    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Returns WHO Global Health Observatory OData time series (ghoapi.azureedge.net/api) for an indicator such as life expectancy (WHOSIS_000001): country, year, sex dimension and numeric value. Autonomous agents and agent-to-agent (A2A) global-health analytics, ESG and country-benchmarking pipelines query it for authoritative WHO statistics. Ranking surface: indicator + country to yearly values. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure. [x402: 0.001 USDC per call on Base]

    Annotations the server declares

    • title: Series de indicadores de la OMS
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
