debug_getRawHeader

Last updated:

debug_getRawHeader returns the consensus-layer RLP encoding of a single block header as a 0x-prefixed hex string. This is the exact byte sequence that is hashed to produce the block hash, so it is the canonical input for verifying a header or re-deriving its hash off-chain.

Use it when you need the raw header bytes rather than the decoded JSON object that eth_getBlockByNumber / eth_getBlockByHash return — for example to feed a light-client verifier, to recompute and check a block hash, or to relay a header to another system that expects RLP.

This is a pro-tier method in the eth_debug category. It is rate-limited to 5 requests per second on the pro tier and 15 requests per second on the business tier, with burst.
