List the 23 EVM chains NodeFlare serves, with chain IDs and endpoint URLs.
Get the latest block number on a chain (decimal and hex).
Get the native-token balance of an address — raw wei plus a human-readable amount in the chain's native currency. The address may be an ENS name (e.g. 'vitalik.eth').
Get the receipt of a transaction by hash (status, logs, gas used).
Execute a read-only contract call (eth_call) and return the raw result.
Fetch contract event logs (eth_getLogs). Heavy method: needs NODEFLARE_API_KEY or an x402 wallet (X402_PRIVATE_KEY) — costs ~$0.001 via x402.
Make any JSON-RPC call on any supported chain. Heavy methods (eth_getLogs, trace_*, debug_*) need NODEFLARE_API_KEY or an x402 wallet.
Get a transaction by its hash (from, to, value, input, block, gas).
Get a block by number or tag (e.g. 'latest', 'finalized', or a hex number). Set fullTransactions to include full tx objects instead of hashes.
Get current gas pricing on a chain: base gas price and the suggested priority fee (EIP-1559), both in wei (hex).
Get an ERC-20 token balance for an address, returned both raw and human-readable (uses the token's decimals and symbol).
Get ERC-20 token metadata: name, symbol, decimals and total supply (raw + human-readable).
