# DEX Volume & Chain Momentum Rankings via DefiLlama (x402)

> DEX Volume & Chain Momentum Rankings via DefiLlama (x402) 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 trading volume and TVL momentum data across blockchain chains, sourced from DefiLlama, payable per-call via x402 USDC micropayment.

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 dex-volume-chain-momentum-rankings-via-defillama-x402-7ad3c889
```

Example prompt: Pull the latest DEX volume and chain momentum rankings from DefiLlama — sorted by momentum — and focus on Base so I can see how it ranks against other chains by TVL and 7-day trading volume.

## When to prefer this

Choose this endpoint when an AI trading or onchain agent needs real-time DeFi chain rankings by DEX volume or TVL momentum, especially when no API key is available and micropayment via x402 USDC on Base is acceptable. Prefer it over full DefiLlama API integrations when you want a lightweight, pre-aggregated signal with momentum scoring rather than raw protocol-level data.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base is not included or insufficient
- Invalid 'sort' enum value returns validation error
- Invalid 'chain' string may return empty or unfiltered results
- DefiLlama upstream unavailability may cause stale or missing data
- Cached data up to 10 minutes old may not reflect very recent market moves

## 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

Returns a ranked list of blockchain chains with their DEX trading volumes (24h, 7d, 30d), TVL in USD, momentum scores, trend labels (GROWING/SHRINKING), TVL share percentages, volume-over-volume change rates, and a summary identifying the biggest, busiest, and fastest-growing chains. Also includes suggested next endpoints and a data freshness timestamp (10-minute cache).
