# DeFi Protocol TVL with Per-Chain Breakdown

> DeFi Protocol TVL with Per-Chain Breakdown is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

Returns total value locked for any DeFi protocol with per-chain breakdown and 7-day change, revealing protocol size, momentum, and chain concentration.

## Facts

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 defi-protocol-tvl-with-per-chain-breakdown-a541bf1c
```

Example prompt: What's the current TVL for Uniswap, broken down by chain, and how has it changed over the last 7 days?

## When to prefer this

Use this endpoint when you need current TVL data for a specific DeFi protocol with chain-level granularity and recent momentum (7-day change). Prefer this over generic DeFi dashboards when programmatic, per-call access is needed by an AI agent assessing protocol health, capital flow direction, or chain concentration in an automated workflow.

## Known failure modes

- Unknown or misspelled protocol name returns an error or empty result
- Protocol not indexed by the data source returns null TVL
- Rate limiting or payment failure returns 402 or 429 status
- Data freshness lag may cause stale TVL figures for rapidly changing protocols
- Protocol with very low TVL may show zero or incomplete chain breakdown

## How this service works

Total value locked for any DeFi protocol with per-chain breakdown and 7-day change - shows a protocol's size, momentum and which chains it is concentrated on, for agents assessing protocol health and capital flows. protocol tvl, defi tvl, total value locked, protocol size, tvl by chain, protocol momentum, defi protocol stats Accepts payment on Base or Solana — either network works.

## Output

Returns the protocol's aggregate total value locked in USD, a breakdown of TVL per blockchain (e.g. Ethereum, Arbitrum, Optimism), and the 7-day percentage or absolute change in TVL, enabling assessment of protocol size, growth momentum, and chain concentration.
