Blocks Subgraphs

Blocks subgraphs are commonly needed for applications that require block-level data such as timestamps, block numbers, and other metadata. However, indexing blocks across an entire chain can be resource-intensive and expensive.

Free blocks subgraphs

Goldsky provides free, pre-indexed blocks subgraphs for many popular networks. These are publicly available and ready to use without any setup. Please note that these are meant for exploratory use and lightweight testing with a 50/10s rate limit, not for production or scraping workloads. The endpoints may be changed or removed at any point.

Endpoint format
