Ntriq X402 Document Intel

Extract text, classify document type, and pull tables from any document image. Pay $0.05 USDC per call via x402 (no API key needed).

Security Scan

The skill claims local, no-cloud document analysis but its runtime instructions require uploading images and performing an on‑chain micropayment — a clear mismatch and potential privacy/cost risk.

Purpose & Capability

The description repeatedly claims "local AI vision" and "No cloud upload," but SKILL.md instructs the agent to POST images (or base64) to https://x402.ntriq.co.kr/document-intel — i.e., remote processing. That contradiction is disproportionate to the stated purpose and misleading.

Instruction Scope

Instructions tell the agent to transmit document images (via URL or base64) to an external endpoint and to include an EIP-3009-signed payment header. This directs the agent to send potentially sensitive document content off‑agent and to perform a payment-signing flow not described in the metadata. The SKILL.md does not explain how to obtain or safely sign the required payment payloads.

Install Mechanism

No install spec and no code files — instruction-only. This minimizes local persistence and install-time risk.

Credentials

The skill declares no required environment variables or credentials, yet the runtime requires signing an on‑chain payment (EIP-3009), which implicitly needs wallet access/private-key signing or an external wallet UI. The lack of declared credential requirements is inconsistent and hides a material requirement (ability to sign/pay).

Persistence & Privilege

always:false and no install steps; the skill does not request elevated or persistent platform privileges.

What to consider before installing

This skill is suspicious because it markets "local" processing while instructing you to upload documents to a remote server and pay $0.05 USDC per call. Before installing or using it: (1) Do not send sensitive documents until you confirm the provider's privacy policy and data retention practices. (2) Understand the payment flow — EIP-3009 requires signing a payload with your wallet; never paste your private key into an agent. Use a trusted wallet UI to sign and verify the recipient address (0x124AaFfF8Ef45F2cA953807aF09Aacec2D9F8307). (3) Verify the service domain and TLS certificate and consider testing with non-sensitive images. (4) If you require strictly local processing, this skill does not provide it despite its marketing. (5) If you need more assurance, ask the publisher for a clear explanation of how payments are signed, whether image data is stored, and a privacy/security whitepaper; lack of those answers is a red flag.

Document Intelligence (x402)

Analyze document images — invoices, contracts, forms, reports — with local AI vision. Extracts text, classifies document type, pulls tables, or summarizes. No cloud upload, no API key. Pay $0.05 USDC per call via x402 micropayment (Base mainnet).

How to Call

POST https://x402.ntriq.co.kr/document-intel
Content-Type: application/json
X-PAYMENT: <x402-payment-header>

{
  "image_url": "https://example.com/document.png",
  "analysis_type": "extract"
}

The server responds with 402 Payment Required first. Sign the EIP-3009 payment payload and retry with X-PAYMENT header.
