# SignalDesk AI – Long Ton to Pound Converter

> SignalDesk AI – Long Ton to Pound Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a mass value from imperial long tons to pounds using IEEE-754 double precision arithmetic.

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 signaldesk-ai-long-ton-to-pound-converter-9c20e1fa
```

Example prompt: Convert 2.75 long tons to pounds for me.

## When to prefer this

Use this endpoint when you need a fast, deterministic, single-step conversion from imperial long tons to pounds with IEEE-754 double precision. Prefer it when the input unit is specifically long tons (not short tons or metric tonnes) and the output must be in pounds. It is a minimal, stateless computation endpoint suitable for any agent needing reliable mass unit conversion without building conversion logic internally.

## Known failure modes

- Missing required 'value' query parameter returns an error response
- Negative input values are rejected (minimum: 0)
- Extremely large values beyond 1e+100 are rejected by schema validation
- Non-numeric input for value causes a validation error
- Service unavailable if Cloudflare Worker is down or rate-limited

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the original value and unit ('long-ton'), the converted value in pounds, the dimension ('mass'), and the precision standard used (IEEE-754 double). Example: {from: 'long-ton', to: 'pound', value: 123.45, converted: 276528, dimension: 'mass', precision: 'IEEE-754 double'}.
