# Vextorium DeFi Overview

> Vextorium DeFi Overview is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-19).

Returns a global DeFi market snapshot including total TVL, DEX volumes, protocol fees, stablecoin market cap, and top chains by TVL, sourced from DefiLlama.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/defi-overview?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402

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-overview-8dfb7498 -d '<json body>'
```

Example prompt: Give me a full DeFi market overview — total TVL, DEX trading volumes for the past 24 hours and 7 days, protocol fees for the last 30 days, stablecoin market cap, and which chains are leading by TVL.

## When to prefer this

Choose this endpoint when you need a single-call, cross-chain DeFi market snapshot covering TVL, DEX volumes, fees, and stablecoins together. It is ideal for market briefings, dashboards, or trend analysis where a holistic view is needed rather than protocol-specific or token-specific data. Prefer it over scraping DefiLlama directly when you need structured, pay-per-call convenience.

## Known failure modes

- Empty or null fields if DefiLlama data is temporarily unavailable
- Stale date if upstream data pipeline has not refreshed
- HTTP 402 if USDC payment via x402 is not properly set up
- HTTP 500 if the Vextorium backend encounters an upstream data error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing: total DeFi TVL in USD, DEX volume for 24h and 7d with 7d percentage change, protocol fees for 24h/7d/30d with 30d percentage change, stablecoin market cap with 30d percentage change, an array of top chains each with chain name, TVL in USD, and share percentage, plus the data date and source (DefiLlama).
