## What it does

This skill provides code patterns for interacting with Solana through Helius RPC and REST endpoints. It includes ready-to-use snippets for the Digital Asset Standard (DAS) API to look up fungible tokens, standard NFTs, and compressed NFTs by wallet or collection.

It also details the Enhanced Transactions API and Priority Fee API. These endpoints translate raw on-chain signatures into parsed swap or transfer events from protocols like Jupiter and Raydium. You also get request templates for webhook automation tracking up to 100,000 addresses per hook.

Calls require an active `HELIUS_API_KEY` along with the `httpx` and `python-dotenv` Python packages. Without the environment key, RPC and REST endpoints reject outgoing requests.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill helius-api -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/helius-api/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/helius-api/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill helius-api -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/helius-api/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill helius-api -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/helius-api/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install agiprolabs/claude-trading-skills helius-api
```

2. **Manually: put the files in place**
- File: `.github/skills/helius-api/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill helius-api -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/agiprolabs/claude-trading-skills --path skills/helius-api
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/helius-api/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill helius-api -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/agiprolabs/claude-trading-skills/tree/HEAD/skills/helius-api/SKILL.md

## When to use it
- fetch fungible token and compressed NFT balances for a wallet
- parse raw Solana transaction signatures into structured DEX swaps
- estimate optimal priority fee tiers in microlamports per compute unit
- register webhooks for real-time monitoring of wallet addresses

## Example prompts
- Query all digital assets for address `WALLET_ADDRESS` using the DAS API
- Parse the Solana transaction `SIGNATURE_HERE` and extract Jupiter swap details
- Get the recommended priority fee estimate for a transaction touching Jupiter

# Helius API — Enhanced Solana RPC

Helius extends standard Solana RPC with parsed transaction history, a unified Digital Asset Standard (DAS) API, webhooks, and priority fee estimation. Essential for wallet analysis, token metadata, and transaction monitoring.

## Quick Start

### 1. Get an API Key

Sign up at [dashboard.helius.dev](https://dashboard.helius.dev) — free tier available (1M credits/mo, no card required).

```bash
export HELIUS_API_KEY="your-api-key"
```

### 2. Install Dependencies

```bash
uv pip install httpx python-dotenv
```

### 3. Two Base URLs

Helius uses different base URLs depending on the API:

| API | Base URL | Protocol |
|-----|----------|----------|
| RPC / DAS / Priority Fees | `https://mainnet.helius-rpc.com/?api-key=KEY` | JSON-RPC 2.0 |
| Enhanced Transactions / Webhooks | `https://api-mainnet.helius-rpc.com/v0/...?api-key=KEY` | REST |

## DAS API (Digital Asset Standard)

Unified interface for querying all Solana digital assets — fungible tokens, NFTs, compressed NFTs, Token-2022.

### Get Asset Metadata

```python
import httpx, os

API_KEY = os.environ["HELIUS_API_KEY"]
RPC_URL = f"https://mainnet.helius-rpc.com/?api-key={API_KEY}"

resp = httpx.post(RPC_URL, json={
    "jsonrpc": "2.0", "id": 1,
    "method": "getAsset",
    "params": {
        "id": "So11111111111111111111111111111111111111112",  # wSOL
        "options": {"showFungible": True}
    }
})
asset = resp.json()["result"]
# asset.content.metadata.name, asset.token_info.decimals, etc.
```

### Get All Assets for a Wallet

```python
resp = httpx.post(RPC_URL, json={
    "jsonrpc": "2.0", "id": 1,
    "method": "getAssetsByOwner",
    "params": {
        "ownerAddress": "WALLET_ADDRESS",
        "page": 1,
        "limit": 100,
        "displayOptions": {
            "showFungible": True,
            "showNativeBalance": True,
            "showZeroBalance": False,
        }
    }
})
assets = resp.json()["result"]["items"]
```

### Search Assets with Filters

```python
resp = httpx.post(RPC_URL, json={
    "jsonrpc": "2.0", "id": 1,
    "method": "searchAssets",
    "params": {
        "ownerAddress": "WALLET_ADDRESS",
        "tokenType": "fungible",      # fungible | nonFungible | all
        "page": 1,
        "limit": 50,
    }
})
```

### All DAS Methods

| Method | Purpose | Credits |
|--------|---------|---------|
| `getAsset` | Single asset metadata | 10 |
| `getAssetBatch` | Up to 1,000 assets | 10 |
| `getAssetsByOwner` | All assets for a wallet | 10 |
| `getAssetsByGroup` | Assets by collection | 10 |
| `getAssetsByCreator` | Assets by creator | 10 |
| `getAssetsByAuthority` | Assets by update authority | 10 |
| `searchAssets` | Multi-criteria filtered search | 10 |
