## 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 can-bus-decoder-mcp-e572ccb7 -d '<json body>'
```

Example prompt: Can you decode this raw CAN bus frame for me: '18FEF100#FFFF00FA00FFFFFF'? I need to know what signals and values are inside it.

## When to prefer this

Choose this endpoint when you need to programmatically decode raw CAN bus frames or hex payloads into structured, human-readable signals — particularly for automotive diagnostics, vehicle telematics, or industrial embedded network analysis where CAN protocol parsing is required.

## Known failure modes

- Malformed or invalid CAN frame data returns a parsing error
- Unsupported CAN frame format or protocol variant may yield incomplete decoding
- Missing or empty data field returns validation error
- Unknown DBC/signal database entries may result in raw hex output without signal names

## 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 decoded CAN bus frame content, including parsed signal names, values, data types, and engineering units extracted from the raw input data string.
