Blockchain — entry 006 of 11
Helium
Helium's original Layer-1 blockchain was retired in an April 2023 migration to Solana, and the network's chain data now ships only as bulk Postgres/CSV snapshots over torrent or a requestor-pays S3 bucket rather than a queryable API. The one remaining live HTTP endpoint is the free Entity API, which returns a Hotspot's owner, asserted (H3-obfuscated) location, and on-chain asset IDs by wallet public key. It carries no uptime guarantee and is meant for light lookups, not production traffic.
