Cost-optimised endpoint selection: name a capability (web search, token safety, enrichment) and get the x402 endpoints that provide it ranked cheapest-first in USDC per call, filtered by real adoption so untested $0.0001 listings do not masquerade as bargains. Refreshed daily from the Bazaar discovery index. `offset`/`limit` page through the full ranked list (up to 100 rows per call); `cheapest` always names the globally cheapest listing, whichever page you asked for.
