## 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 rwa-nav-reserve-verification-f1fc4783 -d '<json body>'
```

Example prompt: Can you verify whether the declared NAV and reserves for this tokenized real estate fund match what independent sources show — here's their reported NAV of $42M and reserve breakdown?

## When to prefer this

Choose this endpoint when an agent needs to independently validate the accuracy of declared NAV, reserve, or collateral figures for real-world assets or tokenized funds — particularly before investment decisions, compliance checks, or when auditing issuer attestations. Prefer it over generic data lookup when you specifically need a comparison between declared and independently sourced figures with discrepancy detection.

## Known failure modes

- Input body missing required NAV or reserve fields — returns validation error
- Independent source data unavailable or stale — verification cannot be completed
- Asset identifier unrecognized — no matching independent data found
- Declared figures format incompatible with expected schema — parsing failure
- Network timeout when retrieving independent source data

## How this service works

Compare declared NAV, reserves and collateral with independently retrieved sources

## Output

Returns a structured comparison of the declared NAV, reserves, and collateral against independently retrieved data, highlighting any discrepancies, mismatches, or inconsistencies between the declared figures and the verified values from external sources.
