x402_search_services — Your first call when you do not know which x402 service exists for a job: it narrows a directory of 500+ listed services to candidates.
x402_get_service — Call this once you hold a slug and are deciding whether to commit to that service: the full record behind a directory row.
x402_find_best_service — Call this when you have a need in words and want one service to call rather than a list to read: it is the free ranking step between searching and paying.
x402_check_health — Call this before you send a payment, or right after a call unexpectedly failed: is this service up right now.
x402_facilitator_volumes — Call this when the question is about the rail rather than the service: which x402 facilitator actually settles money, and how much.
x402_assess_services — Call this when the free signals have run out: you hold 2 to 8 finalists from x402_search_services or x402_find_best_service, their stored fields do not separate them for YOUR stated need, and choosing wrong costs more than a quarter.
