## 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-protocols-ce8ea17e
```

Example prompt: Pull the full list of DeFi protocols from DeFiLlama so I can see their names, chains, and total value locked — pay the $0.005 call fee in USDC.

## When to prefer this

Choose this endpoint when you need a comprehensive, up-to-date list of DeFi protocols and their TVL metrics sourced from DeFiLlama, without requiring an API key or subscription — ideal for AI agents that pay per call in USDC via x402 on Base. Prefer this over direct DeFiLlama API access when you want no-key, micropayment-based access, or when integrating into an x402-compatible agent payment flow.

## Known failure modes

- Payment failure: x402 USDC payment not completed or insufficient balance, returning 402 Payment Required
- Network/upstream error: DeFiLlama API unavailable, resulting in 503 or timeout
- Malformed properties filter: invalid query parameter format returns 400 Bad Request
- Empty response: no protocols match the applied filter criteria

## 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
