## 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 cortexcloud-defillama-protocol-lookup-5014a3be
```

Example prompt: Look up the DeFiLlama protocol data for Uniswap — I want to know its current TVL, which chains it runs on, and any other available stats.

## When to prefer this

Use this endpoint when you need DeFiLlama protocol data on-demand without managing API keys or subscriptions, especially in agentic workflows that pay per call in USDC. Prefer this over direct DeFiLlama API access when operating in a pay-as-you-go crypto-native agent stack on Base.

## Known failure modes

- Unknown or misspelled protocol slug returns empty result or 404
- Payment failure on Base network causes 402 response and no data returned
- DeFiLlama data unavailable or stale for newly listed protocols
- Malformed request parameters result in error response
- Protocol exists but has no TVL data tracked by DeFiLlama

## How this service works

OpenAI-compatible AI and data API for agents. Pay per call in USDC on Base via x402 — no API keys, no subscriptions, no lock-in.

## Output
