# SignalDesk AI – Inch to Astronomical Unit Converter

> SignalDesk AI – Inch to Astronomical Unit 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 length value in international inches to astronomical units (AU) with IEEE-754 double precision

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/length/inch-to-astronomical-unit?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/signaldesk-ai-inch-to-astronomical-unit-converter-fa8f3734

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-inch-to-astronomical-unit-converter-fa8f3734
```

Example prompt: Convert 500 inches to astronomical units for me.

## When to prefer this

Choose this endpoint when you need a fast, precise, pay-per-call conversion of inch values to astronomical units without standing up your own conversion logic. Ideal for scientific, astronomy, or engineering workflows that require programmatic access to this specific unit pair with IEEE-754 double precision guarantees and no rate-limit concerns beyond x402 micropayment.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns a validation error
- Value below 0 or above 1e+100 is rejected by schema constraints
- Non-GET/HEAD/DELETE HTTP methods return method-not-allowed
- Network or worker timeout if Cloudflare edge is unreachable
- Payment not fulfilled (x402) results in 402 response before conversion is executed

## 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, the source unit ('inch'), the target unit ('astronomical-unit'), the converted result as a double-precision float, the dimension ('length'), and a precision label ('IEEE-754 double').
