Elysium launchpad API

Launch data API for Elysium, Kinetiq's Hyperliquid L2 (chain 99901): Ascend, Montra, Boxa, Kleos and 74 more launchpads, plus every bonding curve and pool launch found on chain. Curve progress, graduation, REST, WebSocket, webhooks, MCP.

Elysium is Kinetiq's Hyperliquid L2 (Arbitrum Orbit on HyperEVM, chain 99901). Femtos indexes the launches of every launchpad on its mainnet: 78 launchpads by name, and every bonding curve or pool launch found on chain with no integration. One call lists them all, with curve progress, graduation and live market figures.

Base URL https://api.femtos.xyz/v1, key in Authorization: Bearer; WebSocket wss://api.femtos.xyz/v1/ws; MCP https://api.femtos.xyz/mcp. Decimals are exact strings, times Unix ms.

Launchpads covered (78)

A launch names its launchpad in launchpadRef.name. Pass that name as launchpad to list the launches of one launchpad; launchpad=any lists every launchpad, launchpad=unknown the launches found on chain that no launchpad of the list names.

Every launchpad ranked

/v1/launchpads lists every launchpad with its launches over 24 hours, 7 days and all time, its tokens on their curve and graduated, the graduation rate, the 24 h volume of its tokens and its top token. /v1/launchpads/{name} gives one launchpad the same figures and its launches and graduations per day over 30 days.

curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/launchpads?layer=elysium&sort=volume24h"

Launches with no integration: the indexer infers a bonding curve from a token's first trades (the contract holding most of the minted supply, trading it for HYPE), and a pool launch from its creation transaction (the whole supply seeded into a DEX pool).

What a launch row carries

launchpadRef.basis says how the launch is known: event, the launchpad's own launch event (Ascend Launched); inferred, found by the indexer. status is curve, graduated or pool; curve.progress goes from 0 to 1 toward graduation.

Example

The launches still on their bonding curve, nearest to graduation first:

curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/launches?launchpad=any&status=curve&sort=progress&limit=20"

Shape of a row (the answer is an array; the next page is in the Link header):

// an array of rows
{
  token: string;
  symbol: string | null;
  launchpadRef: { name, address, basis, nameBasis, kit, label, selfLaunch };
  status: curve | graduated | pool;
  curve: { address, progress, progressBasis, reserveHype, tokensOnCurve } | null;
  graduation: { block, at, tx, pair, protocol } | null;
  pool: { id, protocol, kind };
  priceUsd: decimal | null;
  mcapUsd: decimal | null;
  holders: int;
}

Parameters of GET /v1/launches

Every launch call

• Launchpads ranked GET /v1/launchpads
  Every Elysium launchpad ranked by launches, graduations or 24 h volume, with its top token.
• One launchpad GET /v1/launchpads/{name}
  One Elysium launchpad's figures and its launches and graduations per day over 30 days.
• Launches GET /v1/launches
  Latest launches of every launchpad (Ascend and every bonding curve), with curve progress, graduation and live market figures.
• Launch detail & signals GET /v1/launches/{token}
  Metrics, dev wallet, early buyers and risk signals of one launch.
• Launch timeline GET /v1/launches/{token}/timeline
  The whole life of a launch as ordered events with running state.
• Launch holders GET /v1/launches/{token}/holders
  Every holder of a launched token, tagged dev or early buyer, with concentration.
• New tokens GET /v1/tokens/new
  Every ERC-20 created on Elysium, newest first, with its first pool and market figures.
• Chain launches GET /v1/activity/launches
  Elysium tokens launched on a launchpad and ERC-20 tokens created (spam left out), per bucket.
• Launches stream WS elysium.launches
  One message per new launch of any launchpad, the moment its block is indexed; with updates, one more each time a launch trades on its curve, trades for the first time or graduates.
• New tokens stream WS elysium.tokens.new
  One message per new token as its block is indexed, and another when its first pool opens; with updates, one more each time a new token trades.

Webhooks

The elysium.launches channel delivered to your HTTPS URL: create a webhook with POST /v1/webhooks and a subscription to that channel, with the same launchpad filter. Signed (Standard Webhooks), retried.

• Webhooks
  Channels, signatures, retries, limits.

MCP

Agents call the same data as tools of the hosted MCP server:

More

• Launch story
  One launch told event by event: dev wallet, early buyers, swaps, holders.
• Elysium token price and OHLCV API
  Token prices, price history and OHLCV candles.
• Elysium data API
  Everything served on Elysium, by group.
• MCP server
  Connect Claude, Cursor or any MCP client.
