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

Recommended workflows

• Need an RPC endpoint right now: open API Management → use the RPC endpoint below.

• Harden production access: open Performance → set monitoring/notifications → configure routing and failover.

• Need an RPC/Subgraphs right now: open API Management → 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: Provides public anonymous access with 100 requests per second.

• Recent-state API (Premium): Provides access to less "busy" and more stable fleet of nodes. Available on the Growth Plan.

• Archival Node: This node provides access to the entire blockchain history, starting from genesis, as is. API is fully compatible with the Ethereum JSON-RPC API. Only POST endpoints are supported.

• Dedicated nodes are also available on-demand.

Subgraphs (Indexing)

Subgraphs can be created 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>

Mainnet

# 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":{}}' \
