# Decision Data Studio Unit Converter

> Decision Data Studio Unit Converter is a paid API for AI agents from api.ikoles.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Converts a numeric value between units within a specified physical domain (e.g. pressure, temperature, length, electrical)

## Facts

- Endpoint: POST https://api.ikoles.dev/v1/unit-convert
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability decision-data-studio-unit-converter-355732b6 -d '<json body>'
```

Example prompt: Convert 2.5 bar to psi in the pressure domain — I need the exact result and the formula used.

## When to prefer this

Choose this endpoint when you need precise, formula-transparent unit conversion across engineering and scientific domains including pressure, temperature, length, force/torque, electrical, flow, thermal, and mass density — especially when the conversion formula itself needs to be returned for auditability or documentation. Prefer it over general-purpose calculators when working in technical or industrial contexts requiring domain-scoped accuracy.

## Known failure modes

- Unsupported unit pair within the specified domain returns an error
- Invalid or misspelled unit strings cause a 4xx error
- Domain mismatch (e.g. passing a length unit under pressure domain) returns an error
- Missing required fields (value, from, to, domain) cause a validation error
- Non-numeric value input causes a schema validation failure

## How this service works

Local-first data and agent workflow tools from Decision Data Studio, plus verified EU tender shortlists and machine-callable utilities.

## Output

A JSON object containing the converted numeric result, the input value, source and target units, the domain, and the mathematical formula used for the conversion.
