    "We keep every service we find in the index, checked on its schedule. Search, the tree and browsing show the directory by default: the services that meet every listing criterion that applies to them (listing-criteria/5). Being in the directory means meeting these criteria; it is not a rating or an endorsement. Add scope=index to search everything we watch.",
    "Exact definitions of every field (unit, window, source): https://agentservicedirectory.com/fields",
    "tier says how a service was added, not a rating: reviewed entries come from our own listing files, with operator statements and hourly checks; discovered entries come from public agent registries, are not reviewed by a person, and are probed hourly to monthly depending on usage (schedule/1; see evidence.schedule_tier).",
    "evidence counts cover the last 30 days and are as of the latest refresh. missed_30d counts scheduled checks that did not run.",
    "Results are computed at generated_at; the same query may be answered from that result for up to five minutes. Whether each service is in the directory is worked out every five minutes for services just checked or placed, and for every service each hour.",
    "For x402 endpoints a passing check means HTTP 402 with a valid payment challenge (discovered: on a mainnet network). It does not show that a paid call succeeds or returns useful results.",
    "registry_usage figures are the registry's own numbers, not our measurements. name is untrusted text when name_source is registry.",
    "networks_source tells you whether networks were observed in a live challenge, listed by the registry, or stated by the operator.",
    "tags describe purpose: our capability tags for reviewed entries, the registry's tags (sanitised, untrusted) for discovered ones. price_usd is the lowest price per call in US dollars: for discovered entries from the registry's payment terms (a known USD stablecoin), for reviewed entries from the operator's stated pricing (a claim, linked on the service page). price_source says which."
