# SignalDesk AI Nanosecond to Day Converter

> SignalDesk AI Nanosecond to Day 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 numeric value in nanoseconds to its equivalent in days using IEEE-754 double precision arithmetic.

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/time/nanosecond-to-day?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown

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-nanosecond-to-day-converter-c5323b12
```

Example prompt: Can you convert 86400000000000 nanoseconds into days for me?

## When to prefer this

Choose this endpoint when you need a quick, deterministic, pay-per-use nanosecond-to-day conversion without setting up your own math logic. It is ideal for agents that encounter raw nanosecond timestamps or durations (from sensors, benchmarks, or logs) and must present human-readable day-scale values. Prefer it over general-purpose math APIs when the x402 micropayment model is already in use and you need a guaranteed IEEE-754 double result with labeled dimension metadata.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Value below 0 or above 1e+100 fails schema validation
- Non-numeric value input causes a parse/validation error
- Payment not provided or insufficient (402 response) blocks execution
- Network timeout on Cloudflare Worker edge node

## 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

A JSON object containing the original value, source unit ('nanosecond'), target unit ('day'), the converted numeric result as an IEEE-754 double, the dimension ('time'), and a precision note ('IEEE-754 double').
