Create an outgoing webhook: we POST the events of its subscriptions to your HTTPS URL (port 443 or 8443, public address), signed (Standard Webhooks: webhook-id, webhook-timestamp, webhook-signature = v1,<base64 HMAC-SHA256 of "id.timestamp.body" with the secret>). Channels (WebSocket vocabulary): bridge.transfers and elysium.bridge (matched bridge legs), wallet (filter.address: up to 100 addresses, filter.channel: event kinds), hc.liquidations and hc.positions (filter.min_notional; positions >= 10000), elysium.launches, hyperevm.launches. Your URL first gets a webhook.verification POST: answer {"challenge": "<data.challenge>"} within 10 s, nothing else is sent before. The answer carries the secret once. Free tier: 2 webhooks, 5 subscriptions, 10k deliveries a day.

Delete one of your webhooks and its pending deliveries. Cannot be undone.

What an address holds, one flat list: HyperCore spot tokens (live), HyperEVM and Elysium ERC-20s and native HYPE (indexed head), each with raw units, amount, USD price and value, largest first; spam tokens left out; HyperCore perp accounts (account value, withdrawable) apart in `perp`; totals per layer and overall, each layer with its source, height and asOf. Past balances: block or at (Unix ms) on one layer (EVM: needs tokens, read on our archive node; HyperCore: the holder snapshot at or before it, 7 days kept). verify: EVM rows read again on the node at the same block (indexer drift shows as onchain.match false).

Live L2 order book of one HyperCore market from our own node: bids and asks best first as [px, sz, n] (price, size, order count), and the block it was read at. coin: perp name (BTC), spot @index (@107) or HIP-3 dex:COIN.

Bridge movements, newest first, with 24 h stats. route core_evm: HyperCore <> HyperEVM transfers, both legs matched (status, latency, how they were paired); route evm_elysium: HyperEVM <> Elysium (Orbit) deposits and withdrawals. Filter by account to follow one wallet across layers. Heavy call.

OHLCV candles of one market, ascending, UTC-aligned. hypercore: market = coin (BTC, HYPE, @107 spot, xyz:TSLA), down to 1 s. hyperevm / elysium: market = pool key from list_markets; prices in quote plus `usd` and `mcap` OHLC (USD price and market cap). Or token instead of market: a token's candles in USD through its reference pool (most liquid; the answer names it), HyperCore: its USDC market. Without from: the `limit` candles ending now. Windows over 30 days are billed as heavy calls.

One token: its links across layers, the markets it trades on (most traded first) and its 5 largest holders. hypercore: id = token name (HYPE), index or token id; hyperevm / elysium: id = 0x address. Price, FDV, liquidity and 5m–24h windows over all its pools: get_token_overview.

ERC-20 Transfer events, newest first (from, to, amount, block, tx). address: the transfers sent / received by a wallet (direction in, out or any), optionally of one token, in a window (from / to, Unix ms) or above minUsd (amount × current token price); each row with token, symbol, direction and USD value. Without address: the transfers of one token. Filtered pages may hold fewer rows than limit: keep paging with `next_cursor` (null = no more).

Open stop-loss / take-profit orders and the liquidation prices of open positions of one HyperCore market on the same price buckets: per bucket the stops by kind and side, the liquidations by side, the cascade (what fires with the move: sell = sell stop-losses + long liquidations, buy = buy stop-losses + short liquidations) and forced = cascade + take-profits (which fire against the move: sell ones above the mark, buy ones below), each with its running total from the mark outward (cumCascadeSell / cumSell downward, cumCascadeBuy / cumBuy upward); summary = cascade selling under the mark and buying over it, take-profits on the far side, and the forced totals, inside the grid. Same grid parameters as get_stop_map.

Largest holders of a token and its concentration (top-10 share…); system addresses (pools, bridges, launchpad, zero/dead) counted apart. hypercore: token = name (HYPE), kind = balances (spot) or positions (perp open interest of a coin); hyperevm / elysium: token = 0x address. Named wallets carry `entity`.

The story of one launched token: launch event, market cap, volume, holders, dev wallet and its funding, early buyers with flags, coordination signals, fees (exact from the launchpad ledger when indexed), lifecycle stage across layers and, for Ascend, progress toward the "Ascended" criteria. Elysium first, then HyperEVM LiquidLaunch.

Replayable life of a launch, oldest first: launch, swaps and transfers with the running holder count and market cap, graduation links (bridge to HyperEVM, HyperCore listing). Long histories are cut to fit (see `truncated`).

Liquidation prices of the open perp positions of one HyperCore market, bucketed by price around the mark: per bucket the longs (liquidated by a forced sell as price falls to them) and the shorts (forced buy), count, |size| and |size| × liquidation price. Real per-position prices: every account's positions at the latest snapshot (~12 min), each liquidation price from Hyperliquid's formula on the account state, not a leverage model; `coverage` gives the share of open interest that has one (portfolio-margin cross accounts have none). Same grid parameters as get_stop_map: the buckets line up.

HyperCore liquidations over a window (1h, 24h, 7d, 30d), every perp or one coin: totals (notional, count, accounts, long / short, market / backstop), per coin, per time bucket, the most liquidated accounts and the largest events.

HyperCore perp liquidations, newest first: one row per account, coin and block (side of the liquidated position, market or backstop, size, notional, average and mark price). Default window: the last 24 h; `from` older than 7 days (30 with a coin) is clamped, the answer's `from` says where it starts. Named wallets carry `entity`.

One NFT collection of an EVM layer: metadata, standards, token ids seen (counted up to 1,000), transfers / mints / burns over the 24 h before the indexed head.

Tokens of one collection by token id, ascending: current ERC-721 owner (null for ERC-1155), metadata URI. Next page: pass `next_cursor` as cursor.

Transfers (mints and burns included) of one collection or one of its tokens, newest first: from, to, token id, amount, block, tx. Next page: pass `next_cursor` as cursor.

NFTs an address holds on an EVM layer at the indexed head: ERC-721 tokens and ERC-1155 balances, counted per collection, the tokens listed up to limit.

One DEX pool of HyperEVM or Elysium: dex, factory, fee tier, hooks, tokens with USD prices, creation block / tx, price, liquidity with its USD value and how it is measured (pool balances for V2 / V3; virtual reserves of the in-range liquidity for V4 / Infinity pools: not TVL), depth to ±2 %, trades / buys / sells / USD volume / price change over 5m, 1h, 6h, 24h, and for V2-style pools the largest LP holders.

Open positions of one HyperCore perp at the latest holders snapshot: account, size, side, entry price, notional, unrealized PnL at the mark, leverage, margin mode and liquidation price when known. Sort by notional (default), upnl or liqDistance (closest to liquidation first). Named wallets carry `entity`.

USD prices in the past. With at (Unix ms): the price of up to 100 tokens at that time (last observation at or before it). With from / to / interval: USD closes per unit (1m 5m 15m 1h 4h 1d) of up to 25 tokens, gap-filled. Same sources as get_prices. Windows over 30 days are billed as heavy calls.

Current USD price of up to 100 tokens in one call, each with its source and provenance: hl_mid (HYPE / WHYPE: HyperCore spot mid; hl_oracle when no mid is recorded), hl_spot (HyperCore tokens and HyperEVM tokens linked to one: last trade of its USDC market), hl_perp, unit (USDC), pool (HyperEVM / Elysium: last swap of the token's reference pool, the most liquid one, with block / tx / logIndex). hypercore: tokens = names (HYPE, PURR) or perp coins (BTC).

State of each layer (HyperCore, HyperEVM, Elysium): indexed head block and time, lag behind the chain, live or syncing, Elysium network (testnet), HyperCore <> HyperEVM bridge matching coverage. Check it when an answer looks stale. Free.

Open trigger orders (stop-loss and take-profit) of one HyperCore market bucketed by trigger price around the mark (default ±10 %, 20 round-width buckets): per bucket the count, size and notional (size × trigger price) of stops and take-profits, sell (closes longs) and buy (closes shorts), market and limit. Position TP/SL that close the whole position (size 0) are counted apart under `whole`, sized from the latest positions snapshot when it has the position. `totals` cover every open trigger order of the coin, `below` / `above` those outside the grid. Cut at `height` (block) / `asOf`.

The balance of one token for one address: HyperCore coin name (USDC, HYPE…), or a HyperEVM / Elysium token address (`native` = HYPE; layer hyperevm unless elysium is given). 0 when not held. block / at for a past balance, verify to compare with the node.

One token from launch to perp across Elysium, HyperEVM and HyperCore: its address on each layer, the stages reached (Elysium launch, listing desk, HyperEVM mirror, HyperCore spot, perps) with chain evidence, and the links between them, each exact or inferred. address: an Elysium / HyperEVM address, core:<index>, a HyperCore token id or name, or a perp coin (dex:COIN).

One token across all its pools on HyperEVM or Elysium (DexScreener style): USD price and source, FDV, market cap, liquidity, volume / trades / buys / sells / price change over 5m, 1h, 6h, 24h, holders and top-10 share, pool count, the 5 best pools and the reference one, creator and creation time.

Is this HyperEVM or Elysium ERC-20 safe to trade: a buy, a transfer and a sell simulated on our node through its most liquid pool (state overrides, nothing sent): canBuy, canSell, buy / sell / transfer tax, gas, revert reason; static checks of its code (owner and renounced, mintable, pausable, blacklist, max tx / wallet, cooldown, tax setters, upgradeable proxy, selfdestruct, ownership reclaim); holders (top 10 share and its part in EOAs, creator / owner share), liquidity and LP burned / held. Verdict ok / caution / danger / honeypot with reasons; each check has a severity (info, warn, danger). Cached 60 s per token. Heavy call.

Daily USD swap volume of an EVM token (both sides of every priced swap), oldest first, up to the indexed head (the last day is partial).

Metadata of up to 100 tokens: symbol, name, decimals, total supply, creator and creation time, logo / description / socials when indexed (launchpad metadata), token family, cross-layer links, spam flag. Unknown addresses come back in `missing`.

Latest trades of a market, newest first. hypercore: fills of a coin (px, sz, side B = buyer aggressor / A, block time). hyperevm / elysium: DEX swaps of a pool (sender, amounts, px = pool price after the swap, USD value). History (hyperevm / elysium): pass trader (a wallet: every swap it sent), pool or token (more than 20 pools: its priced swaps only, `coverage: priced`), optionally side, minUsd (USD at the swap), from / to (Unix ms): newest first, each row with its pool and symbols; filtered pages may hold fewer rows than limit, keep paging with `next_cursor` (null = no more).

One transaction by hash, HyperEVM then Elysium (or layer): status, block, from / to, value, gas and fee (HYPE and USD), decoded ERC-20 transfers, swaps, liquidity events, pools created and NFT transfers, the raw logs we do not decode (from our node), and when it is a bridge leg its legs, matched bridge rows and the cross-layer journey it belongs to. A transaction not indexed yet comes from the node (source: rpc, nothing decoded).

Stop-loss and take-profit orders of one HyperCore market that fired, newest first: wallet, side, trigger and limit price, size (0 = whole position), the order the trigger placed (its status in the trigger block) and its fills there (size, average price, notional). Window: since / until, default the last hour, at most 24 h per call and 7 days back. Named wallets carry `entity`. Next page: pass `next_cursor` as cursor.

One address on HyperCore, HyperEVM and Elysium at once: HyperCore perp account (value, positions with liquidation price) and spot balances, HyperEVM and Elysium token balances and NFTs with USD values, bridge legs in flight and journeys across the layers, latest events (fills, ledger, swaps, transfers, bridges), each section with its freshness. Heavy call; balances alone: get_balances (not heavy).

A wallet's open HyperCore trigger orders (stop-loss / take-profit): coin, side, trigger and limit price, size (0 = whole position), reduce-only, placed at. history: true lists instead every status event of its trigger orders over the last 3 days at most (placed, triggered, canceled, rejected, and the fill or cancel of the order a trigger placed, `triggered: true`), newest first (a heavy call; next page: pass `next_cursor` as cursor).

Deliveries of one webhook, newest first (kept 7 days): msgId (the webhook-id header), type, status pending / delivered / dead, and each attempt with its HTTP status, latency, error and the first 4 KiB of your answer. Next page: pass `next_cursor` as cursor.

Latest moves of named wallets, newest first: HyperCore fills (minNotional USD, default 1000), HyperEVM / Elysium swaps and transfers. Optionally one entity (id from search_entities). Next page: pass `next_cursor` as cursor.

Named wallets ranked by their trading on a layer. hypercore: PnL, volume, fills, win rate, open notional (default 7d, sort netPnl). hyperevm / elysium: swaps, transfers, net buy, holdings, bridge legs (default 24h, sort volume).

Latest token launches, newest first: Elysium launchpad Ascend (default) or HyperEVM LiquidLaunch (launchpad = liquidlaunch). Each: token, pool (pair), creator, priceUsd, mcapUsd, 24 h volume, holders, top-10 / dev share, dev sold, Ascend progress (Elysium). Next page (Elysium): pass `next_cursor` as cursor.

Tradable markets of a layer, most traded first (24 h USD volume). hypercore: perps, spot, HIP-3 dex perps (dex:COIN), outcome markets; `id` is the coin to pass to get_candles / get_trades (BTC, @107, xyz:TSLA). hyperevm / elysium: DEX pools with price, priceUsd, 24 h volume, mcapUsd (Elysium); `id` is the pool key to pass to get_candles / get_trades / get_pool. `total` = markets matching. Next page: pass `next_cursor` as cursor.

Every new pair / pool of every DEX on HyperEVM or Elysium (V2, V3, V4, PancakeSwap Infinity, LiquidLaunch curves…), newest first: dex, factory, fee tier, hooks, both tokens with symbols and whether each was just created (newToken), creation block / tx / time, initial liquidity, current liquidity (V2 / V3 pools: token balances; USD of the priced sides), price, 24 h volume. Pools of a spam token left out. Filters: dex, token (either side), quote, minLiquidityUsd, newTokenOnly, since (ms). Filtered pages may hold fewer rows than limit: keep paging with `next_cursor` (null = no more). Live: WS <layer>.pools.new.

Every ERC-20 created on HyperEVM or Elysium, newest first (not only launchpad launches): creation block / tx / time, creator, the contract it was deployed through, launchpad (ascend, liquidlaunch… or null = direct), first pool (dex, quote, initial liquidity) and, once a pool exists, priceUsd, mcapUsd, liquidityUsd, 24 h volume, holders. Spam tokens left out. Filters: launchpad (name, none, any, 0x), hasPool, minLiquidityUsd, minHolders, creator, since (ms); security=summary adds the cached get_token_security verdict to each row. Filtered pages may hold fewer rows than limit: keep paging with `next_cursor` (null = no more). Live: WS <layer>.tokens.new.

Most active NFT collections of an EVM layer over the last 1 h or 24 h before the indexed head: transfers, mints, burns, with each collection's name, symbol and standard.

Your account's webhooks: URL, state (pending_verification, active, disabled with the reason and how to enable), failures in a row, subscriptions. A rotated key sees the same webhooks. Next page: pass `next_cursor` as cursor.

Send deliveries again, same webhook-id (dedupe on it): one (msgId, delivered or dead), or every dead one since a time (since, Unix ms within 7 days; status all: delivered ones too).

Tokens by symbol, name or address, with their links across layers (Elysium <-> HyperEVM <-> HyperCore), decimals, supply and USD price. Without layer: every layer. An exact address always answers its token (spam flagged).

Named wallets (KOLs, traders, funds, market makers) and their wallets, from public attribution lists (not verified identities). A named wallet's address is given as its handle <entityId>.<hex>, usable as an address in every tool. Use the entity id with kol_activity. Next page: pass `next_cursor` as cursor.

Queue a webhook.test delivery to a verified webhook (not billed); its result shows in get_webhook_deliveries within seconds.
