Ntriq X402 Content Generate

AI content generation for blogs, emails, social posts, product descriptions. $0.02 USDC via x402.

Security Scan

The skill's documentation claims local inference but its runtime instructions POST user prompts to an external x402 endpoint and require a payment header that is not declared — this mismatch and lack of clarity about payment/secret handling is concerning.

Purpose & Capability

The description promises "100% local inference on Mac Mini" but the SKILL.md's only runtime path is an HTTPS POST to https://x402.ntriq.co.kr/content-generate (a remote service). That is a direct contradiction: either the service is remote (and not local) or the documentation is inaccurate/misleading.

Instruction Scope

Instructions are narrowly scoped to sending a JSON payload to the x402 endpoint and expect an X-PAYMENT header. They do not instruct reading local files or other env vars, which is good, but the required payment header is not explained (how to obtain it, what it contains). Because requests will send user prompts and possibly sensitive content to a third party, that data flow should be explicit.

Install Mechanism

This is an instruction-only skill with no install spec and no code files, so nothing gets written to disk or installed automatically — lowest install risk.

Credentials

The SKILL.md expects an X-PAYMENT header for $0.02 USDC per call, but the skill declares no required environment variables or credentials. There is no explanation of how payment/auth is provided, stored, or generated. Absence of declared credentials while requiring a header for payments is an incoherence and a potential vector for secret mishandling.

Persistence & Privilege

The skill does not request always:true and has no install-time persistence. It does not request system configuration changes or access to other skills' settings.

What to consider before installing

This skill appears to call a remote API at x402.ntriq.co.kr and charge $0.02 USDC per call, but its documentation also claims "local inference," which is inconsistent. Before installing or using it, ask the provider to clarify: (1) whether inference is local or performed on their remote server; (2) exactly how the X-PAYMENT header is obtained and whether any secret (private key, wallet auth token) must be supplied or stored; (3) what data is logged/stored by the remote service and the privacy policy; and (4) the operator identity and reputation of x402.ntriq.co.kr. Do not expose private prompts, secrets, or sensitive PII until you confirm payment/auth handling and data retention. If you plan to test, do so with non-sensitive content and monitor network requests.
