# Vextorium DeFi Protocol Overview

> Vextorium DeFi Protocol Overview is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-01).

Returns live TVL, TVL change percentages (1d/7d), category, supported chains, native token, and description for any DeFi protocol by name, sourced from DefiLlama.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vextorium-defi-protocol-overview-282c7aef -d '<json body>'
```

Example prompt: What's the current TVL for Lido, and how has it changed over the past week? Also tell me which chains it runs on and what its native token is.

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of a DeFi protocol's key metrics — TVL, TVL momentum, chain coverage, and token — without building a DefiLlama integration yourself. Ideal for research agents, DeFi dashboards, or portfolio monitoring workflows that need live protocol data by name. Prefer it over direct DefiLlama API calls when you want a paid, agent-friendly wrapper that works over x402.

## Known failure modes

- Unknown or misspelled protocol name returns null or error — use the exact DefiLlama slug (e.g. 'aave', 'uniswap-v3')
- Protocol with no DefiLlama entry returns empty or partial data
- Temporary DefiLlama API downtime may cause stale or missing TVL values
- TVL change fields may be null for newly listed or inactive protocols

## How this service works

Overview of any DeFi protocol by name (Aave, Uniswap, Lido, Pendle...): total value locked, 1d/7d/1m TVL change, category, chains it runs on, native token and description. Live from DefiLlama.

## Output

Returns a JSON object with the protocol's name, total value locked in USD, percentage TVL change over 1 day and 7 days, DeFi category (e.g. DEX, lending, liquid staking), list of supported chains, native token ticker, a short description, and links to the protocol's website, Twitter, and DefiLlama page. Some fields may be null if not available.
