Describe the task
Ask your agent for something this skill covers. It loads helius-api automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.

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

export HELIUS_API_KEY="your-api-key"

2. Install Dependencies

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

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

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

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
`getAssetProof`	Merkle proof (compressed NFTs)	10
`getAssetProofBatch`	Batch proofs	10
`getSignaturesForAsset`	Tx history for an asset	10
`getNftEditions`	All editions of a master	10
`getTokenAccounts`	Token accounts by mint/owner	10

See references/das_api.md for complete field documentation.

Enhanced Transactions API

Transforms raw Solana transactions into human-readable structured data with categorized types and sources.

Parse a Transaction

API_URL = f"https://api-mainnet.helius-rpc.com/v0/transactions?api-key={API_KEY}"

resp = httpx.post(API_URL, json={
    "transactions": ["SIGNATURE_HERE"],
})
parsed = resp.json()[0]
# parsed["type"]        → "SWAP"
# parsed["source"]      → "JUPITER"
# parsed["description"] → "User swapped 1 SOL for 150 USDC on Jupiter"
# parsed["tokenTransfers"] → [{mint, amount, from, to}, ...]
# parsed["nativeTransfers"] → [{from, to, amount}, ...]

Get Parsed Transaction History for a Wallet

url = f"https://api-mainnet.helius-rpc.com/v0/addresses/{wallet}/transactions"
resp = httpx.get(url, params={
    "api-key": API_KEY,
    "limit": 50,
    "type": "SWAP",  # optional filter
})
history = resp.json()

Transaction Types (151+)

Key types for trading analysis:

Type	Meaning
`SWAP`	DEX swap
`TRANSFER`	Token/SOL transfer
`ADD_LIQUIDITY` / `REMOVE_LIQUIDITY`	LP operations
`NFT_SALE` / `NFT_MINT` / `NFT_LISTING`	NFT marketplace
`STAKE_SOL` / `UNSTAKE_SOL`	Staking
`CREATE_ORDER` / `FILL_ORDER`	Limit orders

Transaction Sources (50+)

JUPITER, RAYDIUM, ORCA, MAGIC_EDEN, TENSOR, MARINADE, METEORA, PHANTOM, etc.

See references/enhanced_transactions.md for full type/source enums.

Webhooks

Real-time notifications for on-chain events — no polling required.

Create a Webhook

url = f"https://api-mainnet.helius-rpc.com/v0/webhooks?api-key={API_KEY}"
resp = httpx.post(url, json={
    "webhookURL": "https://your-server.com/helius-hook",
    "transactionTypes": ["SWAP", "TRANSFER"],
    "accountAddresses": ["WalletAddress1", "WalletAddress2"],
    "webhookType": "enhanced",
    "authHeader": "your-secret-token",
})
webhook_id = resp.json()["webhookID"]

Webhook Types

Type	Data Format	Filtering
`enhanced`	Parsed (like Enhanced Transactions API)	By transaction type + account
`raw`	Unprocessed transaction data	By account only (lower latency)
`discord`	Formatted messages to Discord channel	By transaction type + account

Manage Webhooks

# List all
webhooks = httpx.get(f"{url}?api-key={API_KEY}").json()

# Update
httpx.put(f"{url}/{webhook_id}?api-key={API_KEY}", json={
    "webhookURL": "https://new-url.com/hook",
    "transactionTypes": ["SWAP"],
    "accountAddresses": ["NewWallet..."],
    "webhookType": "enhanced",
})

# Delete
httpx.delete(f"{url}/{webhook_id}?api-key={API_KEY}")

Up to 100,000 addresses per webhook (via API). 1 credit per event delivered.

Priority Fee API

Estimate optimal priority fees for transaction landing.

resp = httpx.post(RPC_URL, json={
    "jsonrpc": "2.0", "id": 1,
    "method": "getPriorityFeeEstimate",
    "params": [{
        "accountKeys": ["JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QNyVTaV4"],
        "options": {
            "includeAllPriorityFeeLevels": True,
            "recommended": True,
        }
    }]
})
fees = resp.json()["result"]
# fees["priorityFeeEstimate"]  → recommended fee (microlamports/CU)
# fees["priorityFeeLevels"]    → {min, low, medium, high, veryHigh, unsafeMax}

Level	Percentile	Use Case
`min`	0-20th	Non-urgent
`low`	20-40th	Standard transfers
`medium`	40-60th	DEX swaps (recommended default)
`high`	60-80th	Time-sensitive
`veryHigh`	80-95th	Critical timing
`unsafeMax`	100th	Emergency only

Fee in microlamports/CU. Total priority fee = microlamports/CU × compute units consumed.

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
