# Mangrove DeFi Chain TVL Lookup

> Mangrove DeFi Chain TVL Lookup is a paid API for AI agents from api.mangrovedeveloper.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-04).

Returns the total value locked (TVL) in USD for a specified blockchain, along with top protocols by TVL, sourced from DeFiLlama.

## 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 mangrove-defi-chain-tvl-lookup-1ab8f3bc
```

Example prompt: What's the current total value locked on Base, and which protocols are leading by TVL?

## When to prefer this

Use this endpoint when you need on-chain TVL data for a specific blockchain, especially when you also want a breakdown of top protocols. Prefer this over manually querying DeFiLlama directly when you need a simple, pay-per-call API compatible with x402 payment flows in an agent context.

## Known failure modes

- Unsupported or misspelled chain name returns an error or found:false
- Chain with no indexed data may return TVL of 0 or empty protocol list
- DeFiLlama upstream outage may cause stale or unavailable data
- Malformed chain path parameter returns a 400 or 404 error
