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).

Modules on Filecoin

Toolbox (Discovery & comparison)

• What it is: a chain-specific marketplace/registry of Web3 services.

• Key features:

  • Discover: browse categories and filter offers

  • Compare: side-by-side comparison

  • AI search: search across the database (including cross-ecosystem queries)

  • Widget for docs: embed a compact Toolbox view into documentation

  • Contributing: improve the open-source database

• Open: https://filecoin.chain.love/

Performance (Monitoring & routing)

• What it is: a module to manage providers' performance.

• Key areas:

  • Monitoring

  • Notifications

  • Load balancer

  • Performance agreements

• Open: https://filecoin.chain.love/configurations

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:

curl --location 'https://filecoin.chain.love/rpc/v1' \
--header 'Content-Type: application/json' \
--data '[
    {
	    "jsonrpc":"2.0",
	    "method":"Filecoin.ChainHead",
	    "params":[],
	    "id":1
    },
    {
	    "jsonrpc":"2.0",
	    "method":"Filecoin.ChainHead",
	    "params":[],
	    "id":2
    }
]'

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:

FULLNODE_API_INFO=QUERY_KEY:ENDPOINT lotus daemon --lite

The available endpoints are:

Network	Endpoint
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>

Mainnet

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

Pricing

This section serves as the definitive guide for all Filecoin-related pricing information.

Growth Plan

The Growth plan offers a cost-effective way to access Filecoin APIs. You pay a one-time access fee and then only pay for the credits you use. The underlying infrastructure is shared between you and other users.

Endpoint	Network	Data Availability	Access Fee	Cost per 1M Credits
Recent-state mainnet	Mainnet	Latest 2k blocks	Free	$1
FVM archive mainnet	Mainnet	All blocks since FEVM launch	$300	$1.5
Full archive mainnet	Mainnet	All blocks since genesis	$500	$3
Recent-state calibnet	Calibnet	Latest 2k blocks	Free	$0.5
Full archive calibnet	Calibnet	All blocks since genesis	$100	$1.5

Notice: Recent-state mainnet and recent-state calibnet endpoints have separate HTTPS and WebSocket implementations that are shown as separate endpoints in the UI. This is purely a UI implementation detail so do not be confused: they are billed as a single endpoint.

Dedicated Nodes

The Dedicated plan provides exclusive nodes for your specific needs. You only pay a fixed monthly fee. The underlying infrastructure is dedicated to you.

Network	Data Availability	Monthly Fee
Mainnet	Latest 2K blocks	$1000
Mainnet	All blocks since FEVM launch	$3500
Mainnet	All blocks since genesis	$5000
Calibnet	Latest 2K blocks	$600
Calibnet	All blocks since genesis	$800
