First the arguments are validated against the tool input schema and every violation is reported with its path and a sentence saying what to change. Second, values that satisfy the schema but look wrong are flagged: an unset required field filled with a placeholder like \"string\" or \"TODO\", a number at a suspicious order of magnitude, an address that fails its checksum shape, a destructive flag set to true, an empty string where content was expected."},{"url":"https://modell.halowerk.com/v1/drift-check","method":"POST","priceMicroUsd":3000,"networks":["eip155:8453"],"description":"Compares two submitted sample sets feature by feature and returns deterministic drift metrics. Continuous features are binned on the combined value range and receive PSI, Jensen-Shannon divergence and a Kolmogorov-Smirnov statistic; categorical features receive PSI and Jensen-Shannon divergence over exact category labels. The response names every feature, its sample counts, the metric values, the threshold used, and the reason a feature was flagged."},{"url":"https://modell.halowerk.com/v1/llm-catalog","method":"POST","priceMicroUsd":5000,"networks":["eip155:8453"],"description":"A comparison table of language models: input, output and cache prices per million tokens, context window, maximum output length, batch discount and a short note on what each is suited to. Filter by vendor, by a maximum price, by the context window you need, or by capability tag. Every row carries the date its prices were last checked, so a stale figure is visible rather than silently wrong."},{"url":"https://modell.halowerk.com/v1/llm-catalog-diff","method":"POST","priceMicroUsd":5000,"networks":["eip155:8453"],"description":"Use this when an agent has an older and a newer LLM catalog snapshot and needs a deterministic migration diff before changing routing or budgets. Rows are matched by vendor plus model, id or name. The result separates added, removed and changed models and reports field-level differences for input, output and cached-input price, context window and maximum output tokens."}]}
