/install ntriq-x402-invoice-extract-batch
Description
Batch extract structured data from up to 500 invoices/receipts. Flat $9.00 USDC via x402.
Usage Guidance
This skill asks you to send invoice images to an external API and to include an X-PAYMENT header for a $9 USDC charge, but it does not say how to obtain or store that payment token and even claims '100% local inference' while pointing to a remote endpoint — those are red flags. Before installing or using it: 1) Ask the publisher to explain exactly how X-PAYMENT is generated, whether it requires wallet private keys, and whether you must provide any secrets. 2) Verify the vendor (x402.ntriq.co.kr) and read their privacy/retention policy for uploaded invoices. 3) Do not provide private keys or wallet seed phrases; prefer a pre-issued payment token or an audited on-chain payment flow. 4) If you will send sensitive invoices, confirm whether images are uploaded to the vendor or processed locally and whether data is stored. If the publisher cannot clearly document the payment flow and data handling, treat the skill as risky and avoid using it.
Capability Analysis
Type: OpenClaw Skill
Name: ntriq-x402-invoice-extract-batch
Version: 1.0.0
The skill bundle consists of documentation for an external API service (https://x402.ntriq.co.kr/invoice-extract-batch) designed to perform batch OCR and data extraction from invoice images. There is no executable code provided, and the instructions in SKILL.md are limited to standard API request/response formats and payment processing via the x402 protocol, with no evidence of malicious intent, data exfiltration, or prompt injection.

Capability Assessment
Purpose & Capability
The skill advertises local inference on a Mac Mini but the SKILL.md instructs the agent to POST image URLs to https://x402.ntriq.co.kr/invoice-extract-batch, a remote endpoint — these claims conflict. The payment flow (flat $9 USDC via x402) is central to the service, yet no environment variables or credentials are declared for providing the required X-PAYMENT header. Requiring a blockchain payment or payment header would be proportionate for this purpose, but the skill fails to declare how that credential is obtained or stored.
Instruction Scope
The instructions direct the agent to transmit user-provided invoice/receipt image URLs (potentially sensitive financial data) to an external endpoint and to include an X-PAYMENT header. The SKILL.md does not specify where the X-PAYMENT value should come from, how to obtain/authorize it, or any privacy/retention guarantees. There is no guidance on how to handle uploading images (the example uses URLs), error handling, or user consent for sending sensitive documents off-platform.
Install Mechanism
This is an instruction-only skill with no install spec and no code files, so it does not add binaries or write files to disk during install — low install-time risk.
Credentials
No environment variables or primary credential are declared, yet the API requires an X-PAYMENT header for payment. If the payment header maps to a wallet key or token, that is a secret the skill should have declared and justified. The absence of declared credentials is a gap: the agent (or user) must supply a payment token somehow, but the SKILL.md doesn't explain the mechanism, expected format, or whether private keys/wallet access is required.
Persistence & Privilege
The skill does not request always:true and uses default invocation settings. There is no install-time behavior that would modify other skills or system-wide settings. Autonomous invocation is permitted but is the platform default and not an additional risk here by itself.
