## 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-aa401ce5
```

Example prompt: Pull me up to 10 tokenized treasury assets from the ScriptMasterLabs RWA Assets API — I want to see what tokenized treasuries are available on-chain right now.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to tokenized real-world asset data (especially tokenized treasuries or similar asset classes) and want micro-payment settlement in USDC on Base via x402. It is well-suited for agents that need on-chain-compatible RWA discovery without a subscription or API key, paying only $0.001 per query.

## Known failure modes

- Invalid asset_class value returns empty or error response
- Payment failure via x402 if USDC balance is insufficient on Base
- Service unavailable if the Render-hosted instance is cold or sleeping
- Limit parameter out of expected range may return default or error
- Empty result set if no assets match the specified asset_class filter

## 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

Returns a paginated list of real-world asset (RWA) records, optionally filtered by asset class (e.g. tokenized_treasuries). Each record contains asset metadata relevant to on-chain tokenized assets. The response schema is minimal and the exact fields are dynamically defined by the provider.
