Simple pricing

One request counts as one Request

No compute units and no method multipliers. A trace_block costs the same as an eth_blockNumber.

  • A batch of N calls counts N.
  • Over WebSocket, each request and each subscription message counts 1.
  • Never counted: rate-limited (429) and failed (5xx) calls, rejected keys, unknown methods, and the public trial URL.

Why BlockReq

Archive & proofs

eth_call, eth_getBalance, eth_getStorageAt and eth_getProof at any historical block on Ethereum, BNB Smart Chain, Polygon, Base, Arbitrum.

Debug & trace

debug_traceTransaction, debug_traceCall, trace_block and trace_filter on the same chains with a paid plan, plus eth_call with stateOverride for simulation.

Same shape on every chain

One hostname per network, JSON-RPC over HTTPS and WebSocket, and a public trial URL to try calls without a key.

Built for AI coding assistants

A public MCP server, an Agent Skill, llms.txt and OpenRPC documents help assistants pick the right host and method.
