How this service works

How ready a website is for AI agents: llms.txt, AI-crawler rules in robots.txt, sitemap, x402 payment discovery, OpenAPI, MCP manifest, security.txt, with a 0-100 score and concrete recommendations.

Output

Returns a JSON object with an overall readiness score (0–100), per-file existence checks (llms.txt, llms-full.txt, openapi.json, sitemap.xml, mcp.json, ai-plugin.json, x402, security.txt) each with URL, HTTP status code, and boolean exists flag, plus a robots.txt breakdown listing which AI bots are permitted or blocked, and an array of actionable recommendations.

Example use cases

Audit competitor site for AI readiness

“Can you scan https://openai.com and tell me whether it has llms.txt, an OpenAPI spec, MCP configuration, and whether it allows AI crawlers like ClaudeBot and GPTBot?”

Pre-integration agent compatibility check

“Before I integrate with https://api.stripe.com, can you check if they have agent-readiness signals like x402 support, an AI plugin manifest, and an openapi.json published?”

Self-check before launching a new API

“I just launched https://myapi.io — can you run an agent-readiness check on it and tell me what files are missing and what my score is?”

Technical details

Endpoint

POSThttps://api.vextorium.com/v1/agent-readiness?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to programmatically audit whether a website exposes the standard AI-agent discovery files (llms.txt, openapi.json, mcp.json, ai-plugin.json, x402) and allows AI bots via robots.txt. Prefer this over manual inspection when building agent pipelines that need to auto-discover compatible endpoints, or when vetting third-party APIs for agent integration.

Side effects

Target URL is unreachable or returns timeout — scan may return partial results
Invalid or malformed URL input causes validation error
Target site blocks the scanner's requests — results may show false negatives
Rate limiting on the target site may affect status codes returned
