{"ok":true,"host":"api.x402dataapi.com","status":"ready","manifest":{"positioning":"This host serves agents and developers that need lightweight pre-flight checks before interacting with external domains or URLs. It covers two distinct but complementary concerns: whether a domain is configured to resist email spoofing and phishing, and whether a target URL can be crawled by an AI agent without being blocked. It does not perform active email sending, real-time uptime monitoring, or any checks requiring authentication.","host_overview":"api.x402dataapi.com provides two DNS and HTTP inspection utilities: one checks a domain's email security configuration (MX, SPF, DMARC) and returns a numeric risk score, and the other checks whether a public URL is accessible to AI agents by inspecting HTTP status, robots.txt, sitemap, and anti-bot challenge signals. Both are single-shot, read-only checks against publicly observable infrastructure.","routing_guidance":"Use this host when an agent needs to perform pre-flight due diligence on an external domain or URL — specifically to assess email anti-spoofing configuration or to verify AI crawlability before attempting to fetch content. For email security checks (SPF, DMARC, MX scoring), this is the appropriate tool. For agent accessibility checks (robots.txt, llms.txt, challenge detection), use check-agent-accessibility. Do not use this host for real-time email deliverability testing, inbox placement verification, uptime monitoring, or any checks against private or authenticated endpoints. It is not a substitute for a full security audit or a web scraping framework — it only inspects publicly observable DNS and HTTP signals.","capability_clusters":[{"skill_names":["check-mail-security"],"cluster_name":"Domain Security Assessment","cluster_summary":"Inspects a domain's DNS-level email security records (MX, SPF, DMARC) and produces a numeric score with a list of identified configuration issues, enabling agents to evaluate phishing risk or anti-spoofing posture."},{"skill_names":["check-agent-accessibility"],"cluster_name":"Agent Accessibility Inspection","cluster_summary":"Determines whether a public URL is reachable and permissible for AI agent crawling by checking HTTP status, robots.txt rules, sitemap presence, llms.txt discovery, and anti-bot challenge detection."}],"cross_skill_workflows":[{"steps":[{"skill_name":"check-mail-security","description":"Retrieve the domain's MX, SPF, and DMARC configuration and score to assess phishing and spoofing risk."},{"skill_name":"check-agent-accessibility","description":"Check whether the domain's primary URL is accessible to AI agents, confirming robots.txt permissions and absence of anti-bot challenges."}],"when_to_use":"Use when an agent needs to evaluate the overall trustworthiness and reachability of an unknown domain before interacting with it — covering both its email security posture and whether its web presence is accessible to AI agents.","workflow_name":"Domain Trust Pre-Flight"}]},"model":"claude-sonnet-4-6","version_no":2,"generated_at":"2026-07-21T07:36:28.596Z","provenance":"ai_authored_unreviewed","ai_authored":true,"merchant_reviewed":false,"merchant_edited":false,"merchant_reviewed_at":null,"merchant_edited_at":null,"skill_md_url":"https://x402gle.com/servers/api.x402dataapi.com/SKILL.md","skills_url":"https://x402gle.com/servers/api.x402dataapi.com/skills.json"}
