Blockchain JSON-RPC on 23 EVM chains for AI agents - free tier, API key, or x402 pay-per-call.
Blockchain JSON-RPC on 23 EVM chains for AI agents - free tier, API key, or x402 pay-per-call.
Blockchain JSON-RPC for AI agents on 23 EVM chains — Ethereum, Base, BNB Chain, Arbitrum, Optimism, Avalanche, HyperEVM, Polygon, and young chains like Robinhood Chain, Plasma, Ink, Zircuit, BOB and Soneium. Served from NodeFlare's own bare-metal nodes across 5 regions.

| Tool | What it does |
|---|---|
| list_chains | The 23 supported chains with chain IDs and endpoints |
| get_block_number | Latest block number (decimal + hex) |
| get_balance | Native-token balance — raw wei + human-readable amount in the chain's currency |
| get_transaction_receipt | Transaction receipt by hash |
| eth_call | Read-only contract call |
| get_logs | Contract event logs (heavy — key or x402 wallet) |
| rpc_call | Any JSON-RPC method on any supported chain |
| get_transaction | Transaction by hash (from, to, value, input) |
| get_block | Block by number/tag, optional full transactions |
| get_gas_price | Current gas price + EIP-1559 priority fee |
| get_token_balance | ERC-20 balance, raw + human-readable |
| get_token_metadata | ERC-20 name, symbol, decimals, total supply |
| resolve_ens | ENS name → address (forward) or address → primary ENS name (reverse) |
| get_token_price | Current USD price of an ERC-20 (DefiLlama, keyless) — price, symbol, confidence |
| compare_gas | Gas price across chains in one call, cheapest first, so an agent picks where to transact |
| get_multichain_balances | Native + ERC-20 balances for one address across many of the 23 chains in one call (incl. young chains); pay-per-call with an x402 wallet |
| get_token_allowances | ERC-20 approvals a wallet has granted across chains, with revoked ones dropped and unlimited approvals flagged (heavy — key or x402) |
| get_wallet_report | Full "know this wallet" report: balances + USD total + top holdings + active approvals, across chains (approvals half is heavy) |
| check_token_safety | Risk-check an ERC-20 before trading: ownership, proxy detection, holder concentration, honeypot simulation → risk score (deep checks heavy) |
| simulate_transaction | Tx pre-flight: will it revert, gas used, and which tokens/ETH move (asset-change tracing is heavy) |
| onchain_answer | Onchain Answer Engine — plain-English question about a wallet/token → a cited verdict in one call (key or x402; no free tier) |
