apiosk_discover
ActiveTool of Apiosk
declared in 1.7.0
Find the best paid x402 API for a data capability across discovery sources (Apiosk catalog + federated external listings). Decompose the user's request into capability segments first, then call this once per capability. Returns a normalized, ranked list; each result's `executable_via` says whether to call apiosk_execute (Apiosk-settled) or apiosk_inspect_x402 + apiosk_fetch_paid (external). Use this instead of apiosk_search when the goal is 'get real paid data for X', not just browsing.
