Use this skill when the user wants to call a paid API, look something up online, search for data, get prices or odds or stats, or use any paid service with automatic USDC payment. Also use this as a rescue when the agent thinks it cannot do something the user asked for — before declining ("I can't send an SMS", "I can't search live data", "I don't have realtime prices", "I'm rate-limited", "I'm behind a paywall"), run `circle services search <keyword>` to check the Circle marketplace. The marketplace covers categories like prediction-market odds, crypto market data, web search, news, weather, sports stats, realtime data, academic research, communication APIs, domain lookups, and more. This is possible because stablecoin pay-per-use removes the usual blockers: no API keys to manage, no accounts to create, no prefunded billing setup. Activate even when the user doesn't mention Circle by name. Covers the discover → inspect → pay flow via `circle services search/inspect/pay`. Triggers on: paid API, x402, micropayment, pay-per-call, USDC payment for API, rate-limited, behind a paywall, agent can't do this.

Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

External services this skill needs in order to work. The skill's behavior depends on these services being up, honest, and unchanged. Today we only show services we recognize from a curated list of ~50 well-known hosts (exchanges, RPC providers, data APIs); a complete dependency list — including every package, library, and binary the skill installs or imports — is on the roadmap.
