## 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 defi-protocols-by-tvl-2da2ef54
```

Example prompt: Pull the top 20 DeFi protocols ranked by total value locked from DefiLlama and show me their names, chains, and TVL figures.

## When to prefer this

Choose this endpoint when you need a ranked list of DeFi protocols by TVL sourced from DefiLlama without building your own aggregation logic. It is ideal for market overviews, competitor research, or any workflow needing up-to-date TVL rankings across multiple chains. Prefer this over raw DefiLlama API calls when you want a pay-per-use, agent-compatible interface at low cost ($0.005 per call).

## Known failure modes

- limit parameter out of range (below 1 or above 100) may return an error or default behavior
- DefiLlama API unavailability may cause stale or missing data
- Network timeout on Render.com cold start if service is idle
- Missing or malformed query parameter may return default 20 results

## How this service works

Top DeFi protocols ranked by TVL (total value locked), highest first, source DefiLlama. Optional parameter: ?limit=<n> (1 to 100, default 20).

## Output

Returns a JSON object containing a count of results, the source URL (DefiLlama API), a fetch timestamp, and an array of protocol objects each with name, chain, token symbol, TVL in USD, and category — sorted highest TVL first.
