## 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 saylor-innovations-defi-protocol-tvl-10f1eec9
```

Example prompt: What's the current Total Value Locked for Uniswap — can you pull the TVL data for the 'uniswap' protocol slug?

## When to prefer this

Use this endpoint when you need TVL data for a specific known DeFi protocol by its slug identifier, especially within an agentic workflow that already uses Saylor Innovations' DeFi data suite. It's best for point-in-time lookups of a single protocol rather than broad market comparisons.

## Known failure modes

- Invalid or unrecognized protocol slug returns a 404 or empty result
- Protocol slug must be exact — misspellings yield no data
- Data may be delayed if upstream DeFi data sources are lagging
- Rate limiting or payment failure (x402) if USDC balance is insufficient

## How this service works

DeFi Protocol TVL. DeFi protocol TVL: total value locked, 1-day and 7-day change, per-chain TVL with borrowed and staked amounts, category, market cap and audit count for any DefiLlama protocol slug.

## Output

Returns TVL data for the specified DeFi protocol including the total value locked figure (typically in USD), associated with the protocol identified by the slug parameter.
