## 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 4-20ma-analog-signal-converter-3eed070f -d '<json body>'
```

Example prompt: Convert this 4-20mA analog sensor reading of 12mA to its corresponding engineering unit value given a range of 0 to 100 PSI.

## When to prefer this

Use this endpoint when you need to programmatically convert raw 4-20mA analog current loop readings from industrial sensors, PLCs, or SCADA systems into meaningful engineering unit values, especially in IoT automation pipelines where real-time signal interpretation is required.

## Known failure modes

- Invalid or out-of-range milliamp value (below 4mA or above 20mA) causing conversion error
- Missing or malformed data string input returning a 400 error
- Unspecified engineering unit range preventing accurate scaling
- Service unavailability returning 402 or 5xx errors
- Ambiguous data format in the input string leading to incorrect conversion

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns the converted engineering unit value corresponding to the input 4-20mA current signal, scaled according to the defined measurement range and process variable parameters.
