Bitcoin: blocks and transactions

Bitcoin family endpoints expose classic bitcoind JSON-RPC names. Many forks in our catalog (Litecoin, Dogecoin, …) follow the same shapes — swap the network slug.

Steps

  1. Create a bitcoin (or fork) endpoint.
  2. Read tip: getblockcount or getbestblockhash.
  3. getblock <hash> 1 for JSON with txids; use 2 only when you need full transactions.
  4. getrawtransaction <txid> true for decoded JSON.

Tips

  • Replace placeholder hashes/txids with real mainnet values.
  • Pruned full nodes may reject historical getblock / getrawtransaction — see full-node errors.
  • Wallet RPCs that spend funds are out of scope for a shared RPC gateway.
