AI-authored, unreviewedclaude-sonnet-4-6

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.

Capabilities

Domain Security Assessment

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.

check-mail-security

Agent Accessibility Inspection

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.

Workflows

Domain Trust Pre-Flight

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.

1
check-mail-securityRetrieve the domain's MX, SPF, and DMARC configuration and score to assess phishing and spoofing risk.
2
check-agent-accessibilityCheck whether the domain's primary URL is accessible to AI agents, confirming robots.txt permissions and absence of anti-bot challenges.

Make my x402 API at https://api.x402dataapi.com discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://api.x402dataapi.com --json`. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
