audit_token_approvalsread-onlyAudits the token approvals an address has granted: who may move its tokens. How: scans the chain for the owner's Approval and ApprovalForAll events (from "from_block", default the genesis block, in ranges of the server's log range limit), keeps the latest per token and spender, and checks each against the contract's current state with eth_call (allowance, isApprovedForAll, or getApproved and owner
block_rewardread-onlyWhat the miner of a block earned: the subsidy from the emission schedule (50 LAX halved every 210,000 blocks) plus the transaction fees (the sum over its transactions of gas used à effective gas price; Parallax burns nothing). Amounts in wei and LAX. Also the coinbase address, the block's height and era, and whether the reward has matured: it can be spent from 100 blocks after the block (coinbase
call_contractread-onlyRuns a read-only eth_call against a contract and decodes the result. Nothing is signed or sent: state changes are discarded. Give either raw "data" (0x-hex calldata), or "function" plus "args": - function is a name ("balanceOf") resolved against "abi" (a JSON ABI you pass) or, when abi is omitted, the contract's verified ABI from the explorer; or a full signature such as "balanceOf(address) return
chain_inforead-onlyIdentity and state of the Parallax node this server reads: chain ID (2110 on mainnet), network ID, client version, head block (number, hash, timestamp, seconds since it was mined), sync status, peer count, current gas price, and the RPC namespaces the node serves (tools needing debug, txpool, admin or xhash work only when listed). Takes no arguments. Call it first to check the server is on the exp
estimate_gasread-onlyEstimates the gas a transaction would use (eth_estimateGas) and what it would cost at the node's current gas price: fee = gas à gas price, in wei and LAX. Takes the same call fields as call_contract (to, from, value_wei, and data or function+args) and nothing is sent. A plain LAX transfer uses 21,000 gas. Fails with the revert reason when the transaction would revert.
explorer_addressread-onlyWhat the explorer knows about an address: LAX balance (wei and LAX), whether it is a contract and verified, its name and public tags, whether the explorer flags it as a scam, proxy implementations, the creator and creation transaction of a contract, token metadata if it is a token, and counters: transactions, token transfers, gas used and blocks mined. Names, symbols, tags and method names are set
explorer_chartsread-onlyTime series from the explorer's statistics service. Without "chart", lists the available charts with id, section, description, units and resolutions: accounts (accountsGrowth, activeAccounts, newAccounts), transactions (newTxns, txnsGrowth, txnsFee, averageTxnFee, txnsSuccessRate), blocks (newBlocks, averageBlockSize, averageBlockRewards), LAX transfers (newNativeCoinTransfers), gas (averageGasPri
explorer_contractread-onlyA verified contract's metadata: name, language, compiler version, EVM version, optimization, license, verification time, proxy type and implementations, and its interface: every function (signature, state mutability) and event from the verified ABI. With include_source=true, the source code is returned too (main file, cut at max_source_bytes, default 20,000, at most 100,000), with the names and si
explorer_internal_transactionsread-onlyValue transfers and calls made by contracts during transactions (internal transactions), for one transaction ("transaction": hash) or an address ("address"): type (call, create, delegatecall, selfdestructâ¦), from, to, value (wei and LAX), success and error. The node's public RPC does not trace, so this is the way to see internal LAX movements without a debug-enabled node (see trace_transaction).
explorer_searchread-onlyThe explorer's search: finds addresses, tokens (by name or symbol), contracts, transactions and blocks matching a query, such as "pepe", a hash or an address. Returns each match's type, name, symbol, address or hash and whether a contract is verified. Names, symbols, tags and method names are set by whoever deployed or verified a contract and are wrapped as untrusted.
explorer_statsread-onlyChain-wide counters from the explorer: total blocks, transactions, addresses, accounts, contracts (and verified ones), tokens and LAX transfers; transactions and fees in the last 24 hours, the average fee, and the average block time in seconds (the explorer's figure; mining_stats derives its own from block headers). Units are given per counter; fees are in LAX.
explorer_tokenread-onlyA token's metadata: name, symbol, type (ERC-20, ERC-721, ERC-1155), decimals, total supply (raw and in whole tokens) and number of holders. Names, symbols, tags and method names are set by whoever deployed or verified a contract and are wrapped as untrusted.
explorer_token_balancesread-onlyThe ERC-20, ERC-721 and ERC-1155 balances of an address (at most 100 tokens), each with the token's address, name, symbol, type, decimals, the raw balance and the balance in whole tokens (raw ÷ 10^decimals). LAX itself is not a token: use explorer_address or get_balance. Names, symbols, tags and method names are set by whoever deployed or verified a contract and are wrapped as untrusted.
explorer_token_holdersread-onlyA token's holders, largest first: address, the explorer's name for it, whether it is a contract, the balance (raw and in whole tokens) and its share of the total supply (0 to 1). Results come 50 per page, newest first; pass "next_cursor" from a result as "cursor" to get the next page. "limit" returns fewer items, but a page cut by limit has no next_cursor, so leave limit out when paging through ev
explorer_token_transfersread-onlyToken transfers of a token ("scope": "token", the default) or to and from an address ("scope": "address"): transaction hash, block, time, from, to, token, amount (raw and in whole tokens) or token ID. Results come 50 per page, newest first; pass "next_cursor" from a result as "cursor" to get the next page. "limit" returns fewer items, but a page cut by limit has no next_cursor, so leave limit out
explorer_transactionsread-onlyTransactions sent from or to an address, as the explorer indexed them: hash, block, time (UTC), from, to, value (wei and LAX), fee (wei and LAX), status, the called method's name, and transaction types (coin_transfer, contract_call, token_transfer, contract_creation). "direction" is "all" (default), "in" or "out". Results come 50 per page, newest first; pass "next_cursor" from a result as "cursor"
gas_priceread-onlyCurrent fee levels in wei and gwei (1 gwei = 10^9 wei). Parallax has no EIP-1559 base fee: a transaction pays gas used à gas price, all of it to the miner. Returns the node's eth_gasPrice and, from Parallax's Bitcoin Core-style fee estimator (eth_estimateSmartFee), the price expected to confirm within 1, 3, 6, 36 and 144 blocks (10 minutes to a day) with the estimator's historical success rate fo
get_balanceread-onlyThe LAX balance (wei and LAX) and nonce (transactions sent) of an address, at the latest block or at "block" (number or hash). Reading a block older than the node's recent state window needs an archive node; the error says so when it is not one. Note that block rewards cannot be spent until 100 blocks after the block that paid them (coinbase maturity), although they are included in the balance.
get_blockread-onlyA block by number, hash or "latest". Returns number, hash, parent hash, timestamp (Unix seconds), seconds since its parent (block time; the target is 600), miner, difficulty, gas used/limit, size in bytes, epochStartTime (a Parallax header field: the timestamp of the last block at a multiple of 2016), extraData (as untrusted text when printable), the block subsidy in wei and LAX, and its transacti
get_coderead-onlyThe deployed bytecode of an address at the latest block or "block": whether it is a contract, the code size in bytes and its keccak256 hash. With include_code=true the bytecode itself is returned as hex (cut at 4096 bytes). An address with no code is an externally owned account (or a contract that self-destructed). For source code and ABI use explorer_contract.
get_logsread-onlyEvent logs in a block range, filtered by contract address(es) and topics (eth_getLogs). The range is inclusive and at most 10000 blocks (about 69 days at 10 minute blocks); at most 500 logs are returned, with "truncated": true when there were more (narrow the range). from_block and to_block take numbers or "latest"; to_block defaults to latest and from_block to to_block â 1000. topics follow eth
get_proofread-onlyThe Merkle proof of an account and optionally some of its storage slots (eth_getProof, EIP-1186) at the latest block or "block": balance, nonce, code hash, storage root and the slot values. The proof nodes are only counted unless include_proof=true, as they are large; use them to verify state against a block's stateRoot without trusting this server or the node.
get_receiptread-onlyThe receipt of a mined transaction: status (success or failed), gas used, effective gas price (wei), fee paid (wei and LAX = gas used à gas price), the address of a created contract, and its event logs (at most 100). Each log has its address and raw topics and data, plus a decoding with the contract's verified ABI or the standard ERC-20/721 events when they match. Event string values are untruste
get_storage_atread-onlyThe raw 32-byte value of one or more storage slots of a contract (at most 20), at the latest block or "block". Slots are decimal or 0x-hex numbers, or 32-byte hex keys for mapping entries computed off-chain. Values are returned as 0x-hex and as unsigned decimal.
get_transactionread-onlyA transaction by hash: block, position, from, to, value (wei and LAX), gas limit, gas price (wei; Parallax has no base fee, so this is the whole price per gas), nonce, type (0 legacy, 1 access list; Parallax has no type 2), and its calldata. Calldata is shown as hex (first 2048 bytes) and, when possible, decoded: with the contract's verified ABI from the explorer ("source": "verified") or else the
mempool_statusread-onlyTransactions waiting to be mined. From the configured node (txpool namespace): "pending" (executable now) and "queued" (waiting for an earlier nonce) counts. From the status page: the median pending count across synced reporting nodes, "pressure" (the block space the waiting transactions need, as a share of one block: under 0.5 is light, over 2 is a backlog) and blocks to clear; plus the node's cu
mining_statsread-onlyMining figures derived from the headers of the last "blocks" blocks (default 144, about a day; at most 2016), with how each is worked out: - seconds_since_last_block: now â the head block's timestamp. Blocks arrive as a Poisson process, so the time already waited says nothing about the wait to come. - block_time: statistics of the intervals between consecutive timestamps in the window (mean, med
network_healthread-onlyOne-call health report of the Parallax network, combining the status page (status.parallaxprotocol.org) with the configured node. From the status page: the best block and seconds since it was found, reporting nodes (total, active, synced), active alerts with level (critical, warn, info) and details (types: split = verified nodes on different chains; reorg = a reorganization 3+ blocks deep; majorit
network_incidentsread-onlyThe status page's incident record: periods when an alert condition held (majority; withholding = the largest miner publishing far fewer blocks than its share predicts; spread = slow propagation; split; reorg), each with level, start and end (UTC; "ongoing" when it has not ended), duration in seconds and a description (untrusted). Covers the last "days" days (default 30, at most 90), newest first,
network_nodesread-onlyThe nodes reporting to the status page: name (operator-chosen for verified nodes, a pseudonym such as node-3f9a2c1b otherwise; untrusted), verified, client version, online/offline (and since when), syncing, mining and hashrate, peers, peer latency (ms), best block, propagation delay of the last block (left out when it was not timed: a block the node caught up to after connecting or while syncing)
network_propagationread-onlyHow fast blocks spread and how stable the chain tip is, from the status page: propagation reports with median, p90 and p99 delay (ms) after the first node saw a block, the median time for recent blocks to reach 90% of verified nodes and any consistently slow miner, delays by band; stale blocks in the last 2,000 heights, reorganization count and the last and last deep (3+ blocks) reorg with height,
network_trendsread-onlyThe status page's figures over the last 7 days in 4-hour slices (UTC, oldest first; null where nothing was measured): block_time_seconds and hashes_per_second (each pooled over the 24 hours to the slice's end, so luck in one slice does not swing them), difficulty (mean of the slice's blocks), hashprice_lax (LAX a hash per second earns per day) and security_budget_lax (LAX miners earn per day) at t
read_docread-onlyReturns a page of the Parallax documentation or a PIP in full, as Markdown: by "path" from search_docs (such as "guides/mining/pool" or "pip-0004"; "PIP-4", a parallax://docs URI or a docs.parallaxprotocol.org URL also work). Long pages come in parts of "max_bytes" (default 24,000): pass "next_offset" back as "offset" for the rest. Includes the page's published url, to cite.
search_docsread-onlySearches the official Parallax documentation (docs.parallaxprotocol.org: running a node, mining, wallets, JSON-RPC, the PVM, networking, Tor, protocol concepts) and the Parallax Improvement Proposals (PIP-0002 ASERT difficulty, PIP-0003 DNS discovery, PIP-0004 fee estimation, PIP-0005 UPnP, PIP-0006 TCP discovery). Use it whenever a question is about how Parallax works or how to do something with
supply_inforead-onlyLAX issuance against the 21,000,000 cap. Parallax follows Bitcoin's schedule: 50 LAX per block from block 1 (genesis pays nothing), halving every 210,000 blocks; there is no premine, burn or protocol lock, so circulating supply equals total issued (block rewards count from the block that pays them, although they are spendable only 100 blocks later). Returns the head height, issued supply in wei an
wait_for_new_blockread-onlyWaits until the chain has a block above "after_block" (default: the current head) and returns it: number, hash, parent hash, timestamp, miner, difficulty, gas used, transaction count and subsidy, with a reorg marker if the tip was replaced instead. Blocks come every 10 minutes on average, but intervals vary widely, so a wait can time out: then it returns "new_block": false with the current head, a
