USD price for up to 50 Solana token mints in one call from Jupiter's price API v3: price, 24h change, liquidity, decimals and the block the price was read at. Mints Jupiter does not price come back listed under missing rather than erroring the batch. Pass mint addresses, not tickers (resolve tickers with sol-token-search or sol-token-lookup). Keyless.

Executable swap quote on Solana from Jupiter's aggregator: input and output mint, amount in base units, slippage in bps - returns out amount, minimum out after slippage, price impact percent, the routed DEX labels in hop order with split percentages, the USD value of the swap and the context slot. A real multi-hop route across Solana DEX liquidity, so the number reflects depth, not a spot price. Quote only - nothing is signed or sent. Keyless.

Top-holder concentration for a Solana token mint: the 20 largest holders with token account, owner wallet, balance, percent of supply, insider flag and a pool/locker label when the account is a known AMM vault or locker, plus top-1/5/10/20 share, top-10 share excluding labelled pool accounts, insider count, total holder count and supply. Use it to tell a whale-held launch from one whose largest holder is the liquidity pool.

Resolve a Solana token by mint, ticker or name through Jupiter's token index and get its profile in one read: name, symbol, decimals, price, market cap, FDV, liquidity, holder count, circulating and total supply, verified flag, organic score (Jupiter's wash-trade-resistant activity score), tags, launchpad, dev wallet, first pool and date, audit facts (mint and freeze authority disabled, top-holder share, dev mints) and 24h stats (price, holder and liquidity change, buy/sell volume, traders, net.

Every DEX pair trading a Solana token mint (Raydium, Orca, Meteora, Pump.fun AMM and the rest), sorted by liquidity: pair address, DEX, price in USD and in the quote token, liquidity, FDV and market cap, 5m/1h/6h/24h volume and price change, buy/sell transaction counts, pair age in hours, plus totals across pairs. One DexScreener request, keyless.

Full RugCheck report for a Solana token mint, trimmed to what an agent acts on: score and risks, mint/freeze authority state, metadata mutability and update authority, supply and decimals, creator and creator balance, top 20 holders with percent, owner, insider flag and pool/locker labels, concentration totals, the deepest markets (liquidity, LP locked %), lockers, total market liquidity, LP providers, holder count, rugged flag, insider-network count, launchpad and transfer-fee config.

Safety verdict for one Solana token mint: a graded risk score with the concrete reasons behind it, mint and freeze authority state, how much of the liquidity pool is locked, top-holder concentration, holder count and whether the token is verified. Use it before an agent buys, quotes, or recommends an unfamiliar token, and to screen a list of mints in seconds.

Find Solana tokens and pairs by name, ticker or address across every DEX DexScreener indexes, filtered to Solana only, in DexScreener relevance order: base and quote token, mint addresses, DEX, price, liquidity, 24h volume and change, transaction counts, pair age and whether the token has a filled-in profile (ticker impostors usually do not). Resolve a ticker to a mint before calling sol-token-safety or sol-swap-quote. Keyless.

What Solana tokens are being pushed right now: DexScreener's top boosted tokens (paid promotion, ranked by boost amount - a signal of marketing spend, not quality) and the latest token profiles (fresh listings with a filled-in profile), both filtered to Solana. Each row carries the mint, DexScreener URL, description snippet and links. Feed the mints into sol-token-safety to separate the promoted from the sound. Keyless; two small DexScreener reads in parallel.
