/install ntriq-x402-sentiment
Description
Analyze sentiment, emotions (joy/anger/sadness/fear), and intent from any text. Pay $0.01 USDC via x402.
Usage Guidance
This skill legitimately calls an external sentiment API and charges $0.01 per call, but it omits how to produce or supply the required X-PAYMENT header. Before installing or using it: (1) Do not paste private keys or seed phrases into the agent — if a payment header must be supplied, prefer generating it client-side or using a single-purpose/burner wallet. (2) Ask the publisher how X-PAYMENT is produced and whether a short-lived payment token can be used instead of a private key. (3) Verify the API hostname (https://x402.ntriq.co.kr) and review their payment docs; consider testing with minimal funds on a disposable wallet. (4) If you need stronger assurance, request implementation code showing how the payment header is created so you can confirm it doesn't require exposing long-term secrets.
Capability Analysis
Type: OpenClaw Skill
Name: ntriq-x402-sentiment
Version: 1.0.0
The skill bundle provides documentation for a sentiment analysis API service hosted at x402.ntriq.co.kr. It describes a legitimate commercial model requiring a $0.01 USDC payment per call via the x402 protocol on the Base mainnet. No executable code, data exfiltration logic, or malicious instructions were found in SKILL.md or _meta.json.
Capability Tags
Capability Assessment
Purpose & Capability
The name/description (sentiment + pay-per-call) match the SKILL.md: it calls a sentiment endpoint and charges $0.01 USDC. However, the skill does not declare any required credentials or environment variables even though the API requires an X-PAYMENT header for payment, which is a meaningful omission.
Instruction Scope
Instructions are narrowly scoped to calling POST https://x402.ntriq.co.kr/sentiment with a JSON body and X-PAYMENT header — no file reads, system paths, or unrelated network endpoints. But the doc gives no guidance on how to create/obtain the X-PAYMENT header or what the agent should do if it doesn't have one.
Install Mechanism
Instruction-only skill with no install spec and no code files, so nothing is written to disk or installed. This is low-risk from an install perspective.
Credentials
Payment requires an X-PAYMENT header (implying wallet signing or a payment token). The skill lists no required env vars or primary credential, so there's no declared, safe place for the agent to retrieve payment credentials. That mismatch raises a risk that the agent will prompt the user for sensitive wallet keys/tokens or that a user might paste private material into the agent.
Persistence & Privilege
always:false and no install actions. The skill does not request permanent presence or elevated agent privileges.
