DefiLlama API

Trit: -1 (MINUS - Validator/Data Source) Color: #4A90D9 (Cold blue, 210°)

Comprehensive DeFi data from DefiLlama's API ecosystem.

Matching Keywords (intent triggers)

Use this skill when users ask about any of the following:

TVL: TVL ranking, protocol TVL, chain TVL, TVL changes, DeFi market share
Stablecoin yield: stablecoin yield, USDC/USDT APY, low-risk yield pools, safe yield, fixed-income-like DeFi
Yield / Farming: APY ranking, yield pool screening, vault yield, lending APY, borrow rates, LSD/LRT yield
DEX / Fees / Revenue: DEX volume, protocol fees, protocol revenue, revenue growth, which DEX revenue is growing fastest
Flows / Rotation: capital flows, chain inflow/outflow, stablecoin netflow, liquidity rotation
Protocol Research: protocol fundamentals, multi-protocol comparison, sector comparison, DeFi snapshot/report

Typical user prompts this skill should match:

“Which DEX has seen the strongest revenue growth recently?”
“Find me some low-risk stablecoin yield options with decent returns.”
“Create a DeFi market snapshot for today (TVL / volume / fees).”
“Compare ETH vs SOL on-chain flow changes over the last 30 days.”

Base URLs

API	Base URL	Auth
Free API	`https://api.llama.fi`	None (no key needed)
Pro API	`https://pro-api.llama.fi/{API_KEY}`	Key in path `/API_KEY/endpoint`
Bridge API	`https://bridges.llama.fi`	None

Key rule: Use
https://api.llama.fi
for all free endpoints (TVL, chains, DEX, fees, prices). Use
https://pro-api.llama.fi/{API_KEY}
ONLY for pro endpoints (yields, derivatives, emissions). Env var:
DEFILLAMA_API_KEY
— used in pro URL path, NOT as HTTP header.

Most Common Endpoints (Start Here)

For 90% of DeFi analytics tasks, use these free endpoints (

api.llama.fi

Task	Endpoint	Example
TVL Top N protocols	`GET /protocols`	Sort by `.tvl` field
Single protocol detail	`GET /protocol/{slug}`	e.g. `/protocol/aave`
Chain TVL history	`GET /v2/historicalChainTvl/{chain}`	`.date` + `.tvl` fields
DEX volumes	`GET /overview/dexs?excludeChart=true`	`.total24h` , `.total7d`
Protocol fees	`GET /overview/fees?excludeChart=true`	`.total24h`
All chains TVL	`GET /v2/chains`	Sum `.tvl` for global total

⚠️ Pro endpoints (
/yields/*
,
/emissions
, etc.) require
DEFILLAMA_API_KEY
in the URL path.

Proxy Requirement (sc-proxy)

When using fake API keys (for example

fake-defillama-key-12345

), requests must go through sc-proxy so the key can be replaced upstream.

Env key name:
```
DEFILLAMA_API_KEY
```
Auto proxy detection envs:
```
PROXY_HOST
```
,
```
PROXY_PORT
```
If
```
HTTP_PROXY
```
/
```
HTTPS_PROXY
```
are unset, direct requests may hit upstream and return key errors.

Python template (recommended)

python

import os
import requests

host = os.getenv("PROXY_HOST")
port = os.getenv("PROXY_PORT")
session = requests.Session()
if host and port:
    if ":" in host and not host.startswith("["):
        host = f"[{host}]"  # IPv6-safe
    proxy = f"http://{host}:{port}"
    session.proxies.update({"http": proxy, "https": proxy})

# Free endpoint (no key needed):
r_free = session.get("https://api.llama.fi/protocols", timeout=25)
print("Free:", r_free.status_code)

# Pro endpoint (key in URL path):
api_key = os.environ["DEFILLAMA_API_KEY"]
r_pro = session.get(f"https://pro-api.llama.fi/{api_key}/yields/pools", timeout=25)
print("Pro:", r_pro.status_code)

GF(3) Integration

This skill serves as MINUS (-1) validator in triads:

Provides authoritative DeFi data
Validates protocol metrics
Constrains analysis with real data

Compose with:

```
aptos-agent
```
(+1): Execute based on data
```
exa-search
```
(0): Enrich with web context

Output Format Guidelines (Chinese/English Queries)

Always format DeFi data responses as human-readable markdown. Support both Chinese and English queries.

Number Formatting

TVL ≥ $1B →
```
$X.XXB
```
; TVL ≥ $1M →
```
$XXXM
```
APY →
```
XX.X%
```
24h changes →
```
+X.X%
```
or
```
-X.X%
```
Always include units:
```
$
```
,
```
%
```
,
```
B
```
(billion),
```
M
```
(million)

Recommended Output Templates

TVL Leaderboard:

markdown

| # | Protocol | TVL | Chains |
|---|--------------|-----|-----------|
| 1 | Aave V3      | $24.7B | Ethereum, Arbitrum |

Yield Pools:

markdown

| Pool | APY | TVL | Risk |
|---------|-----|-----|---------|
| USDC    | 5.2% | $500M | ✅ Low risk |

Market Snapshot:

markdown

| Metric | Value |
|------------|-----------|
| Total TVL       | $96B       |
| DEX 24h volume  | $5.7B      |
| Fees 24h        | $49M       |

Risk Labels

Always include risk indicators for yield pools:

```
✅ Low risk
```
— stable APY < 20%, no IL risk
```
⚠️ Medium risk
```
— APY 20-100%, or IL risk present
```
🔴 High risk
```
— APY > 100% (likely incentive-driven, unsustainable)

Tip: excludeChart Parameter

For volume/fee overview endpoints, always add

?excludeChart=true

to reduce response size:

bash

GET /overview/dexs?excludeChart=true    # DEX volumes (much faster)
GET /overview/fees?excludeChart=true    # Fee data (much faster)

Common Pitfalls & Gotchas

1. Wrong Base URL for Free Endpoints

❌ WRONG:

https://pro-api.llama.fi/protocols

→ returns 404 "Path needs to start with /yields/..." ✅ CORRECT:

https://api.llama.fi/protocols

Free endpoints NEVER go through

pro-api.llama.fi

2. Pro Endpoint Without API Key

❌ WRONG:

https://pro-api.llama.fi/yields/pools

→ 401 or wrong route ✅ CORRECT:

https://pro-api.llama.fi/{DEFILLAMA_API_KEY}/yields/pools

The API key is in the URL path, not in a header.

3. Missing

excludeChart=true

for Volume/Fee Endpoints

Without this param,

/overview/dexs

returns large chart history arrays. Always add

?excludeChart=true

for summary queries.

4. Handling TVL Null Values

When sorting protocols by TVL, filter first:

python

valid = [p for p in protocols if isinstance(p.get('tvl'), (int, float)) and p['tvl'] > 0]

5. Stablecoins vs TVL

DefiLlama's chain TVL includes ALL DeFi assets, not just stablecoins. For stablecoin-specific flows, use the

stablecoins.llama.fi

API (separate from pro-api). When asked about "stablecoin flows", the chain TVL change is a reasonable proxy.

6. Yields Pool UUID

The

pool

field in

/yields/pools

is a UUID like

"747c1d2a-c668-4682-b9f9-296708a3dd90"

. Use this UUID (not token address) for

/yields/chart/{pool}

history.

7. Stablecoin Yield Screening Baseline

For “conservative stablecoin yield” requests, start with this baseline filter:

```
stablecoin == true
```
```
tvlUsd >= 50_000_000
```
```
apy
```
between
```
2
```
and
```
20
```
(drop extreme incentive spikes)
```
ilRisk == "no"
```
Prefer
```
exposure == "single"
```
for conservative profiles

Workflow Examples (Agent Recipes)

Recipe 1: DeFi TVL Top 10 (1 call)

python

r = requests.get("https://api.llama.fi/protocols")
protocols = r.json()
top10 = sorted([p for p in protocols if p.get('tvl',0) > 0], key=lambda x: x['tvl'], reverse=True)[:10]
# Output: markdown table with | # | Protocol | TVL | Chain |

Recipe 2: ETH vs SOL 30-day TVL comparison (2 calls)

python

r1 = requests.get("https://api.llama.fi/v2/historicalChainTvl/Ethereum")
r2 = requests.get("https://api.llama.fi/v2/historicalChainTvl/Solana")
# Filter last 30d: [d for d in r1.json() if d['date'] >= time.time() - 30*86400]
# Output: | Chain | TVL 30d ago | TVL today | Change % |

Recipe 3: Stablecoin yield shortlist (1 call)

python

r = requests.get(f"https://pro-api.llama.fi/{API_KEY}/yields/pools")
raw = r.json()
pools = raw.get('data', raw) if isinstance(raw, dict) else raw
safe = [p for p in pools
        if p.get('stablecoin') is True
        and (p.get('tvlUsd') or 0) >= 50_000_000
        and (p.get('apy') or 0) >= 2
        and (p.get('apy') or 0) <= 20
        and p.get('ilRisk') == 'no']
top = sorted(safe, key=lambda x: x.get('apy', 0), reverse=True)[:10]
# Output: | Project | Chain | Symbol | APY | TVL | Risk |

Recipe 4: DeFi Market Snapshot (3 calls)

python

chains = requests.get("https://api.llama.fi/v2/chains").json()
dexs   = requests.get("https://api.llama.fi/overview/dexs?excludeChart=true").json()
fees   = requests.get("https://api.llama.fi/overview/fees?excludeChart=true").json()
# total_tvl = sum(c['tvl'] for c in chains if isinstance(c.get('tvl'), (int,float)))
# Output: snapshot table with TVL, DEX 24h vol, Fee 24h

Recipe 5: Protocol TVL spike analysis (2 calls)

python

r1 = requests.get("https://api.llama.fi/protocols")  # find protocol with big change_1d
r2 = requests.get(f"https://api.llama.fi/protocol/{slug}")  # get chainTvls detail
# Output: | Hypothesis | Explanation | How to verify | (table + step-by-step verification)

Stablecoin Data

For stablecoin-specific analytics (distinct from general TVL), use the stablecoins API:

bash

# Stablecoins overview (separate from pro-api)
GET https://stablecoins.llama.fi/stablecoins?includePrices=true

# Chain-specific stablecoin data
GET https://stablecoins.llama.fi/stablecoincharts/{chain}
# chain = "Ethereum", "Solana", "BSC", etc.

# All chains stablecoin summary
GET https://stablecoins.llama.fi/stablecoinchains

When users ask about "stablecoin net flows" or "stablecoin inflows":

Use
```
stablecoincharts/{chain}
```
for 30-day stablecoin TVL change (more accurate than general TVL)
Or use
```
/v2/historicalChainTvl/{chain}
```
as proxy if stablecoin API is unavailable

Yields Pool Data Handling

The

/yields/pools

response is

{"data": [...], "status": "success"}

python

r = session.get(f"https://pro-api.llama.fi/{api_key}/yields/pools")
raw = r.json()
pools = raw.get('data', raw) if isinstance(raw, dict) else raw
# Filter example: TVL > $50M and APY > 0
filtered = [p for p in pools if p.get('tvlUsd', 0) >= 50_000_000 and (p.get('apy') or 0) > 0]

Key pool fields:

Field	Type	Description
`pool`	UUID string	Unique pool identifier
`chain`	string	Chain name
`project`	string	Protocol name
`symbol`	string	Token pair (e.g. "USDC-WETH")
`tvlUsd`	number	TVL in USD
`apy`	number	Current APY %
`apyBase`	number	Base APY (lending/trading fees)
`apyReward`	number	Incentive APY (token rewards)
`ilRisk`	"yes"/"no"	Impermanent loss risk
`exposure`	"single"/"multi"	Single vs multi-asset exposure
`apyPct7D`	number	APY change past 7 days
