# Operations reports and developer utilities

Choose a defined job, review its input example and price, then select a payment option. Private result access lasts30days; save your downloaded copy. Each is a one-time job, without a recurring commitment. Use authorized, non-sensitive input. The work is limited to the supplied records or mathematical profile, without external actions, professional certification or an outcome guarantee. Input and computation profiles describe the work included, not payment admission limits. A quote is unpaid; a signature alone does not establish settlement.

## Coaxial Parallel Disk View Factor

USD 1.00 per job.

Calculate mutually visible parallel coaxial disk view factors with cancellation-resistant evaluation and area reciprocity. Obstructions, offset axes and emissivity are excluded. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.

```json
{
  "records": [
    {
      "id": "R1",
      "emitterRadius": 1,
      "receiverRadius": 1,
      "separation": 1
    }
  ]
}
