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 basic-utils-agent-ec3107b4 -d '<json body>'
```

Example prompt: Can you calculate the standard deviation of the numbers 12, 15, 20, 22, and 30, and also convert 100 miles to kilometers?

## When to prefer this

Choose this endpoint when you need quick, on-demand computation for arithmetic, basic statistics, unit conversions, or date/time calculations without setting up a local library or code execution environment. It is especially useful for AI agents that need to offload numeric reasoning to a reliable utility service in a single natural language call. Prefer alternatives if you need complex symbolic math, real-time data lookups, or batch processing of large datasets.

## Known failure modes

- Ambiguous or malformed question may produce an unclear or incorrect answer
- Questions outside the supported domains (calculator, statistics, datetime, unit conversion) may not be answered accurately
- Payment failure or insufficient USDC balance may block access entirely
- Network timeout on Railway-hosted deployment may return no response
- Unsupported unit types or edge-case mathematical inputs may produce errors
