DefiLlama Data Aggregator

Professional DeFi data at your fingertips. Query TVL, protocols, chains, and yields from DefiLlama with a single command.

What This Skill Does

• TVL Query - Get total DeFi TVL or individual chain TVL
• Protocol Data - Query protocol details, rankings, and filter by category
• Chain Statistics - Get TVL for specific chains (Ethereum, Solana, etc.)
• Yield Pools - Find high-yield opportunities with filtering options
• Health Monitoring - Check API availability status

Quick Start

# Get total DeFi TVL
node {skillDir}/src/index.js defillama tvl

# Get protocol TVL
node {skillDir}/src/index.js defillama protocol --name aave

# Get top protocols by TVL
node {skillDir}/src/index.js defillama protocols --limit 10 --sort tvl --format table

# Get chain TVL
node {skillDir}/src/index.js defillama chain --name ethereum

# Find high-yield pools
node {skillDir}/src/index.js defillama yields --min-apy 10 --chain ethereum --limit 20

# Check API health
node {skillDir}/src/index.js health

Output Formats

All data commands support multiple output formats:

# Pretty format (default, human-readable)
node {skillDir}/src/index.js defillama tvl --format pretty

# JSON format (for scripts and parsing)
node {skillDir}/src/index.js defillama tvl --format json

# Table format (for quick overview)
node {skillDir}/src/index.js defillama protocols --limit 10 --format table

# CSV format (for spreadsheets)
node {skillDir}/src/index.js defillama protocols --limit 50 --format csv

Use Cases

For DeFi Investors

"Show me the top 10 lending protocols by TVL"
"Find yield pools on Ethereum with APY above 15%"
"What is the current TVL of Aave?"

For Data Analysts

"Export all protocols data to CSV"
"Get the TVL distribution across chains"
"Compare lending vs DEX TVL"

For Developers

"Check if DefiLlama API is healthy"
"Get protocol data in JSON format"
"Find pools with minimum 1M TVL"

Security Features

• Input Sanitization - All inputs validated and sanitized
• Error Filtering - API errors filtered to prevent information leakage
• Range Validation - Numeric inputs validated against bounds
• Pattern Validation - Protocol/chain names follow strict rules

Security Notes

• No API Keys Required: This skill uses DefiLlama's public API which does not require authentication
• External Requests: Data is fetched from:
  • https://api.llama.fi (DefiLlama API)
  • https://yields.llama.fi (DefiLlama Yields API)
• No Local Server: This skill does not start any local HTTP server
• No File Persistence: No data is persisted locally (caching is in-memory only)
• Input Validation: All user inputs are sanitized to prevent injection attacks

Installation

Prerequisites

• Node.js >= 16.0.0
• npm

Setup

cd {skillDir}
npm install

Error Handling

The skill provides user-friendly error messages:

Examples

Get Top Protocols

node {skillDir}/src/index.js defillama protocols --limit 10 --sort tvl --format table

Find High-Yield Pools

node {skillDir}/src/index.js defillama yields --min-apy 20 --min-tvl 1000000 --limit 5

Check Health

node {skillDir}/src/index.js health

Troubleshooting

Protocol Not Found

• Ensure the protocol name matches DefiLlama's naming (e.g., aave-v3 not aave v3)
• Check if the protocol is listed on DefiLlama

Chain Not Found

• Use lowercase chain names (e.g., ethereum not Ethereum)
• For multi-word chains, use hyphens (e.g., polygon-pos)

No Results from Yields

• Try lowering the --min-apy or --min-tvl thresholds
• Ensure the chain name is valid

Network Errors

• Check internet connectivity
• DefiLlama API may be temporarily unavailable
