# RWA Protocol Ranking by On-Chain TVL

> RWA Protocol Ranking by On-Chain TVL is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-11).

Returns a ranked list of tokenized real-world asset protocols (treasury bills, private credit, gold, real estate, etc.) by on-chain TVL, with 7-day change, chain count, token, and total RWA market size, sourced from DefiLlama.

## 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-protocol-ranking-by-on-chain-tvl-33b669e3 -d '<json body>'
```

Example prompt: Give me the top 10 tokenized real-world asset protocols ranked by on-chain TVL right now, including their 7-day change and which chains they're on.

## When to prefer this

Choose this endpoint when you need a live, ranked leaderboard of tokenized real-world asset protocols by on-chain TVL with recent performance metrics. It is ideal for DeFi dashboards, RWA market research, investment monitoring, or any agent workflow that needs structured, up-to-date RWA data without scraping DefiLlama directly. Prefer it over general DeFi TVL endpoints when the user's question is specifically about tokenized real-world assets (treasuries, private credit, gold, real estate) rather than DeFi protocols broadly.

## Known failure modes

- Invalid or missing 'input' object returns a validation error
- Non-integer value for 'limit' field causes schema rejection
- DefiLlama data may be delayed or unavailable during upstream outages, potentially returning stale or empty data
- Very high limit values may return null entries for protocols with incomplete data
- Payment failure (insufficient USDC balance) blocks the request entirely

## How this service works

Ranking of tokenized real-world asset protocols (treasury bills, private credit, gold, real estate...) by on-chain value, with 7-day change, chains and token, plus total RWA value. DefiLlama data.

## Output

Returns a JSON object with a ranked array of RWA protocols, each including protocol name, token symbol (if any), TVL in USD, market share percentage, 1-day and 7-day change percentages, and chain count. Also includes total RWA TVL across all tracked protocols and the total number of protocols. Data is sourced from DefiLlama and excludes stablecoins.
