## 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 tanod-chainpeek-protocol-fees-revenue-8db42e4f -d '<json body>'
```

Example prompt: What are Aave's fees and revenue over the last 24 hours, 7 days, and 30 days? Pull the latest data from DefiLlama.

## When to prefer this

Use this endpoint when an agent needs to assess a DeFi protocol's economic activity — specifically fees generated and revenue retained — across multiple time horizons. Prefer it over raw on-chain queries when pre-aggregated, multi-period data from DefiLlama is sufficient and speed matters. It is especially useful for investment research, protocol comparison, or monitoring fee trends without building a custom data pipeline.

## Known failure modes

- Unknown protocol name returns HTTP 422 with a list of suggested protocol slugs
- Empty or whitespace-only protocol name rejected by schema validation
- Stale cache may lag real-time on-chain fee events
- Parent protocol aggregates child versions which may cause unexpected totals

## How this service works

chainpeek (Tanod) protocol fees and revenue over 24 hours to all time, from cached DefiLlama data. Use when an agent must judge what a protocol earns: its fees and revenue over 24 hours, 7 days, 30 days and a year.

## Output

Returns a structured breakdown of the protocol's fees and revenue for 24h, 7d, 30d, and all-time periods. Data is cached from DefiLlama. An unknown protocol name returns a 422 error with suggested valid alternatives.
