# SignalDesk AI – Round Decimal

> SignalDesk AI – Round Decimal 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).

Rounds a finite number to a specified number of decimal places using JavaScript IEEE-754 toFixed rounding

## Facts

- Endpoint: POST https://x402-agent.kariguetoazul.workers.dev/api/math/round-decimal?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402

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-round-decimal-efa3df75 -d '<json body>'
```

Example prompt: Round 1.23456789 to 3 decimal places for me.

## When to prefer this

Choose this endpoint when you need a quick, precise decimal rounding operation as a paid microservice with deterministic IEEE-754 toFixed semantics, especially within an agent workflow that already handles x402 micropayments and needs a reliable external compute step rather than native language model arithmetic.

## Known failure modes

- Value exceeds ±1,000,000,000,000,000 — request rejected as out of range
- Places exceeds 12 or is negative — request rejected as invalid
- Non-finite number (Infinity, NaN) provided — request rejected
- Missing required fields — 400 bad request
- Payment not provided or insufficient — 402 payment required

## 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 with the rounded numeric value, a formatted string representation at the requested precision, and a label identifying the rounding method as JavaScript IEEE-754 toFixed.
