DeFiLlama API is Great, But Here Are 5 Alternatives Worth Knowing

Let me get this out of the way upfront: DeFiLlama's API is excellent. It's free, open-source, and covers TVL data for virtually every DeFi protocol in existence. If you're building something that needs TVL numbers, DeFiLlama should probably be your first stop.

But it's not the only game in town. Depending on what you're building, you might need data that DeFiLlama doesn't provide — like yield rates, protocol categorization, or a unified API key system. That's where DeFi data API free alternatives come in.

In this article, I'll walk you through five DeFiLlama alternatives, what each one excels at, and when you should consider using them. Every entry includes a working Python example.

What DeFiLlama Does Well (And Where It Falls Short)

Before we look at alternatives, let's be fair about DeFiLlama's strengths:

Strengths:

  • Comprehensive TVL coverage across 2,000+ protocols
  • Completely free, no API key required
  • Open-source with active development
  • Historical TVL data
  • Clean, well-documented API

Limitations:

  • Yield/APY data is limited compared to TVL data
  • No built-in API key management or usage tracking
  • Protocol metadata (categories, audits, chains) could be richer
  • No dedicated support tier for production use cases
  • Rate limiting can be aggressive during peak times

If any of those limitations hit close to home, keep reading.

1. DeFi Data API (RapidAPI)

The DeFi Data API is one of the newer entrants, and it takes a different approach from DeFiLlama. Instead of being open-source and keyless, it runs through RapidAPI's infrastructure, which means you get API key management, usage analytics, and guaranteed uptime SLAs.

What sets it apart is the breadth of data. You get seven endpoints covering protocols, yields, chains, categories, and global stats — all from one base URL.

import requests

headers = {
    "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",
    "X-RapidAPI-Host": "defi-data-api"
}
base_url = "https://defi-api-425658670453.europe-west1.run.app"

# Get top yields across all of DeFi
response = requests.get(f"{base_url}/yields/top", headers=headers)
top_yields = response.json()

for pool in top_yields[:5]:
    print(f"{pool['symbol']} — {pool['apy']}% APY — ${pool['tvlUsd']:,.0f} TVL")
Enter fullscreen mode Exit fullscreen mode

Best for: Developers who want a single API for yields, TVL, and protocol data with RapidAPI's developer experience. The free tier is solid for side projects.

Where to find it: Search "DeFi Data API" on RapidAPI.

2. CoinGecko API

CoinGecko isn't a DeFi-specific API, but it's an essential part of any DeFi developer's toolkit. It provides token prices, market data, trending coins, and exchange information.

import requests

# Get top DeFi tokens by market cap
response = requests.get(
    "https://api.coingecko.com/api/v3/coins/categories",
    params={"category_order": "market_cap_desc"}
)

categories = response.json()
defi_cat = next((c for c in categories if c.get("id") == "decentralized-finance-defi"), None)

if defi_cat:
    print(f"DeFi Market Cap: ${defi_cat.get('market_cap', 0):,.0f}")
    print(f"24h Volume: ${defi_cat.get('volume_24h', 0):,.0f}")
Enter fullscreen mode Exit fullscreen mode

Best for: Price data, market cap rankings, and general crypto market context. Pairs well with a DeFi-specific API.

Limitation: Free tier has strict rate limits (10-30 calls/minute). The paid tier is expensive for indie developers.

3. The Graph

The Graph is fundamentally different from the other APIs on this list. Instead of REST endpoints, you write GraphQL queries against protocol-specific subgraphs. This gives you deep on-chain data access.

import requests

# Query Aave's subgraph for lending pool data
query = """
{
  pools(orderBy: totalLiquidity, orderDirection: desc, first: 5) {
    id
    underlyingAsset {
      symbol
      name
    }
    totalLiquidity
    variableBorrowRate
    liquidityRate
  }
}
"""

response = requests.post(
    "https://api.thegraph.com/subgraphs/name/aave/protocol-v3",
    json={"query": query}
)

for pool in response.json()["data"]["pools"]:
    asset = pool["underlyingAsset"]["symbol"]
    borrow_rate = int(pool["variableBorrowRate"]) / 1e25
    supply_rate = int(pool["liquidityRate"]) / 1e25
    print(f"{asset}: Borrow {borrow_rate:.2f}% | Supply {supply_rate:.2f}%")
Enter fullscreen mode Exit fullscreen mode

Best for: Granular, protocol-specific on-chain data. If you need to know the exact state of a lending pool or DEX pair, The Graph is unmatched.

Limitation: You need to learn GraphQL and understand each protocol's schema. Not ideal for cross-protocol comparisons.

4. Moralis Web3 API

Moralis provides a broader Web3 API that covers wallet activity, NFTs, token balances, and DeFi positions. It's less about raw protocol data and more about user-level data.

import requests

# Get token balances for a wallet
address = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
response = requests.get(
    f"https://deep-index.moralis.io/api/v2.2/{address}/erc20",
    headers={"X-API-Key": "YOUR_MORALIS_KEY"}
)

tokens = response.json()
for token in tokens[:5]:
    name = token.get("name", "Unknown")
    symbol = token.get("symbol", "???")
    balance_raw = int(token.get("balance", "0"))
    decimals = int(token.get("decimals", 18))
    balance = balance_raw / (10 ** decimals)
    print(f"{name} ({symbol}): {balance:.4f}")
Enter fullscreen mode Exit fullscreen mode

Best for: Building wallet-connected applications. If your app needs to show a user their DeFi positions, Moralis handles the heavy lifting.

Limitation: Protocol-level data isn't the focus. You'd still need another API for TVL and yield information.

5. 1inch API

1inch is primarily a DEX aggregator, but their developer API provides swap quotes, token data, and cross-chain information. It's the go-to if your project involves actual trading.

import requests

# Get a swap quote: 1 ETH → USDC on Ethereum
response = requests.get(
    "https://api.1inch.dev/swap/v6.0/1/quote",
    params={
        "src": "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
        "dst": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
        "amount": "1000000000000000000"
    },
    headers={"Authorization": "Bearer YOUR_1INCH_KEY"}
)

quote = response.json()
dst_amount = int(quote.get("dstAmount", "0")) / 1e6
print(f"1 ETH → {dst_amount:.2f} USDC")
print(f"Gas estimate: {quote.get('gas', 0)}")
Enter fullscreen mode Exit fullscreen mode

Best for: DEX aggregation, swap quotes, and transaction building. If your app executes trades, 1inch is essential.

Limitation: Not a data API in the traditional sense. It won't help you build a TVL dashboard or compare yields.

Comparison: Which API for Which Use Case?

Use Case Best API
TVL data only DeFiLlama
Yield/APY data DeFi Data API
Token prices CoinGecko
On-chain queries The Graph
Wallet/position data Moralis
Swap execution 1inch
All-in-one DeFi data DeFi Data API

My Recommended Stack for 2026

For most DeFi projects, I recommend a two-API approach:

  1. DeFi Data API (via RapidAPI) for DeFi-specific data: protocols, yields, chains, categories, and stats. It covers the core data layer that most applications need.

  2. CoinGecko for price feeds and market data.

Here's how they work together:

import requests

# DeFi Data API — yield and protocol data
defi_headers = {
    "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",
    "X-RapidAPI-Host": "defi-data-api"
}
defi_base = "https://defi-api-425658670453.europe-west1.run.app"

# Fetch top yields
yields = requests.get(f"{defi_base}/yields/top", headers=defi_headers).json()

# Fetch protocol details for the top yield's protocol
top_protocol_slug = yields[0].get("protocol", "").lower().replace(" ", "-")
protocol = requests.get(f"{defi_base}/protocols/{top_protocol_slug}", headers=defi_headers).json()

print(f"Highest yield: {yields[0]['symbol']} at {yields[0]['apy']}% APY")
print(f"Protocol: {protocol.get('name')} — Category: {protocol.get('category')}")
print(f"Protocol TVL: ${protocol.get('tvl', 0):,.0f}")
Enter fullscreen mode Exit fullscreen mode

This combination gives you DeFi data and market context in a clean, maintainable setup.

Final Thoughts

There's no single "best" DeFi API — there's only the best API for your specific use case. DeFiLlama remains the gold standard for TVL data, and I don't see that changing anytime soon.

But if you need more than just TVL — if you need yields, protocol metadata, chain statistics, and category data from a single, well-structured API — the DeFi data API free options on RapidAPI are worth a serious look. The DeFi Data API, in particular, covers a lot of ground with just seven endpoints.

You can find it by searching "DeFi Data API" on RapidAPI. Give it a try alongside your existing tools and see if it simplifies your data layer.

Happy building! 🚀
