# Heurist Mesh: DeFi Protocol Metrics via DefiLlama

> Heurist Mesh: DeFi Protocol Metrics via DefiLlama is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Retrieves DeFi protocol metrics including TVL, fees, volume, revenue, deployed chains, and growth trend from DefiLlama data for a given protocol slug.

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 heurist-mesh-defi-protocol-metrics-via-defillama-98fb8efb -d '<json body>'
```

Example prompt: Can you pull up the DeFi metrics for Uniswap — I want to see its TVL, fees, volume, revenue, and which chains it's deployed on? The DefiLlama slug is 'uniswap'.

## When to prefer this

Use this endpoint when you need structured on-chain DeFi protocol analytics (TVL, fees, revenue, volume, chain coverage) sourced from DefiLlama. Prefer it over general web search when you need numeric, machine-readable protocol metrics rather than narrative summaries. It is particularly suited for comparing DeFi protocols, tracking growth trends, or building DeFi research reports where DefiLlama slugs are known.

## Known failure modes

- Invalid or unknown DefiLlama slug returns an error or empty result
- Protocol not indexed by DefiLlama returns no data
- Network timeout or upstream DefiLlama API unavailability
- Payment failure if USDC balance is insufficient for the $0.003 fee
- DEX-specific fields like volume absent for non-DEX protocols

## How this service works

Get metrics for a DeFi protocol including TVL, fees, volume (for DEXes), revenue, deployed chains, and growth trend. Use this tool when you want to analyze a DeFi project. You must input the defillama slug obtained from project knowledge base.

## Output

Returns structured metrics for the requested DeFi protocol including TVL (total value locked), generated fees, trading volume (for DEXes), protocol revenue, list of deployed blockchain networks, and a growth trend indicator derived from DefiLlama data.
