## 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 minia2a-avogadro-constant-lookup-2e89b5d8
```

Example prompt: Can you look up the exact value of Avogadro's constant, including its units, using the minia2a avogadro endpoint?

## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call lookup of the Avogadro constant within an automated agent workflow, especially when using the x402 micropayment protocol and need a lightweight single-constant data source rather than a full scientific constants database.

## Known failure modes

- Missing or malformed 'input' object in request body returns a validation error
- Invalid query parameters cause a 400 bad request
- Payment not provided or insufficient results in a 402 Payment Required response
- Endpoint temporarily unavailable returns a 5xx error
