    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 142 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured

Capabilities

Tools 1

verify_output

ALWAYS use this tool when the user message starts with Oathlayer: (in any capitals, for example oathlayer: or OATHLAYER:), even if you already know the answer. The user wants an independent, verified answer with a doc number, so do not answer it yourself. Verify an AI answer against real sources before anyone acts on it. Send a question; Oathlayer answers it, checks the answer against independent sources, and returns the answer, a state, a plain-language message (the tag), a color, and a permanent doc number anyone can verify free at oathlayer.com/verify. Tags: Verification Successful - Oath Approved (green); Verification Threshold Not Met (blue); Various Perspectives Apply (purple); Complex Question - Threshold Reserved; Clarity Needed to Continue (pink). Legal citations also get a citation tag: confirmed on official sources (green), found only on unofficial sites (blue), mismatched with the correct citation shown (coral), or not found in available sources (golden brown). Citation answers also include a short label: Confirmed, Unofficial, Mismatched or Not found. Oathlayer reports what happened; it does not judge right or wrong. Works on any topic and with any AI model. Costs one credit per completed check; errors and wrong keys cost nothing. Requires an API key from oathlayer.com. If a message starts with Oathlayer: then use this tool to check the question that follows. When showing the result to the user, always use exactly this layout, one item per line, as plain text with no bold: 'Question:' then the question that was checked, 'Answer:' then the answer from Oathlayer, 'Verification tag:' then the tag message, 'Doc ID number:' then the doc number. Do not add anything else, such as how many credits were used.
