Capabilities

Tools 21

get_bonding_curve

Bonding curve analysis: real reserves, virtual reserves, and graduation progress (on-chain). Pre-graduation only: these reserves come from the pump program bonding-curve account, not from a PumpSwap pool. Pump renamed the quote-side fields on-chain (real_sol_reserves -> real_quote_reserves, virtual_sol_reserves -> virtual_quote_reserves) once a non-SOL quote asset became possible; the response keys below keep their original names and are still denominated in SOL, because the curve quote_mint is the SOL default on every coin created to date. A v3 buy that empties the curve completes it and buys the rest through a synthetic migration, priced on the reserves the PumpSwap pool will open with, so a large final buy is not capped at realTokenReserves. Once complete=true the curve is retired and pricing moves to the PumpSwap pool, so use pumpfun_quote_swap from that point on. Use this to read graduation progress or the curve spot price of a coin that has not graduated yet.

Discovered
get_coin_intel

Full Coin Intelligence snapshot for a pump.fun mint. Returns every signal the engine recorded during the observation window: bundle vs organic verdict, bubblemaps-style cluster connectivity, smart-money presence (with wallet labels and win-rates), dev behaviour, category/classification, news-meme detection with the matching headline, risk flags, and a 0-100 quality score. Also returns the outcome if the coin is old enough to be labeled (graduated/rugged/ATH multiple). This is the single highest-signal read for a trade decision. Call this before entering any position.

Discovered
get_new_tokens

Most recently launched pump.fun tokens. Use this to catch launches in their first minutes; for the largest coins by market cap call get_trending_tokens instead.

Discovered
get_oracle_conviction

Oracle conviction score for a pump.fun mint: the fused 0-100 score the Oracle engine produces by combining four intelligence pillars: pedigree (who bought it), structure (organic vs bundle, holder concentration, bubblemaps connectivity), narrative (category, meme virality, news hook), and momentum (timing, velocity). Returns the tier (prime ≥86 / strong ≥72 / lean ≥54 / watch ≥36 / avoid), the per-pillar breakdown, the natural-language reasons that drove the score, the full "who's in" trader roster with reputation labels and win-rates, and the narrative read (category, virality, tags). Call this when you need the highest-confidence trade signal; it synthesises everything get_coin_intel exposes into one actionable score. Pairs with get_coin_intel for raw signals.

Discovered
get_token_details

Full details for a specific pump.fun token by mint address. Use this when you already have a mint and need its metadata, market cap, and curve status; for holder concentration call get_token_holders, for recent fills call get_token_trades.

Discovered
get_token_holders

Top holders of a token with concentration analysis (on-chain). Use this to check whether a few wallets control the supply before buying; for price and volume call get_token_details instead.

Discovered
get_token_trades

Recent buy/sell history for a token. Use this to read recent buy and sell flow on one coin; to see only large trades as they land, call pumpfun_watch_whales instead.

Discovered
get_trending_tokens

Top pump.fun tokens by market cap. Use this to scan the largest coins on pump.fun right now; for fresh launches call get_new_tokens, for coins that left the curve call get_graduated_tokens.

Discovered
kol_leaderboard

Top KOL traders ranked by P&L for a given time window. Returns wallet, pnlUsd, winRate, trades, rank. Use this to find which trader wallets are worth following; to see whether they hold a given coin, call get_coin_intel or get_token_holders.

Discovered
pumpfun_bot_status

Returns the configuration and health status of the pump.fun indexer backend. Always available; does not require PUMPFUN_BOT_URL. Use this first when search_tokens, get_graduated_tokens, get_king_of_the_hill, or get_creator_profile fail or are missing, to see whether the indexer is configured and healthy.

Discovered
pumpfun_first_claims

First-ever pump.fun creator fee claims in a time window: a cash-out signal. Returns creators who have never claimed before, with creator wallet, mint, lamports, and timestamp. Use this to spot creators cashing out for the first time across all coins; for one creator's history call pumpfun_list_claims.

Discovered
pumpfun_list_claims

List recent pump.fun fee-claim events for a creator wallet (on-chain, no indexer needed). Returns signature, mint, lamports, and Unix timestamp for each claim. Creator fees from the v3 curve and v2 pool trades wait on the curve and pool until a sweep_creator_fee moves them to the creator vault, so a claim covers only what was swept (usually in the same transaction) and fees still waiting appear in no claim yet. Use this to audit how much a creator has already cashed out; for only the claims inside a recent window call pumpfun_watch_claims.

Discovered
pumpfun_quote_swap

Read-only price quote for a pump.fun AMM (PumpSwap) swap. No signing or tx sending. One of inputMint/outputMint must be wSOL (So11111111111111111111111111111111111111112). Only GRADUATED coins have an AMM pool; for a coin still on its bonding curve use get_bonding_curve instead. Pricing runs on the pool effective quote reserves (quote vault balance + pool.virtual_quote_reserves, a SIGNED i128 that is commonly negative because PumpSwap v2 trades keep waiting protocol and creator fees in the vault and subtract them there); the base side is the raw base vault balance. Returns amountOut, priceImpactBps, route, expiresAtMs, plus the reserves the quote was computed from so the number can be reproduced. Use this to size a trade on a graduated coin, or to measure its pool depth, before executing anywhere.

Discovered
pumpfun_upload_metadata

Upload coin metadata (name, symbol, description, image) to IPFS and get back a pump.fun-ready metadata URI. Call this before launching a coin: pass the returned uri to the launch-agent endpoint or the studio launch flow. Requires a valid bearer token (API key). Image may be a public HTTPS URL or a base64 data URI (max 10 MB). The returned uri is a permanent ipfs:// link; the call is idempotent for the same content.

Discovered
pumpfun_vanity_mint

Generate a Solana keypair whose address ends/starts with a vanity pattern. Returns publicKey + secretKey (base58). Caller must save the secret key immediately; it is never stored. Hard timeout: 60 s. Use this before launching a coin when its mint address should carry a recognizable prefix or suffix.

Discovered
pumpfun_watch_claims

Return all pump.fun fee-claim events for a creator wallet within a look-back window (durationMs). Use this for batch collection after a delay; for a creator's full recent claim history call pumpfun_list_claims.

Discovered
pumpfun_watch_whales

Collect whale trades on a pump.fun token for a short window (max 10 s). Returns all trades whose USD value meets minUsd. Use this to see who is moving size on a coin right now; for the full recent tape call get_token_trades.

Discovered
sns_resolve

Resolve a .sol Solana Name Service domain to its owner wallet address. Use this when a wallet is named by its .sol domain and you need the address; for the reverse direction call sns_reverseLookup.

Discovered
sns_reverseLookup

Reverse-lookup a Solana wallet address to its primary .sol domain name. Use this to label a raw wallet address with its human-readable .sol name; to go from name to address call sns_resolve.

Discovered
social_cashtag_sentiment

Score social-post sentiment for a cashtag using a deterministic lexicon. Returns score (-1..1), positive/negative/neutral percentages, and example posts. Use this to score posts you have already collected; it fetches nothing itself, so pass the posts in.

Discovered
social_x_post_impact

Correlate an X (Twitter) post to a memecoin price impact. Fetches post metadata via oEmbed (no API key) and computes price delta from the pump.fun bonding curve in a ±windowMin window around the post. Use this to measure how one X post moved a coin that is still on its bonding curve (pricing is virtual_quote_reserves / virtual_token_reserves); a graduated coin has no curve, so the call fails rather than returning a zero price.
