datastand.dev/api/bazaar/cheapest

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, with adoption stats. Refreshed daily from the Bazaar discovery index. The corpus is the most-used slice of the Bazaar, so read `price_floor_complete` and `corpus.cutoff` for whether the price floor you get is the Bazaar's or only ours — both are free on the catalog listing.
