glifio / filecoin-rpc-proxy

Overview

filecoin-rpc-proxy is a caching solution for the Filecoin JSON RPC API to reduce endpoint load used by the Glif Filecoin Hosted Endpoints service.

The config.yaml is a configuration reference where you can specify any methods to cache and the caching parameters, such as cache TTL, auto-update, key caching parameters and other custom parameters.

(Current methods we cache include ChainGetTipsetByHeight, ClientQueryAsk, StateCirculatingSupply, StateMarketDeals which can have large responses and/or often requested by our users.)
