Chemical ingredients disclosed for one well by API number.

Tool description as the model sees it

Chemical ingredient list disclosed for one well, by API number (the American Petroleum Institute well identifier, e.g. “42-317-37262-00-00” or “4231737262” — dashes optional). Returns, per disclosed job on that well: trade name, supplier, purpose (e.g. “Surfactant”, “Biocide”, “Proppant”), CAS number, ingredient name, percent of the hydraulic fracturing job by mass, and mass in pounds; trade-secret ingredients carry no CAS number and the claimant company instead. Ingredient-level detail is only loaded for jobs on or after this pack’s coverage cutoff (see data_as_of/ingredients_since in the response) — a well found in frac_wells but outside that window returns found:false with reason “outside_ingredients_coverage”, distinct from reason “unknown_api_number” when the well itself does not exist in FracFocus at all.

`api_number`	string	yes	API well number, with or without dashes, e.g. “42-317-37262-00-00” or “4231737262”.
`limit`	number	no	Max ingredient rows, 1-500. Default 100.
