Set $SF_API_TOKEN to a key from your dashboard, then run this against Monad Mainnet.

grpcurl -H "authorization: Bearer $SF_API_TOKEN" \
  -d '{"start_block_num": -100, "final_blocks_only": true}' \
  mainnet.monad.streamingfast.io:443 \
  sf.firehose.v2.Stream/Blocks

Streams the 100 most recent blocks from Monad Mainnet. Firehose reads a negative start_block_num as an offset back from chain head, so no head lookup is needed.
