**A complete, typed Python client for [Helius](https://helius.dev) — the Solana developer platform.**
<br />

## TL;DR
```bash
pip install helius-python
```

```python
# export HELIUS_API_KEY=your_key   (or put it in .env)

from helius.client import HeliusClient

with HeliusClient() as helius:
    _ctx, lamports = helius.get_balance("7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU")
    print(f"{lamports / 1_000_000_000:.4f} SOL")

    for sig in helius.get_signatures_for_address(
        "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU", limit=5
    ):
        print(sig.slot, "ERR" if sig.err else "OK ", sig.signature)
```

`HELIUS_API_KEY` is read from the environment (or `.env`), the
client is a context manager, and every return value is fully typed.

## Why this over `solana-py` / `solders`?

`solders` is for building and signing transactions. `solana-py` is a generic Solana RPC client. Use them for that.

This library is for talking to **Helius** specifically — typed `pydantic` responses, snake_case, and (eventually) the Helius-only endpoints (DAS, Enhanced Transactions, Webhooks, priority fees) the others don't cover. Plays nicely alongside `solders`: sign with `solders`, read with `helius-python`.

## Example: wallet tracker

See [`examples/wallet_tracker.py`](examples/wallet_tracker.py) for a
runnable script that takes a wallet address and prints:

- SOL balance
- All non-empty SPL token accounts (mint, balance, account)
- The last N transactions (timestamp, slot, success/error, signature)

```bash
export HELIUS_API_KEY=your_helius_api_key
python examples/wallet_tracker.py 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU --limit 20
```

It uses `get_balance`, `get_token_accounts_by_owner` (with
`encoding="jsonParsed"`), and `get_signatures_for_address` — pure
stdlib plus this library, no `solana-py` or `solders` needed.

## Coverage

The goal of this library is **support every function, method, endpoint,
and feature that Helius exposes.** If Helius ships it, this client
wraps it.

- ✅ **The full Solana JSON-RPC surface** proxied by Helius —
  `getAccountInfo`, `getBalance`, `getBlock`, `getTransaction`,
  `getProgramAccounts`, `getTokenAccountsByOwner`,
  `getSignaturesForAddress`, and every other standard RPC method.
  **(supported today)**
- 🚧 **All Helius-specific RPC extensions** — enhanced transactions, DAS
  (Digital Asset Standard) methods, priority fee estimation, and the
  rest of the Helius-only RPC namespace. **(in progress)**
- 🚧 **Every Helius REST endpoint** — Enhanced Transactions API,
  Webhooks API, Mint API, token metadata, address lookups, and beyond.
  **(in progress)**
- 🚧 **Platform features** — streaming, websockets, and any new
  capability Helius adds to its API. **(in progress)**

> **Current status:** only the standard Solana JSON-RPC surface is
> implemented today. Support for Helius RPC extensions, REST endpoints,
> and platform features is actively being worked on.

## Goals

1. **Completeness** — 1:1 coverage of the entire Helius API surface.
2. **Type safety** — fully typed responses.
3. **Pythonic ergonomics** — `get_account_info(...)` instead of
   `getAccountInfo(...)`, context managers.
4. **Zero magic** — thin, predictable wrappers that map directly to the
   documented Helius API.

## Authentication

Pass your Helius API key explicitly:

```python
from helius.client import HeliusClient

client = HeliusClient(api_key="YOUR_HELIUS_API_KEY")
```

or set `HELIUS_API_KEY` as an environment variable:

```bash
export HELIUS_API_KEY=your_helius_api_key
```

You can also set it in a `.env` file at the project root and let the
client pick it up automatically:

```env
HELIUS_API_KEY=your_helius_api_key
```

```python
from helius.client import HeliusClient

client = HeliusClient()  # reads HELIUS_API_KEY from the environment or .env
```

## Usage

### As a context manager (recommended)

```python
from helius.client import HeliusClient

with HeliusClient(api_key="YOUR_HELIUS_API_KEY") as client:
    _ctx, balance = client.get_balance("So11111111111111111111111111111111111111112")
    _ctx, supply  = client.get_supply()
    nodes         = client.get_cluster_nodes()
    block         = client.get_block(slot=250_000_000)
    tx            = client.get_transaction("5j7s...signature...")
```

`HeliusClient` implements the context-manager protocol via `__enter__` /
`__exit__`, so the underlying `httpx.Client` is closed cleanly when the
`with` block exits.

### With an explicit `close()` call

If a `with` block doesn't fit your code structure (e.g. the client lives
on a long-lived object), call `close()` yourself when you're done:

```python
from helius.client import HeliusClient

client = HeliusClient(api_key="YOUR_HELIUS_API_KEY")
try:
    _ctx, balance = client.get_balance("So11111111111111111111111111111111111111112")
    _ctx, supply  = client.get_supply()
finally:
    client.close()
```

Client classes also implement `__del__` as a safety net — if you forget
to `close()` or use `with`, the underlying HTTP client is still closed
when the instance is garbage-collected. Prefer `with` or `close()`
regardless.

> 🚧 **Exception & error handling is a work in progress.** Today,
> transport errors surface as raw `httpx` exceptions and Helius/Solana
> RPC errors are not yet wrapped in typed exception classes. A
> consistent error hierarchy is being worked on.

| `base_url` | `"https://mainnet.helius-rpc.com"`                                        | Override to point at devnet, staging, or a custom Helius endpoint. |
| `api_key`  | `None` → falls back to `HELIUS_API_KEY` from the environment, then `.env` | If none is provided, the constructor raises `ValueError`.          |

Per-method RPC parameters (`commitment`, `encoding`, `min_context_slot`,
etc.) are left unset by default — the Helius/Solana server defaults
apply unless you pass them explicitly.

### Reference

For parameters, semantics, and return shapes, see the official Helius docs:
[RPC guide](https://www.helius.dev/docs/rpc) and
[API reference](https://www.helius.dev/docs/api-reference).

If you hit a bug, a missing parameter, or surprising behavior, please
[open an issue](https://github.com/markosnarinian/helius-python/issues).

### Supported methods

The method names map 1:1 to the Solana JSON-RPC spec, just converted to
`snake_case`. If you know the RPC method name, you know the Python function.

## Status

Actively expanding toward full coverage of the Helius API. See
[`src/helius/client.py`](src/helius/client.py) for the current list of
implemented methods; missing endpoints are tracked as issues and added
continuously.
