## 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 market-dex-volumes-api-fa1a44b2
```

Example prompt: What's the total decentralized exchange trading volume over the last 24 hours, and which DeFi protocols like Uniswap V3 are leading by market share?

## When to prefer this

Use this endpoint when you need a quick, aggregated snapshot of 24-hour DEX trading volumes broken down by protocol with market share percentages. Prefer it over raw on-chain queries when you want pre-aggregated, human-readable DeFi volume data without building your own aggregation logic. It is well-suited for dashboards, research reports, or automated DeFi monitoring agents that need periodic volume checks.

## Known failure modes

- Missing or malformed properties parameter may return empty or unexpected results
- Data may be delayed or stale if upstream aggregation sources are unavailable
- Non-200 responses if payment (x402 micropayment) is not correctly attached
- Rate limiting or payment failure returning 402 Payment Required

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output

Returns a JSON object with the total 24-hour DEX volume (e.g. $9.8B) and an array of protocol entries, each containing the protocol name, URL slug, its individual 24h volume, and percentage share of the total market.
