# Public RPC Endpoints

FastNode provides **free public endpoints** for selected networks. No sign-up and no API key required — point your client at the URL and start making requests right away.

| Network                                                     | Public endpoint                           |
| ----------------------------------------------------------- | ----------------------------------------- |
| [Arbitrum](/evm-networks/arbitrum.md)                       | `https://public-arb-mainnet.fastnode.io/` |
| [Binance Smart Chain](/evm-networks/binance-smart-chain.md) | `https://public-bsc-mainnet.fastnode.io/` |
| [Fantom](/evm-networks/fantom.md)                           | `https://public-ftm-mainnet.fastnode.io/` |
| [Gnosis](/evm-networks/gnosis.md)                           | `https://public-gno-mainnet.fastnode.io/` |
| [Optimism](/evm-networks/optimism.md)                       | `https://public-op-mainnet.fastnode.io/`  |
| [Tron Protocol](/other-protocols/tron-protocol.md)          | `https://public-trx-mainnet.fastnode.io/` |

All public endpoints serve **mainnet** only.

## Example

```bash
curl --location 'https://public-bsc-mainnet.fastnode.io/' \
  --header 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'
```

The EVM endpoints can also be added directly to MetaMask or any wallet as a custom RPC URL. For Tron, use the native API described on the [Tron Protocol](/other-protocols/tron-protocol.md) page.

## Fair use

{% hint style="warning" %}
Public endpoints are **shared and rate-limited**, with no SLA. Use them for testing, prototyping, and light workloads.
{% endhint %}

For production traffic, [order a node](https://fastnode.io) — you'll get a dedicated endpoint with a personal API key.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fastnode.io/node-apis/public-endpoints.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
