# DefiLlama API

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

Comprehensive DeFi data from DefiLlama's API ecosystem.

## Base URLs

```

### Yields (Pro)
```bash
GET /yields/pools           # All yield pools
GET /yields/chart/{pool}    # Pool history
GET /yields/poolsBorrow     # Borrow rates

```

### Volume
```bash
GET /api/overview/dexs              # DEX volumes

;; Prices
(dl/price "ethereum:0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48")
(dl/price-chart "coingecko:ethereum" {:period "30d"})

;; Yields
(dl/yield-pools)
(dl/pool-chart "747c1d2a-c668-4682-b9f9-296708a3dd90")

;; Volumes

```

## 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

## SDF Interleaving

This skill connects to **Software Design for Flexibility** (Hanson & Sussman, 2021):

### Primary Chapter: 10. Adventure Game Example

**Concepts**: autonomous agent, game, synthesis

### GF(3) Balanced Triad

```
defillama-api (○) + SDF.Ch10 (+) + [balancer] (−) = 0
```

**Skill Trit**: 0 (ERGODIC - coordination)

### Secondary Chapters

- Ch1: Flexibility through Abstraction
- Ch4: Pattern Matching

### Connection Pattern

Adventure games synthesize techniques. This skill integrates multiple patterns.
