pay-for-service
Make a paid API request to an x402 endpoint with automatic USDC payment. Use when you or the user want to call a paid API, make an x402 request, use a paid service, or pay for an API call. Use after finding a service with search-for-service.
Security
3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.80). The SKILL.md explicitly instructs calling arbitrary HTTP(S) endpoints via the command "npx awal@2.10.0 x402 pay <url>" (examples like https://example.com/api/...), which fetches and ingests responses from open/public third‑party APIs that the agent would use as part of its workflow and could thus contain instructions that influence subsequent actions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.80). The skill requires running "npx awal@2.10.0", which at runtime fetches and executes the "awal" package from the npm registry (e.g. https://registry.npmjs.org or via the npm registry URLs), so external remote code is fetched-and-run as a required dependency.
W009: Direct money access capability detected (payment gateways, crypto, banking)
What this means
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Why it was flagged
Direct money access detected (high risk: 1.00). The skill is explicitly designed to execute on-chain crypto payments: it provides a concrete command ("npx awal@2.10.0 x402 pay <url>") that performs automatic USDC payments on Base, references wallet authentication and USDC balance checks, uses USDC atomic units and a --max-amount payment parameter, and ties to an authenticate-wallet/fund workflow. This is not a generic HTTP or automation tool — its primary and explicit purpose is sending token payments (crypto/wallet operations), so it grants direct financial execution capability.
