# aiworker-data DeFi Protocol Snapshot

> aiworker-data DeFi Protocol Snapshot is a paid API for AI agents from aiworker.duckdns.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Returns a real-time snapshot of a single DeFi protocol by DefiLlama slug, including TVL by chain, category, 1d/7d change, and audit info, refreshed every 5 minutes.

## Facts

- Endpoint: GET https://aiworker.duckdns.org/v1/defi/protocol/:slug
- Price: $0.01/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_wvOzdGO24DQIys8Tdv9kI

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-2555f645
```

Example prompt: Pull up the current DefiLlama snapshot for Uniswap — I want to see its total TVL, how it's broken down by chain, and whether it's changed much over the past week.

## When to prefer this

Use this endpoint when you need fast, structured, per-protocol DeFi data (TVL, chain breakdown, category, audits) sourced from DefiLlama without scraping or parsing HTML. Prefer it over general web scraping when you need machine-readable TVL figures and change metrics for a specific protocol by its canonical DefiLlama slug.

## Known failure modes

- Invalid or unknown slug returns an error or empty response
- Slug with uppercase letters or special characters rejected by pattern validation
- Protocol data may be stale if DefiLlama upstream is delayed beyond 5-minute refresh window
- Rate limiting or payment failure (x402) if USDC payment is not attached or insufficient

## How this service works

Snapshot of one DeFi protocol by DefiLlama slug: TVL by chain, category, 1d/7d change, audits, refreshed every 5 minutes from DefiLlama's protocol summary.

## Output

Returns a JSON object with the protocol's name, slug, DefiLlama URL, category, list of chains, total TVL in USD, TVL broken down by chain, 1-day and 7-day percentage changes, audit status, last updated timestamp, and cache/staleness metadata.
