## 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 stablecoin-reserves-lookup-18fbc063
```

Example prompt: What are the current reserves backing USDC — can you pull the reserve data for that stablecoin?

## When to prefer this

Use this endpoint when you need on-demand, per-symbol stablecoin reserve data and are willing to pay a small per-call fee via x402 micropayment. Prefer this over manual research when building automated DeFi risk assessment, compliance checks, or portfolio monitoring workflows that require programmatic reserve lookups.

## Known failure modes

- Unknown or unsupported stablecoin symbol returns an error or empty result
- Malformed symbol parameter causes a 400-level error
- Upstream reserve data source unavailable causes a 500-level error
- Payment not fulfilled results in a 402 payment required response

## Output

Returns reserve information for the requested stablecoin symbol, including data about the backing assets or collateral supporting the stablecoin's peg.
