JSON-RPC Method Reference
One page per capability: what each method does, an example request you can copy, and which chains actually serve it — measured, not claimed. Every cell below comes from the same weekly probe run that powers the method support matrix: real requests sent through the customer path (auth, routing, failover) against every EVM chain we serve.
Last probed 2026-09-13 · 54 EVM chains · ✓ served · ± some upstreams · ✗ unavailable
| Method | What it does | Chains serving it |
|---|---|---|
| eth_getBlockReceipts | All receipts for a block in one call — the indexer's shortcut. | 50/54 |
| eth_feeHistory | EIP-1559 base fees and priority-fee percentiles for fee estimation. | 51/54 |
| eth_getProof | EIP-1186 account/storage Merkle proofs, verifiable against the state root. | 46/54 |
| eth_createAccessList | EIP-2930 access-list generation via a dry-run of a transaction. | 43/54 |
| debug_traceCall | Full execution trace (opcodes, gas) for a call that is never mined. | 46/54 |
| trace_block | Parity-style internal-call traces for every transaction in a block. | 34/54 |
| txpool_status | Pending/queued counts from the node's mempool. | 33/54 |
| trace_filter | Range-scan of Parity traces — the workhorse of Safe-style indexers. | 9/54 |
| trace_transaction | Full internal-call tree for a single transaction. | 10/54 |
| batch | JSON-RPC batching — an array of calls in one HTTP request. | 53/54 |
| archive | Historical state queries pinned to old blocks via archive routing. | 45/54 (+2 partial) |
Non-EVM chains (Solana, Cosmos family, Bitcoin family, and others) speak different RPC dialects — see their individual chain pages.
