工具清单
工具（4）
⚪repair_json(input, schema, allow_llm_fallback)
Repair malformed JSON (trailing commas, single quotes, truncation, markdown fences, comments, python literals) and optionally validate/coerce it against a JSON Schema. Deterministic repair is free. If it fails and allow_llm_fallback is true, a paid LLM repair is attempted (requires x402 payment; charged only on success).

"allow_llm_fallback": {

"default": false,

}🟢validate_json(input, schema)
Validate a JSON string against a JSON Schema. Free. Returns validity and a list of violations.

"required": [

}🟢extract_json(input, schema, allow_llm_fallback)
Extract JSON embedded in arbitrary text — LLM prose, chat messages, logs, emails — then repair and validate it. Deterministic extraction is free. If no JSON can be located and allow_llm_fallback is true, a paid LLM extracts structured data from the text (requires x402 payment; charged only on success). Pass a JSON Schema to shape the output.

},
"required": [
"input"
]
}🟡infer_schema(input, as_samples)
Infer a JSON Schema (draft 2020-12) from an example JSON value. Free and deterministic. Set as_samples=true when the input is an array of example objects of the same shape to merge them into one schema. Turns sample agent/tool output into a reusable schema.
