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 allinonecents-exchange-rate-api-0e8fb66b -d '<json body>'
```

Example prompt: What is the current exchange rate from USD to EUR? Use the AllInOneCents exchange rate endpoint with the query 'USD to EUR exchange rate'.

## When to prefer this

When you need a cheap ($0.01), low-friction exchange rate or currency conversion lookup that accepts natural-language queries and supports both crypto and fiat pairs. Best for agent workflows that need casual, flexible querying without strict schema requirements.

## Known failure modes

- Query string is ambiguous or unsupported currency pair — may return empty or null data
- Payment not processed — 402 response blocking access
- Generic or vague query string results in incomplete rate data
- Service unavailable or upstream data source unreachable — success: false

## How this service works

## Output

Returns a JSON object with a success boolean and a data object containing the exchange rate or conversion information for the queried currency pair or asset.
