Calculate power factor correction API

Calculate required kVAR (and optional capacitance) to move from a supplied power factor to a supplied target.

The Calculate power factor correction operation is part of the Electrical Engineering & Installation Intelligence API on BRAINIAC.software. Calculate required kVAR (and optional capacitance) to move from a supplied power factor to a supplied target. It is exposed as POST /api/v1/electrical-engineering/power-factor-correction-calculate and priced at $0.03 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Caller-supplied loads, cables, breakers, transformers, power-factor cases, generators, chargers, and optional rule thresholds Limitations: No paid engineering data provider is used and no API key is required. Deterministic formulas use caller-supplied voltages, currents, impedances, ratings, and factors. Missing values are not invented. Electrical code or safety compliance is not claimed. Caller-supplied rule thresholds are compared when present; standards tables are not invented. Cable ampacity tables, breaker continuous factors, and derating rules are applied only when the caller supplies those values. Design audits report completeness and calculation conflicts only from supplied records. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Calculate electrical load schedules, Check three-phase load balance, Calculate voltage drop, Check cable sizing.

An unpaid probe returns HTTP 402 with x402 payment requirements. After paying the exact USDC amount on Base, retry the identical request with a payment-signature header.

FAQ

  • Do I need an API key? No. Pay the listed USDC amount with x402.
  • What network? Base (eip155:8453), USDC.
  • Is this an official determination? No. Results are for human review against the cited sources.
