## Operations

- POST /api/v1/electrical-engineering/load-schedule-calculate — $0.04 USDC — Calculate electrical load schedules: Calculate kW, kVA, and current for caller-supplied loads using supplied voltage and power factor. Missing values are not invented. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-load-schedule-calculate
- POST /api/v1/electrical-engineering/three-phase-load-balance-check — $0.03 USDC — Check three-phase load balance: Compare phase-leg currents from supplied loads and report imbalance percentage. Optional caller rule thresholds are compared when provided. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-three-phase-load-balance-check
- POST /api/v1/electrical-engineering/voltage-drop-calculate — $0.04 USDC — Calculate voltage drop: Calculate voltage drop from supplied cable resistance/reactance, length, and load current. Cable tables are not invented. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-voltage-drop-calculate
- POST /api/v1/electrical-engineering/cable-sizing-calculate — $0.04 USDC — Check cable sizing: Compare calculated design current to caller-supplied cable ampacity. Ampacity tables are not invented. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-cable-sizing-calculate
- POST /api/v1/electrical-engineering/breaker-rating-check — $0.03 USDC — Check breaker ratings: Compare calculated design current to caller-supplied breaker ratings and continuous factors. Code rules are not invented. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-breaker-rating-check
- POST /api/v1/electrical-engineering/transformer-capacity-calculate — $0.04 USDC — Calculate transformer capacity: Compare transformer rated kVA to supplied or schedule load kVA and report loading percentage. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-transformer-capacity-calculate
- POST /api/v1/electrical-engineering/power-factor-correction-calculate — $0.03 USDC — Calculate power factor correction: Calculate required kVAR (and optional capacitance) to move from a supplied power factor to a supplied target. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-power-factor-correction-calculate
- POST /api/v1/electrical-engineering/generator-sizing-calculate — $0.04 USDC — Calculate generator sizing: Size required generator kVA from supplied load and caller diversity, reserve, and derate factors. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-generator-sizing-calculate
- POST /api/v1/electrical-engineering/ev-charger-load-capacity-check — $0.04 USDC — Check EV charger load capacity: Check EV charger design current against caller-supplied panel capacity and existing load. Continuous factors are used only when supplied. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-ev-charger-load-capacity-check
- POST /api/v1/electrical-engineering/design-document-audit — $0.08 USDC — Audit electrical design documents: Audit completeness of supplied electrical design inputs and aggregate load, balance, drop, cable, breaker, transformer, PF, generator, and EV checks. Does not invent code compliance. Docs: https://www.brainiac.software/api/electrical-engineering/docs#electrical-engineering-design-document-audit
