## 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 market-intelligence-api-tokenized-treasuries-supply-issuance-e311c316
```

Example prompt: Pull the latest on-chain supply and 24h/7d issuance data for tokenized treasury funds like BUIDL and USYC, and tell me whether the market is currently risk-on or risk-off.

## When to prefer this

Choose this endpoint when you need a fast, on-chain-sourced risk sentiment signal specifically tied to tokenized US Treasury fund flows (BUIDL, OUSG, USDY, USTB, USYC). It is ideal for pre-trade risk checks in DeFi/RWA contexts, daily macro briefings incorporating on-chain capital flows, or monitoring institutional appetite for tokenized safe-haven assets. Prefer it over generic crypto sentiment endpoints when the question is specifically about real-world asset (RWA) fund issuance and not price action or order-book signals.

## Known failure modes

- Network or upstream on-chain RPC failure returns 5xx error
- Payment not received or x402 authorization missing returns 402 Payment Required
- Rate limiting if too many calls in a short window (429 Too Many Requests)
- Stale on-chain data if blockchain indexer is lagging, potentially returning outdated supply figures
- Empty or partial funds array if specific chain data is temporarily unavailable

## How this service works

Tokenized treasuries and RWA flows: supply and 24h/7d net issuance of tokenized treasury funds (BlackRock BUIDL, Ondo USDY and OUSG, Superstate USTB, Hashnote USYC) read on chain. Use as a risk-on/risk-off gauge from on-chain treasuries.

## Output

A JSON object containing an array of tokenized treasury funds (each with issuer name, symbol, supply in tokens, 24h percent change, and 7d percent change), an aggregate 24h percent change across all funds, and a top-level risk gauge string (e.g. NEUTRAL, RISK-ON, RISK-OFF) indicating overall market sentiment derived from net issuance flows.
