## 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 realedger-tokenized-treasury-money-market-fund-supply-b97c258e
```

Example prompt: Pull the latest on-chain circulating supply figures for tokenized US treasuries — I want to see how much BlackRock BUIDL, Circle USYC, and Ondo USDY are each circulating right now.

## When to prefer this

Choose this endpoint when you specifically need circulating supply data for tokenized US treasury or money market fund tokens (BUIDL, USYC, USDY). Prefer it over general DeFi TVL endpoints when the focus is on RWA treasury tokens rather than broader protocol TVL, and over the Realedger gold endpoint when the asset class is fixed-income/cash equivalents rather than commodities.

## Known failure modes

- DefiLlama data unavailability causing stale or missing supply figures
- Payment failure if x402 USDC payment of $0.10 is not included or rejected
- Rate limiting if too many calls are made in a short period
- Tokens with no on-chain activity may return zero or null supply values

## How this service works

## Output
