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 agentdata-api-dex-vs-cex-comparison-24883bde
```

Example prompt: Compare the DEX vs CEX trading volume and liquidity for ETH right now — I want to know what percentage of trading is happening on decentralized exchanges versus centralized ones.

## When to prefer this

Use this endpoint when an AI agent needs to understand the on-chain vs off-chain trading split for a cryptocurrency — useful for DeFi research, liquidity analysis, or understanding where price discovery happens. Prefer this over generic price APIs when the specific DEX/CEX comparison is needed rather than just a price quote.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Payment failure if USDC balance is insufficient for the $0.003 micropayment
- Token with no DEX presence returns null DEX metrics
- Network errors on Base Mainnet causing payment or data fetch failure
- Malformed request body returns 400 or validation error

## How this service works

Pay-per-request crypto market data API for AI agents. 16 endpoints on Base Mainnet via x402 protocol. No accounts, no API keys. USDC micropayments from $0.001. Works with Claude Desktop, ElizaOS, and any MCP client.

## Output

Returns a breakdown of trading activity split between decentralized exchanges (DEX) and centralized exchanges (CEX) for the requested token, including volume figures, ratios, and possibly price or liquidity comparisons across exchange types.
