## 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 sml-rwa-intelligence-suite-proof-of-reserves-6d57db3a
```

Example prompt: Can you pull the proof-of-reserves data for BUIDL and confirm it's fully backed?

## When to prefer this

Choose this endpoint when you need live, per-asset proof-of-reserves verification for real-world asset tokens — especially tokenized treasuries, money market funds, or bonds listed on DeFi protocols. It combines DefiLlama and CoinGecko data without synthetic or fabricated entries, making it trustworthy for collateral audits, risk checks, and investor due diligence. Prefer it over generic DeFi data APIs when you specifically need reserve attestation rather than price or liquidity data.

## Known failure modes

- Unknown or unsupported asset_id returns an error or empty result
- Stale data if upstream DefiLlama/CoinGecko feeds are delayed
- x402 payment failure if USDC balance or Base network transaction fails
- Network timeout if the Render.com host is under load
- Missing asset_id parameter results in a validation error
