# Heurist Mesh: DefiLlama Chain Metrics Agent

> Heurist Mesh: DefiLlama Chain Metrics Agent 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 blockchain-level DeFi metrics including TVL, fees, top protocols by fees, and growth trends for a specified chain via DefiLlama data.

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-defillama-chain-metrics-agent-a6ffad0f -d '<json body>'
```

Example prompt: What's the current TVL, total fees, and top protocols by fees on Solana, and how has it been trending recently?

## When to prefer this

Use this endpoint when you need aggregated, chain-level DeFi statistics (TVL, fees, protocol rankings, growth trends) for a specific blockchain. Prefer this over wallet-level or token-level endpoints when the goal is ecosystem-wide analysis. It is best suited for macro DeFi research, chain comparison, or investment due diligence — not for individual wallet analysis or token price lookups.

## Known failure modes

- Unsupported or misspelled chain name returns an error or empty result
- DefiLlama data unavailable or stale for niche chains
- Rate limiting or payment failure with x402 protocol returns 402 status
- Chain with very low DeFi activity may return sparse or zero-value metrics

## How this service works

Get metrics for a blockchain including TVL, fees, top protocols by fees, and growth trends.

## Output

Returns structured DeFi metrics for the specified blockchain, including total value locked (TVL), total fees, a ranked list of top protocols by fee generation, and chain-level growth trend data — all sourced from DefiLlama.
