**APIs profiled:** 6

Filecoin is the world's largest decentralized storage network, providing cryptographically verifiable storage backed by a global network of storage providers. Developers can query storage deals, retrieval markets, miners, blocks, and Filecoin+ verified storage operations through the Glif-hosted Lotus JSON-RPC API and the Filecoin HTTP REST API. The network also exposes protocol-level actors (Miner, Market, Datacap, Verified Registry, Storage Power) through built-in actor methods, and offers high-level storage onramps such as Filecoin Onchain Cloud (Synapse SDK) and S3-compatible Fil One storage.
