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 creator-desk-number-absolute-value-api-946f4e2f -d '<json body>'
```

Example prompt: What is the absolute value of -47.83? Just give me the non-negative result.

## When to prefer this

Choose this endpoint when you need a reliable, machine-callable absolute value computation within an x402 micropayment-enabled autonomous agent workflow, especially when you want a standardized JSON response with operation metadata rather than doing inline math. Useful when computation is being delegated to an external utility service for auditability or workflow consistency.

## Known failure modes

- Missing or non-numeric 'value' input returns an error
- Invalid JSON body causes a 400-level response
- Payment failure or insufficient USDC balance causes a 402 response
- Extremely large or malformed numbers may cause computation errors
- Service downtime on Render.com free tier may cause 502/503 responses

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

A JSON object containing the computed absolute value under a 'result' field and an 'operation' field confirming 'number_abs', indicating the mathematical operation performed.
