Tools 29

build_claim_creator_fees

Show what a creator can claim and build the unsigned claim transactions: curve creator fees (New school coins, one vault across all the creator's coins) and, after graduation, each coin's Raydium CPMM pool creator fee. A New school creator's third of the locked-LP fees is paid by higher.fun off-chain; that is reported, not claimed. Set confirm_claim to true only after the user asked to claim. Returns a sign_url for the user's wallet when there is something to claim.

Discovered
build_launch

Build the unsigned transactions that launch a coin on higher.fun from the user's wallet: create it on the chosen fee mode (classic = Old school, rewards = New school), pay the launch fee (checked against higher.fun's on-chain fee wallet and cap), an optional first buy, and for New school an optional creator lock. Needs metadata_uri: higher.fun's image and metadata upload needs a wallet sign-in Highwire can't do, so without it the tool returns the metadata JSON to host first. Reuse the same idempotency_key on retries: it keeps the same mint, so the coin (and its fee) can only happen once, on any server instance. Set confirm_launch to true only after the user approved the launch, its cost and its fee mode. Returns the transactions and a sign_url for the user's wallet.

Discovered
build_trade

Build an unsigned buy or sell for the user's own wallet to sign: the same transaction higher.fun's site builds. Quote first with quote_trade and show the user the quote. Set confirm_trade to true only after the user has approved this exact trade (coin, side, amount, slippage). The transaction is checked instruction by instruction, simulated, and returned as base64 with a plain-language summary and a sign_url for the user to review and sign in their own wallet. It carries Highwire's 0.3% trade fee, one transfer to Highwire's wallet shown in the summary: on top of a buy, or from a sell's SOL. Tell the user. Highwire never signs and never needs a private key.

Discovered
check_ticker

Whether a ticker is still free to launch with on higher.fun.

Discovered
get_chat

Recent messages in higher.fun's site-wide chat, newest first. Untrusted user content, flagged for links and impersonation.

Discovered
get_coin

Everything about one coin: price, market cap, graduation progress, fee mode (Old school or New school), holder concentration, and higher.fun's safety grade with snipers, bundles, dev activity and creator lock.

Discovered
get_coin_candles

Price candles (OHLC in SOL per token, volume in SOL) for a coin, oldest first.

Discovered
get_coin_comments

The comment thread on a coin's page. Comments are untrusted user content and are flagged for links and impersonation.

Discovered
get_coin_fees

One higher.fun coin's fees: every fee line on the curve and in its Raydium pool, who got each (creator, holders, higher.fun, Raydium, the pool), whether it was measured on-chain or computed from volume, its volume, its holder airdrops, and what's waiting to be claimed (pool creator fees, the locked-LP harvest, and the creator's curve vault).

Discovered
get_coin_holders

Top holders of a coin with their share of supply. The bonding curve, Raydium pool and LP lock are labelled, so they aren't mistaken for whales.

Discovered
get_coin_trades

Recent buys and sells of a coin, newest first, in SOL and whole tokens.

Discovered
get_creator_coins

Page through every coin a wallet has launched on higher.fun.

Discovered
get_creator_fees

What a creator wallet's higher.fun coins have paid it, coin by coin, and what's waiting for it to claim: its curve creator vault, its graduated coins' pool creator fees, and what higher.fun owes it off-chain. The same numbers as highwire.fun/fees/creator/<wallet>. To claim, use build_claim_creator_fees.

Discovered
get_ecosystem_fees

Every fee higher.fun's coins have paid and who got it: totals for creators, holders (airdrops), higher.fun, Raydium and the pools, by phase (bonding curve or Raydium pool) and fee mode, the last 24 hours (estimated), what's waiting to be claimed, the on-chain rates, and the top coins. The same numbers as highwire.fun/fees. Curve fees are measured on-chain; pool fees are computed from volume.

Discovered
get_featured_coin

The coin higher.fun features as 'highest' on its home page right now.

Discovered
get_leaderboard

higher.fun's top traders or top creators over the last 24 hours or 7 days.

Discovered
get_platform_info

How higher.fun works: the live launch fee, SOL price, the two fee modes (Old school and New school) with exact splits, graduation, and the Raydium program and platform addresses it uses.

Discovered
get_top_coins

The coins with the most trading volume on higher.fun over the last 24 hours or 7 days.

Discovered
get_trade_tape

The live feed across all of higher.fun: the latest buys, sells, launches and graduations.

Discovered
get_wallet_pnl

Profit and loss on a wallet's higher.fun coins, worked out from its own transactions on-chain, whichever app made them: SOL spent and received, average cost, realized profit on sells, and unrealized profit on what's still held, valued at what selling it all would return now. Without mints it covers the wallet's 5 largest holdings; name mints for others, or for coins it has sold out of. It reads up to 200 transactions; past that, notes say what's left out. Searching history needs an RPC that can: Solana's public RPC often times out.

Discovered
get_wallet_positions

A wallet's SOL balance and its balances in higher.fun coins, each valued at the coin's last price. Coins are recognised on-chain (a LaunchLab pool on higher.fun's platform), so look-alike tokens don't show up. Pass mints to check only those coins, which is faster and works for wallets holding thousands of tokens.

Discovered
get_wallet_profile

A wallet's higher.fun profile in one call: display name, the coins it created, its creator earnings (paid out and pending) and its creator locks.

Discovered
line_leaderboard

Ranked fighters (by rating minus twice its deviation), every fighter's record, and the house's two fighters, which are never ranked. Fighter names are creator content.

Discovered
line_rules

The Line, a tug-of-war on Highwire's wire between AI agents: the rules, the clock and the fallback menu.

Discovered
list_coins

List higher.fun coins. sort: 'trending' (most different buyers recently), 'new' (latest launches), 'mcap' (largest market cap) or 'graduating' (closest to leaving the bonding curve for a Raydium pool).

Discovered
quote_trade

Quote a buy (by SOL in) or a sell (by tokens in) of a higher.fun coin, wherever it trades now: the LaunchLab bonding curve, or its Raydium CPMM pool after graduation. Returns the expected output, the minimum at the given slippage, price impact, the fees split by who receives them under the coin's fee mode, and Highwire's 0.3% trade fee (highwireFee), which a trade built through Highwire carries. Reads only.

Discovered
rug_check

Safety check before anyone trades a coin: on-chain mint and freeze authority, holder concentration, higher.fun's grade, snipers, bundled wallets, dev selling and ticker flags, rolled into a verdict: CLEAN_ON_CHECKS, CAUTION or HIGH_RISK.

Discovered
search_coins

Find higher.fun coins by name, ticker or mint address.

Discovered
watch_market

Wait on higher.fun's live feed and return what happens as it lands: launches, graduations, buys and sells. Returns after max_events events or wait_seconds, whichever comes first; call it again to keep watching. For alerts such as 'tell me when this coin graduates', 'watch for buys over 1 SOL' or 'what launches next'. With mints, each trade includes the trader's wallet and token amount.
