## 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 defi-protocol-tvl-lookup-defillama-via-task-radar-x402-9759b3c0
```

Example prompt: What's Aave's current TVL, how has it changed over the last day and week, and how is it split across chains?

## When to prefer this

Choose this endpoint when you need real-time TVL data for a specific DeFi protocol including recent trend data (1d/7d changes) and multi-chain distribution, without setting up your own DefiLlama integration. Ideal for agents building DeFi dashboards, risk monitors, or investment research tools that need per-chain granularity alongside aggregate TVL figures.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or empty result
- DefiLlama upstream API outage causes unavailability
- Protocol not indexed by DefiLlama returns no data
- Payment not received results in 402 response before data is returned
- Rate limiting if too many calls are made in quick succession

## How this service works

DeFi protocol TVL now, 1d/7d change and per-chain split (DefiLlama). 0.02 USDC/call on Base.

## Output

Returns the protocol's current total TVL in USD, the absolute or percentage change over the past 1 day and 7 days, and a breakdown of TVL allocated to each blockchain where the protocol is deployed — all sourced from DefiLlama.
