trace_block on Zircuit
Returns trace_* call traces for every transaction in a block — the trace-module equivalent of debug_traceBlockByNumber. Heavy; needs a free API key.
Flat trace_* actions for a whole block. The trace_ namespace is Erigon/OpenEthereum-lineage and not every client exposes it, so confirm support on the specific chain before relying on it.

trace_block on Zircuit — FAQ
How do I call trace_block on Zircuit?
POST a JSON-RPC 2.0 request with "method": "trace_block" to NodeFlare's Zircuit endpoint at https://rpc.nodeflare.app/zircuit/v1/YOUR_KEY. This method requires a free API key — it is not available on the public endpoint.
What does trace_block cost on the free tier?
trace_block is weighted at 100 compute units per call. The free tier includes 2,000,000 CU/month, so that is roughly 20,000 trace_block calls per month — no credit card.
Is trace_block available on the public Zircuit endpoint?
No. trace_block is a heavy method and requires a free API key. The public no-key endpoint serves standard read methods; create a free key to unlock trace_block, eth_getLogs, trace_* and debug_*.
Anything Zircuit-specific to know when using trace_block?
debug_ tracing is available on our node. Traces are stable once a block is sequenced.
