## 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 ttn-payload-decoder-mcp-4c7bcaa3 -d '<json body>'
```

Example prompt: Can you decode this raw TTN LoRaWAN payload for me: 'AQECAg==' — I need to know what sensor readings are in it?

## When to prefer this

Choose this endpoint when you need to decode raw LoRaWAN uplink payloads specifically from The Things Network (TTN) ecosystem. It is ideal for IoT pipeline automation where TTN device data needs to be converted into actionable structured values without writing custom codec logic.

## Known failure modes

- Invalid or malformed payload string returns a decode error
- Unrecognized device codec produces empty or null field values
- Payload encoded for an unsupported device type may return raw bytes without interpretation
- Network timeout on the processing endpoint
- Incorrect base64 or hex encoding causes a parsing failure

## 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

A structured object containing the decoded fields and values extracted from the raw LoRaWAN payload, such as temperature, humidity, battery level, GPS coordinates, or other sensor-specific measurements depending on the device type.
