## 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 xynaptic-crypto-defi-protocol-health-5f5c8b16
```

Example prompt: What's the current TVL for Aave, how much has it changed in the last 24 hours, and which chains is it deployed on?

## When to prefer this

Use this endpoint when you need a fast, single-call summary of a DeFi protocol's on-chain health — specifically TVL, recent trend, chain distribution, and category — without needing to integrate directly with DefiLlama. Ideal for agents building DeFi dashboards, monitoring protocol growth, or enriching research reports. Prefer this over raw DefiLlama API access when you want a pre-packaged, pay-per-call result without API key management.

## Known failure modes

- Unknown or misspelled protocol name returns no data or an error
- Protocol not indexed by DefiLlama returns empty result
- Missing required ?protocol= query parameter causes a 400 or error response
- DefiLlama data source lag may cause slightly stale TVL figures
- Network or upstream API timeout if DefiLlama is unavailable

## How this service works

Xynaptic Crypto DeFi — protocol health in one call: current TVL, 24h change, chain breakdown, category. Parameter: ?protocol=aave. DefiLlama data.

## Output

Returns a structured snapshot of the specified DeFi protocol including: current total value locked (TVL) in USD, percentage or absolute 24-hour TVL change, TVL broken down by blockchain/chain, and the protocol's DeFi category (e.g. lending, DEX, liquid staking).
