EVM JSON-RPC Methods

BlockReq supports standard EVM JSON-RPC over HTTPS and WebSocket. The table below is organized by common Core RPC API categories and marks methods that require archive, trace, debug, txpool, or WSS capability.

Archive support is chain-specific. Use the public chain page and dashboard chain list to confirm whether a route is archive-capable before relying on old-block state, proof, debug, or trace calls.

Request Counting is documented on Request Counting. This page describes method availability and capability only.

`debug_traceCall`	Paid / debug	Traces a call without submitting a transaction.
`trace_block`	Paid / trace	Returns traces for a block.
`trace_call`	Paid / trace	Executes and traces a call.
`trace_callMany`	Paid / trace	Executes and traces multiple calls when the chain supports it.
`trace_filter`	Paid / trace	Returns traces matching block/address filters.
`trace_get`	Paid / trace	Returns a trace by transaction hash and trace address.
`trace_rawTransaction`	Paid / trace	Traces a raw transaction.
`trace_transaction`	Paid / trace	Returns traces for a transaction.

`txpool_content`	Paid / txpool	Pending pool content when the chain supports it.

Free endpoints do not include debug_*, trace_*, or txpool_* methods. Method multipliers are documented on Request Counting.
