/agent-readinessWhen to prefer
Use this endpoint when you need a structured, multi-dimensional audit of whether a public website meets AI agent interoperability standards — especially if you want a single score covering MCP, llms.txt, OpenAPI, JSON-LD, and x402 payability in one call. Prefer this over manual inspection or single-signal checks when you need a normalized, comparable score across multiple domains.
Side effects
- Private or loopback hostnames rejected with 4xx error
- Unreachable or non-public URLs return an error
- Malformed URL input causes validation failure
- Upstream DNS/network timeouts may return incomplete signals
- Payment not provided or incorrect amount returns 402
