/install ntriq-x402-screenshot-data
功能描述
Convert screenshots into structured data — extract text, UI layout, tables, or charts from any screen image. Pay $0.02 USDC via x402.
安全使用建议
This skill will upload screenshots to a third-party endpoint (x402.ntriq.co.kr) and charges $0.02 USDC per call. Before installing: (1) Confirm how the X-PAYMENT header is generated and who controls the payment flow — do not supply private wallet keys to the skill; (2) Avoid sending sensitive screenshots (passwords, personal data, corporate secrets) because they will leave your environment; review the service's privacy, retention, and security policies and TLS certificate; (3) Test with non-sensitive images and verify responses/costs; (4) If you require on-device/offline extraction for privacy, consider local OCR alternatives instead of this remote service.
功能分析
Type: OpenClaw Skill
Name: ntriq-x402-screenshot-data
Version: 1.0.0
The skill bundle describes a legitimate-looking API service for extracting structured data from screenshots using the x402 micropayment protocol. The documentation in SKILL.md clearly outlines the API endpoint (https://x402.ntriq.co.kr/screenshot-data), parameters, and the cost ($0.02 USDC), with no evidence of malicious code, data exfiltration, or prompt injection attacks.

Purpose & Capability
Name/description (screenshot → structured data) match the instructions: a single POST to https://x402.ntriq.co.kr/screenshot-data with image_url or image_base64 and an X-PAYMENT header. No unrelated binaries, env vars, or installs are requested.
Instruction Scope
Instructions stay within the stated scope (call the x402 API). However, they require sending screenshots (potentially sensitive) to a remote service and do not explain how to obtain or generate the required X-PAYMENT header. The SKILL.md does not instruct reading local config or other system files, which is good.
Install Mechanism
Instruction-only skill with no install spec or code files; no files are written to disk by the skill itself. Low installation risk.
Credentials
The skill declares no environment variables, credentials, or config paths. The only external requirement is an X-PAYMENT header for payment; the repo doesn't request wallet keys or other broad credentials.
Persistence & Privilege
always is false and the skill does not request persistent privileges or modify other skills. Autonomous invocation is allowed by default but is not combined with other privilege escalations.
