# SiteCheck DeFi Fees Lookup

> SiteCheck DeFi Fees Lookup is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Returns fee and revenue statistics for a DeFi protocol (e.g. Aave, Uniswap) sourced from DefiLlama, including 24h, 7d, and 30d totals and day-over-day change percentages.

## Facts

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 sitecheck-defi-fees-lookup-06703900
```

Example prompt: What are the fees and revenue stats for Aave over the last 7 days — give me the 24h and 30d totals too, plus any day-over-day change?

## When to prefer this

Use this endpoint when you need structured, ready-to-use DeFi protocol fee and revenue metrics sourced from DefiLlama without building a direct DefiLlama integration. It is ideal for agents that need pay-per-call access to protocol analytics alongside other data types (web audits, compliance, blockchain) from a single multi-tool provider. Prefer this over direct DefiLlama API calls when using the SiteCheck ecosystem for other tasks.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or empty data
- DefiLlama upstream unavailability causes data fetch failure
- Protocol exists but has no fee data tracked by DefiLlama
- Missing required 'protocol' query parameter triggers validation error
- Rate limiting or payment failure (402) if USDC balance is insufficient

## How this service works

A DeFi protocol's fees and revenue for 24 hours, 7 days and 30 days, with the change over the last day against the day before, and the chains it runs on. Attribution: Data: DefiLlama. Information only, not financial advice.

## Output

A JSON object containing total fees (24h, 7d, 30d in USD) and their 1-day percentage change, protocol revenue figures (24h, 7d, 30d in USD) with 1-day change, a list of chains the protocol operates on, the protocol's canonical name, a source URL to the underlying DefiLlama data, a timestamp, and a disclaimer noting the data is informational only.
