# DeFi Oracle TVL Tracker

> DeFi Oracle TVL Tracker is a paid API for AI agents from oraclius.vercel.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Fetches current TVL, 30-day TVL history, and protocol metadata for a given DeFi protocol by slug, powered by DeFiLlama data

## Facts

- Endpoint: POST https://oraclius.vercel.app/api/tvl-tracker
- Price: $0.05/call
- Payment: x402
- Status: unknown

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-oracle-tvl-tracker-82fc203d -d '<json body>'
```

Example prompt: What's the current TVL for Aave and how has it changed over the last 30 days — pull the full history too.

## When to prefer this

Use this endpoint when you need protocol-level TVL data including historical 30-day trends and chain breakdowns for a specific DeFi protocol. Prefer this over generic DeFi APIs when you need DeFiLlama-sourced TVL with percentage change metrics and multi-chain coverage in a single call, paid via USDC micropayment on Base.

## Known failure modes

- Invalid or unrecognized protocol slug returns an error or empty result
- Protocol not indexed by DeFiLlama returns no data
- Chain filter doesn't match any supported chains for the protocol
- Network or RPC data source timeout causes delayed or failed response
- Malformed request body missing required 'protocol' field returns a 400-level error

## How this service works

DeFi data for AI agents — yield rates, swap routes, IL calculator, liquidation risk, MEV scanner, TVL tracking. Powered by DeFiLlama + on-chain RPC data. Pay with USDC on Base via x402.

## Output

Returns a JSON object with the protocol's slug, display name, category, list of supported chains, current TVL in USD, 30-day percentage change in TVL, and an array of historical TVL data points over the past 30 days.
