Chain.Love on Fuse currently provides the **API Management** module for RPC access.

## Recommended workflows

* **Need an RPC endpoint right now**: open [API Management](https://fuse.chain.love/rpc) → use the RPC endpoint below.
* **Harden production access**: open [Performance](https://fuse.chain.love/configurations) → set monitoring/notifications → configure routing and failover.
* **Need an RPC/Subgraphs right now**: open [API Management](https://fuse.chain.love/rpc) → use RPC/Subgraphs endpoints (details below).

### API Management (RPC & Subgraphs)

#### Sending requests

We host following JSON-RPC API endpoints for Fuse Mainnet:

* [Recent-state API](https://api.node.fuse.io/): Provides public anonymous access with 100 requests per second.
* [Recent-state API (Premium)](https://api.node.fuse.io/): Provides access to less "busy" and more stable fleet of nodes. Available on the Growth Plan.
* [Archival Node](https://fuse.chain.love/archive): This node provides access to the entire blockchain history, starting from genesis, as is. API is fully compatible with the [Ethereum JSON-RPC API](https://ethereum.org/en/developers/docs/apis/json-rpc/). Only **POST** endpoints are supported.
* Dedicated nodes are also available on-demand.

#### Subgraphs (Indexing)

Subgraphs can be [created](https://fuse.chain.love/graph) for $70/month on Fuse. You can query your subgraphs using the following methods:

* By **name**: `https://proxy.fuse.chain.love/subgraphs/name/<SUBGRAPH_NAME>`

{% tab title="Mainnet" %}

```bash
# Assuming the subgraph name is `polygon/hello`
curl -X POST \
 -H "Content-Type: application/json" \
 -d '{"query":"query MyQuery {\r\n  jobs(first: 10) {\r\n    id\r\n  }\r\n}","variables":{}}' \
 "https://proxy.fuse.chain.love/subgraphs/name/fuse/erc4337better"
