Advanced Use Cases with RPC

For more complex operations, leverage the RPC endpoints for raw blockchain interaction. These endpoints are ideal for advanced developers needing low-level access to blockchain data or performing operations unavailable in REST endpoints.

Example: Fetch Raw Block Data​

Retrieve raw data for a specific block. This includes detailed metadata like block hashes, timestamps, and transaction IDs.

curl -X GET "https://<chain>-rpc.numia.xyz/block?height=<block_height>" \
  -H "Authorization: Bearer <your_api_key>"

Example: Broadcast a Transaction​

Submit a new transaction to the blockchain. This requires constructing the transaction payload and encoding it in the appropriate format.

curl -X POST "https://<chain>-rpc.numia.xyz/broadcast_tx_async" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <your_api_key>" \
  -d '{ "tx": { ... } }'
