Ntriq X402 Blueprint

AI architectural blueprint analysis — extract rooms, dimensions, materials from floor plans. $0.05 USDC via x402.

Security Scan

The skill's stated purpose (local vision-based blueprint analysis) mostly matches its API, but it contradicts the 'local' claim, requires an undocumented payment header, and instructs sending potentially sensitive floorplan images to an external service — these inconsistencies and data-exfiltration/payment uncertainties merit caution.

Purpose & Capability

The name/description and SKILL.md describe extracting rooms, dimensions, materials from blueprints — the provided POST API is consistent with that capability. However the doc claims 'Uses local vision AI' while the runtime instructions send images to a remote endpoint (x402.ntriq.co.kr), which is a clear contradiction. The skill also references an X-PAYMENT header for $0.05 USDC per call but declares no credential or payment mechanism in the metadata.

Instruction Scope

Runtime instructions direct the agent to POST blueprint images (URL or base64) to an external service and include an X-PAYMENT header. That means any image you submit (often sensitive) will be transmitted off-device. The SKILL.md does not explain how to obtain or validate the X-PAYMENT header, nor does it provide privacy/retention guarantees. No other file-system or environment access is requested, but the external-network data exfiltration of potentially sensitive blueprints is the main risk.

Install Mechanism

Instruction-only skill with no install spec or code files — nothing is written to disk and no third-party packages are installed. This is lower technical risk, but does not mitigate the network/data risks noted above.

Credentials

The skill declares no required environment variables or credentials, which limits direct access to secrets. However, it uses an X-PAYMENT header (undocumented in metadata) for paid calls; the absence of a declared payment credential is an inconsistency. Also, because the skill posts images externally, you may be required to provide payment/authentication interactively or via headers — be cautious about where/how you supply any wallet keys or tokens.

Persistence & Privilege

always is false and there is no install behavior or persistent modification of agent settings. The skill does not request elevated persistence or modify other skills.

What to consider before installing

This skill will send the blueprint images you provide to https://x402.ntriq.co.kr and charges $0.05 USDC per call via an X-PAYMENT header. Before installing or using it: (1) Confirm you trust the x402 service and review its privacy/retention policy — floorplans can be sensitive. (2) Clarify how the X-PAYMENT header is issued and whether you must expose wallet credentials; never paste private keys into a skill. (3) Note the SKILL.md says 'local vision AI' but the API is remote — ask the author which is correct. (4) If you need confidentiality, prefer a verified local processing tool or a vetted vendor; test with non-sensitive samples first. (5) If you proceed, limit what images you upload and monitor any charges on your wallet/address.

Blueprint Intelligence (x402)
