## 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 scriptmasterlabs-rwa-assets-api-19910db7
```

Example prompt: Pull me the first 10 tokenized treasury assets from the RWA assets listing — I want to see what tokenized treasuries are currently available.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001 USDC) programmatic lookup of tokenized real-world assets and want to filter by asset class such as tokenized treasuries. Prefer this over manual RWA research tools when you need structured, machine-readable asset listings for agent workflows, compliance checks, or portfolio aggregation. Not ideal if you need deeply detailed asset prospectuses or verified regulatory filings — this is a lightweight data listing API.

## Known failure modes

- Payment not settled — 402 response if USDC payment via x402 is not properly attached
- Invalid asset_class value returns empty results or error
- Limit parameter out of range may return default of 25 records
- Service hosted on Render free tier may have cold-start latency or occasional downtime
- Response schema is underspecified — fields may vary or be empty

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

A paginated list of real-world asset (RWA) records including asset identifiers, asset class labels (e.g. tokenized_treasuries), and associated metadata. The response schema is minimal and the exact fields returned depend on the live API data, but typically includes asset names, types, and on-chain identifiers. Each call is settled via x402 at $0.001 USDC on Base.
