Gas Monitor Report Parser

This tool parses raw gas fee data for Ethereum, Base, and Polygon into a structured Gas Monitor report, including SafeLow, Standard, and Fast fee tiers. It accepts three inputs: chain (string enum: ethereum, base, polygon) to select the blockchain; fidelity (string enum: fast, standard, detailed) as an optional level of detail for the report; and raw_data, a required JSON string or unstructured text payload containing gas fee information to be interpreted. When raw_data is valid JSON, its contents are treated as the authoritative source of fee values. The tool transforms these inputs into a final structured Gas Monitor report whose output must strictly validate against the system-provided structured output schema, with no extra fields and correct types and enums.
