# DeFi TVL Microdata API

> DeFi TVL Microdata API is a paid API for AI agents from kr-x402-mvp.kgy5612.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Returns total DeFi TVL with multi-period % changes, risk signal, top chains ranked by TVL, and optional per-chain or per-protocol breakdown in a single call.

## 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-tvl-microdata-api-a0772efe
```

Example prompt: What's the current DeFi risk signal and total TVL, and where does Base rank among the top 20 chains by TVL share?

## When to prefer this

Choose this endpoint when an AI agent needs DeFi TVL, chain rankings, capital flow signals, and risk sentiment in a single $0.002 call — instead of buying separate TVL and DeFi overview calls from other providers. Ideal for trading agents, portfolio monitors, or any workflow that needs a fast, cheap, structured DeFi health check without assembling data from multiple sources. Also prefer when you need Base-specific TVL context or a DefiLlama-backed protocol TVL figure (e.g. Aave, Lido, Uniswap, Aerodrome).

## Known failure modes

- Invalid chain name returns no chain block or error
- Invalid protocol slug returns no protocol block
- limit out of range (1-50) causes validation error
- DefiLlama upstream unavailability may cause stale or missing data
- Payments via x402 failing due to insufficient USDC balance block the request entirely

## How this service works

DeFi TVL in ONE call (others sell TVL and DeFi overview as two $0.003 calls): total DeFi TVL with 1d/7d/30d % change and flow inflow|flat|outflow, signal RISK_ON|NEUTRAL|RISK_OFF, top chains ranked by TVL with share %, Base rank+share; chain=Base|Ethereum|Solana|... adds that chain's TVL, rank, share and 1d/7d/30d flow; protocol=aave|lido|uniswap|aerodrome (DefiLlama slug) adds protocol TVL and share. limit=1-50 top chains (default 15).

## Output

A JSON object containing: total DeFi TVL in USD with 1d/7d/30d % changes and flow direction; a macro risk signal (RISK_ON, NEUTRAL, or RISK_OFF) with human-readable reasons; a ranked list of top chains (up to 50) with name, TVL, and share %; optionally a per-chain breakdown (TVL, rank, share, flow, chain_id, as_of) and/or a per-protocol breakdown (TVL, share); a Base-specific summary; data source URL; and an updated_at timestamp.
