## 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 baron-power-play-defi-markets-544364e0
```

Example prompt: Pull the latest DeFi market snapshot — I want to see which protocols are leading by TVL and what pairs are trending with their current prices and 24h volume.

## When to prefer this

Choose this endpoint when you need a no-account, no-subscription, pay-per-call DeFi market snapshot with both TVL rankings and trending pair data in a single call. Ideal for AI agents that need real-time DeFi intelligence without OAuth setup or monthly subscription overhead — just pay $0.002 USDC per query via x402 on Base.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient USDC balance
- Network timeout if Cloudflare Worker is cold-starting or overloaded
- Empty or stale data if upstream DeFi data sources are unavailable
- Malformed JSON response if underlying data aggregation fails
- Rate limit or block if caller IP is flagged by Cloudflare

## How this service works

Pay-per-call AI infrastructure for autonomous agents. USDC on Base, settled by Coinbase. No API key, no account, no subscription.

## Output

Returns a JSON object with two arrays: 'tvl_leaders' (list of DeFi protocols with name, TVL in USD, and 1-day percentage change) and 'trending_pairs' (list of token pairs with pair name, current price in USD, and 24h trading volume). No authentication required; costs $0.002 USDC per call settled on Base via x402.
