  title: Chainstack TON Node Get Shard Block Proof API
  version: 1.0.0
  description: Chainstack-managed RPC node API for the TON blockchain. Endpoints follow the canonical JSON-RPC over HTTPS interface for the network. Authenticate against your Chainstack node's per-node URL (e.g. https://nd-XXX-XXX-XXX.p2pify.com/). Merged from the Chainstack Developer Portal per-method fragments at https://github.com/chainstack/dev-portal/tree/main/openapi/ton_node_api.
