■ Challenge detected

Multiplies the copper quantity by literature emission factors for the chosen secondary route and for primary cathode production, and reports the difference as low, typical and high. The factors are published life cycle averages and are stated in the response; they are not a certified product carbon footprint and are not a valid basis for a carbon credit, a customer declaration or an audited claim.

POST/copper-co2$0.002Multiplies the copper quantity by literature emission factors for the chosen secondary route and for primary cathode production, and reports the difference as low, typical and high. The factors are published life cycle averages and are stated in the response; they are not a certified product carbon footprint and are not a valid basis for a carbon credit, a customer declaration or an audited claim.
POST/cable-mass$0.002Conductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually.
POST/awg-metric$0.001Uses the geometric AWG definition, so results are exact for solid round conductors. Mass per metre and resistance follow from the material density and resistivity at 20 degrees Celsius; stranded conductors carry roughly two to five percent more mass and resistance per metre than the same nominal size and are not modelled separately. Supply either awg or cross_section_mm2, not both. Sizes 4/0 through 40 AWG are covered.
POST/cable-type-vision$0.005Downloads one HTTPS image through the hub SSRF guard, then asks the configured OpenAI vision model for strict structured JSON. It reports observed features and readable markings, at most five ranked type candidates, and conductor material, core count or cross-section only where the image supports them; unknown values remain null or unknown. The result is identification assistance, not an electrical safety clearance, approval, voltage-state determination or substitute for inspection and testing.
