NodeFlare

List Chains

List the EVM chains NodeFlare serves, with chain IDs and endpoint URLs.

Get Block Number

Get the latest block number on a chain (decimal and hex).

Get Balance

Get the native-token balance of an address — raw wei plus a human-readable amount in the chain's currency.

Get Gas Price

Get the current gas price on a chain (wei + gwei).

Get Transaction

Get a transaction by its hash (from, to, value, input, block, gas).

Get Transaction Receipt

Get the receipt of a transaction by hash (status, logs, gas used).

Get Block

Get a block by number or tag ('latest', 'finalized', or a hex number). Set fullTransactions to include full tx objects.

Eth Call

Execute a read-only contract call (eth_call) and return the raw result.

Get Logs

Fetch contract event logs (eth_getLogs). Heavy method — needs a free API key; blocked on the anonymous remote endpoint.

Rpc Call

Make any JSON-RPC call on any supported chain — the only way to reach the non-EVM chains. Heavy methods (eth_getLogs, trace_*, debug_*) are blocked on the anonymous remote endpoint — use a free API key for those.

Get Multichain Balances

Native + ERC-20 token balances (USD-priced) for ONE address across many of NodeFlare's 17 EVM chains in a SINGLE call — including young chains (Robinhood, Ink) that Alchemy/Moralis omit. Pass explicit token contracts per chain to read them, or set discover:true to auto-find every token the address holds (discovery uses eth_getLogs — a paid x402 method; anonymous callers get a 402 with the pay link).

Get Token Allowances

ERC-20 allowances/approvals a wallet has granted — what it has approved and for how much — across many of NodeFlare's 17 EVM chains in ONE call, including young chains (Robinhood, Ink) that revoke.cash-style tools skip. Scans Approval logs then reads the current on-chain allowance, dropping revoked ones, and flags unlimited approvals. This is a paid tool: send a NodeFlare API key (Authorization: Bearer nf_live_… header, or the apiKey argument) to get the full result; anonymous callers get a 402

Get Wallet Report

The full agent-ready 'know this wallet' report in ONE call: native + ERC-20 balances (USD-priced), a rolled-up total and top holdings, and the active token approvals (revoke risk) across many of NodeFlare's 17 EVM chains — including young chains (Robinhood, Ink) that other tools skip. Balances + USD + summary come back to anyone; the approvals scan uses eth_getLogs (a paid x402 method), so anonymous callers get the balances/portfolio with a note that approvals need x402.

Simulate Transaction

Transaction pre-flight on one chain: if you send this tx, will it revert (and why), how much gas does it take, and which tokens/ETH move? Runs eth_call + eth_estimateGas (returned to anyone) plus debug_traceCall asset-change tracing (a paid x402 method — anonymous callers get the revert/gas result with a note that asset changes need x402). Built for agents that want to check a tx before broadcasting.

Check Token Safety

Risk-check an ERC-20 token on one chain before trading it. Returns risk SIGNALS + a rule-based score: metadata (name/symbol/decimals/supply), whether the address is a contract, and ownership (renounced or the owner address) come back to anyone; the deep checks — holder concentration (top-holder share of supply) and a transfer/honeypot simulation (do transfers revert?) — are paid: send a NodeFlare API key (Authorization: Bearer nf_live_… header, or the apiKey argument) to run them; anonymous call

Onchain Answer

Ask a natural-language question about any wallet or token across NodeFlare's 17 EVM chains — incl. young chains (Zircuit, Robinhood, Ink) that big indexers omit — and get back a CITED verdict in one call. E.g. 'Is token 0x… on eth a scam?' or 'What does wallet 0x… hold?'. NodeFlare's Onchain Answer Engine plans the on-chain lookups, runs them on its own nodes, and synthesizes a sourced answer with a local LLM. Built for AI agents.

Resolve Ens

Resolve an ENS name (e.g. vitalik.eth) to its Ethereum address. Standard on-chain .eth names; returns null if the name has no resolver or address record.

Get Token Price

Current USD price of an ERC-20 token from DefiLlama (free, keyless): price + symbol + confidence, or null for unlisted/thin-market tokens. Well-covered chains only (eth, base, bnb, arb, op, avax, polygon, sonic, unichain).

Compare Gas

Compare current gas price ACROSS chains in one call - gwei per chain, cheapest first, so an agent can pick where to transact. Defaults to the majors (eth, base, arb, op, bnb, polygon); pass chains to override.
