    "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/3). 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 a minute.",
    "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."
