Open Toolbox Open Performance Open API Management (RPC & Subgraphs)
Chain.Love on Filecoin is a set of modules that help you discover providers, monitor them, and (optionally) access RPC/Subgraphs through an API gateway.
Recommended workflows
Discover providers (start here): open the Toolbox → browse categories (RPC, Indexing, Wallets, etc.) → shortlist and compare offers.
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)
This module is for accessing APIs (RPC/Subgraphs). If you’re evaluating providers or comparing options, start with the Toolbox section above.
RPC API highlights
This section highlights features and important details about the Filecoin RPC API.
API versions
Lotus offers 3 API versions: /rpc/v0 includes only native methods (Filecoin.*), /rpc/v1 supports EVM-compatible methods (eth_*), and /rpc/v2 supports F3-aware methods. If you don't specify a version (making a request to https://filecoin.chain.love), the default version used is /rpc/v1.
Notice: Parameter differences exist for native methods between these versions.
Batch requests
Chain.Love RPC supports HTTP batch requests to the Filecoin RPC API, and the service currently allows up to 100 requests in a single batch.
Example:
Lotus Lite
Chain.Love RPC offers endpoints compatible with Lotus Lite nodes. For more details, visit Lotus Lite. Start your Lotus Lite node by substituting the query key and endpoint in the command below:
The available endpoints are:
Mainnet
wss://filecoin.chain.love/ws
Calibnet
wss://calibration.filecoin.chain.love/ws
Subgraphs (Indexing)
You can query your subgraphs using the following methods:
By name:
https://proxy.filecoin.chain.love/subgraphs/name/<SUBGRAPH_NAME>
