## 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 scrapling-x402-defi-protocol-lookup-9056b6b5
```

Example prompt: What is the current TVL and 7-day change for Aave? Look it up by its DefiLlama slug.

## When to prefer this

Choose this endpoint when you need quick, structured TVL and performance data for a specific DeFi protocol by name or DefiLlama slug, especially in agent workflows that pay per call via x402 micropayments. Prefer over scraping DefiLlama directly when you need a pay-as-you-go, agent-friendly API with structured JSON output.

## Known failure modes

- Unknown or misspelled protocol slug returns empty or error response
- Protocol not indexed by DefiLlama returns no results
- Missing required 'q' query parameter returns a validation error
- Payment not settled correctly via x402 returns HTTP 402 without data
- Rate limiting or upstream DefiLlama outage causes failure

## How this service works

DeFi protocol TVL and trend: total value locked in USD, 1d/7d TVL % change, category, chains and token market cap (DefiLlama data). Example: q=aave, q=uniswap, q=lido. Refreshed about every 30 min

## Output

Returns a JSON object with the protocol's canonical name, its DefiLlama slug, current TVL in USD, and the 7-day percentage change in TVL. Example: {name: 'Aave', slug: 'aave', tvl_usd: 25000000000, change_7d_pct: 3.1}.
