x402 merchant
DiscoveryRouterConciergeSearchMarketplace

x402 concierge: describe what you need in plain language plus a maxPrice, and we find the best working paid API among ~18,000 x402 endpoints on Base (CDP Bazaar, PayAI Bazaar, x402scan, 402index), health-check it live, call it for you paying the upstream provider ourselves, and return its result. One payment, one call, no need to discover, vet or pay individual services. Price = upstream price + max($0.002, 20%) (our own render402 tools at list price), never above your maxPrice; the unpaid request returns a free quote naming the chosen service. Settled only if the upstream call succeeds.
