Route
Selects a live paid API endpoint matching buyer spending and readiness rules, and returns routing evidence. Does not buy the seller's service. Seller payment is separate; the agent keeps the wallet. Use for fresh probing and constraint-based selection, or signed binding evidence before merchant sign. Use preview for free catalog discovery without probing. Use validate for an unpaid readiness check of one catalog-listed URL. Pass need (capability) and/or url (HTTPS). If both are set, url select
Preview
Discovers catalog-listed paid API endpoints by capability without paying or contacting sellers. Returns claimed listings and any earlier observations; not_probed=true means this is not a new live check. Freshness is for this search response, not each seller's last probe.

Use route when you need fresh probing, constraint-based selecti
