## 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-solana-rwa-supply-5a25d0b0
```

Example prompt: What does Realedger show for BUIDL's supply on Solana right now, and what percentage of its total known cross-chain supply does that represent?

## When to prefer this

Use this endpoint when you need Solana-specific, SPL-mint-verified (grade A) supply figures for stablecoins and tokenized treasuries, especially when cross-chain share breakdown is needed. Prefer it over general DeFi aggregators when data provenance and on-chain verification matter. It is cheap and pollable, making it suitable for high-frequency monitoring. Choose sibling Ethereum endpoint instead if you need Ethereum contract-sourced treasury data.

## Known failure modes

- Network or API unavailability returns an HTTP 5xx error
- Payment not received or x402 auth failure results in 402 Payment Required
- Malformed query parameters may return 400 Bad Request
- Newly listed assets may not yet appear in the rows object
- Solana RPC congestion could delay freshness of on-chain reads

## How this service works

Weekly scoreboard grading tokenized RWA promises against verified on chain reality. Every number carries an evidence grade and a retrieval timestamp; the archive is append only.

## Output

A JSON object with a 'realedger' key containing 'rows' (per-ticker entries with solana_supply in token units and solana_share_of_known_pct as a percentage) and 'value' (total USD notional of tracked RWAs on Solana). Supply data is grade A, sourced directly from SPL mint contracts.
