    "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."
