# RWA (Real-World Assets) On-Chain Overview

> RWA (Real-World Assets) On-Chain Overview is a paid API for AI agents from micro-saas-agent.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-19).

## 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 rwa-real-world-assets-on-chain-overview-55f78d9f
```

Example prompt: Give me a full breakdown of the top real-world asset protocols on-chain right now — TVL rankings, 7-day movers, any newly listed protocols from the last month, the best RWA yield pools, and top RWA tokens by market cap.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-faceted snapshot of the RWA on-chain market in a single call — covering TVL rankings, movers, new listings, yield pools, and token market caps simultaneously. It is ideal for research, market monitoring, or generating investment overviews. Prefer it over manual DefiLlama/CoinGecko queries when you want pre-aggregated, RWA-specific data with a 10-minute cache at very low cost ($0.02).

## Known failure modes

- Upstream DefiLlama or CoinGecko API unavailability may result in stale or partial data
- Cache may be up to 10 minutes old, so very recent market moves may not be reflected
- Payment of $0.02 USDC required via x402; missing or invalid payment returns 402 error
- Empty result sets if no newly listed protocols exist in the 30-day window

## How this service works

Real-world assets on-chain: top RWA protocols by TVL with 1d/7d change and estimated 7d flows, 7d movers, protocols newly listed in the last 30 days, top RWA yield pools, top RWA tokens by market cap, plus sources, per-source status and timestamp. Public DefiLlama + CoinGecko data, 10-min cache. $0.02.

## Output

A structured JSON snapshot containing: top RWA protocols ranked by TVL with 1-day and 7-day percentage changes and estimated 7-day capital flows; 7-day TVL movers (biggest gainers/losers); protocols newly listed in the last 30 days; top RWA yield pools with APY data; top RWA tokens by market cap; and per-source status and cache timestamps from DefiLlama and CoinGecko.
