Ntriq X402 Screenshot Data

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward paid screenshot-to-data API helper, but users should treat uploaded screenshots as shared with an external service.

Install only if you are comfortable sending selected screenshots to ntriq's external API and paying per call via x402. Do not submit screenshots containing passwords, tokens, personal data, financial records, customer information, or confidential dashboards unless you have confirmed the service's privacy and retention practices.

Finding

The skill explicitly sends screenshots to a third-party remote endpoint for processing, but the description provides no warning that screenshots may contain sensitive personal, financial, or internal business information. Users or downstream agents may upload confidential screen captures without informed consent, creating a real risk of unintended data disclosure to the service operator and any systems involved in storage, logging, or model processing.
