# EMC2 AI DEX Capital Concentration Analyzer

> EMC2 AI DEX Capital Concentration Analyzer is a paid API for AI agents from emc2ai.io, paid per call via x402, $1/call, status unknown (last checked 2026-09-13).

Analyzes capital concentration across DEX protocols on multiple chains, revealing how liquidity and trading volume are distributed across different decentralized exchanges.

## Facts

- Endpoint: POST https://emc2ai.io/x402/bitquery/dexcapital
- Price: $1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 emc2-ai-cd7850bf -d '<json body>'
```

Example prompt: Show me which DEX protocols have the highest capital concentration on Arbitrum right now — I want to see where the big money is pooled across decentralized exchanges.

## When to prefer this

Use this endpoint when you need to understand macro-level DEX market structure — which protocols dominate liquidity on a specific chain. Prefer this over token-specific or wallet-specific endpoints when the question is about protocol-level capital flows and DEX market share rather than individual trader behavior or token performance.

## Known failure modes

- Unsupported chain specified returns an error or empty result
- Invalid time period parameter causes malformed request
- Rate limiting or payment failure (x402) blocks the call
- Chain with low DEX activity may return sparse or incomplete data
- Network congestion on target chain may delay data freshness

## How this service works

Analyze capital concentration across different DEX protocols. Supported chains: bsc, base, ethereum, arbitrum, polygon, optimism, zksync. Default chain: base. Required params: none (chain/limit/timeperiod are optional and defaulted).

## Output

Returns a breakdown of capital concentration across DEX protocols on the requested chain, including metrics showing how trading volume and liquidity are distributed — identifying dominant DEXes and their relative share of on-chain capital.
