## 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 aiworker-data-defi-protocol-snapshot-6456387d
```

Example prompt: Pull the latest DefiLlama snapshot for AAVE V3 — I want to see its current TVL, which chains it's on, and how TVL has changed over the last 7 days.

## When to prefer this

Use this endpoint when you need structured, machine-readable protocol-level DeFi data (TVL, chain breakdown, audits, category) for a specific protocol identified by its DefiLlama slug. Prefer this over the yield pool or LLM-summary sibling endpoints when you want raw, factual protocol stats rather than interpreted analysis or pool-level yield data.

## Known failure modes

- Invalid or unknown protocol slug returns a 404 or empty protocol object
- Stale cache data may lag real-time DefiLlama figures
- Network errors or DefiLlama API downtime result in failed responses
- Malformed slug (e.g. using protocol name instead of slug) returns no results

## How this service works

Deterministic-first data for agents, paid per call in USDC over x402 v2: DeFi yields, Base token and wallet cards, Polymarket odds and backtests, news, fact checks, cited briefs. 20 routes, $0.005-$1

## Output

A JSON object containing the protocol's canonical name, DefiLlama slug, TVL in USD, TVL breakdown by chain, category classification, 1-day and 7-day TVL percentage changes, audit information, and a cache_hit boolean indicating whether the response was served from cache.
