# DefiLlama DEX Summary — Cross-Chain Volume & TVL Momentum

> DefiLlama DEX Summary — Cross-Chain Volume & TVL Momentum is a paid API for AI agents from kr-x402-mvp.kgy5612.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Returns ranked DEX volume, TVL, and momentum scores across chains (e.g. Base, Solana, Ethereum) sourced from DefiLlama, with optional chain focus and sort order.

## Facts

- Endpoint: GET https://kr-x402-mvp.kgy5612.workers.dev/defillama/dex-summary?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/defillama-dex-summary-cross-chain-volume-tvl-momentum-87b0cfe8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Xnr9HQkmAFNcuGwEqJ4OO

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 defillama-dex-summary-cross-chain-volume-tvl-momentum-87b0cfe8
```

Example prompt: Show me the current DEX volume and TVL momentum rankings across chains — sorted by momentum — and highlight whether Base is growing or shrinking.

## When to prefer this

Choose this endpoint when an agent needs a multi-chain DeFi overview — comparing TVL, DEX volume trends, and momentum rankings across blockchains — especially when Base is a chain of interest. Prefer over single-chain APIs when the task is ranking or comparing chains. Best suited for trading agents, portfolio monitors, or strategy bots that need to identify which chains are growing or shrinking before making routing or allocation decisions.

## Known failure modes

- Invalid chain name returns empty focus or unfiltered list
- Invalid sort enum value may fall back to default (momentum) or return an error
- Data may be up to 10 minutes stale during cache window
- Payment failure via x402 (insufficient USDC balance or unsupported wallet) blocks the call
- Workers.dev endpoint may be unavailable during Cloudflare outages

## How this service works

Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.

## Output

A JSON object with a ranked list of chains, each showing TVL (USD), DEX volume over 24h/7d/30d, TVL change percentages, a momentum score and rank, trend label (GROWING/SHRINKING/FLAT), and a summary section calling out the biggest by TVL, busiest DEX, and fastest growing chain. Also includes suggested next endpoints and data freshness timestamp (10-minute cache).
