Measured tools (34)

token_check read-only
Free. Coarse pre-trade rug check for one token: a Solana mint or link, or a Robinhood Chain pons 0x address or link. Returns verdict (avoid | caution | no_flags_observed), a reason and coverage; any other Solana mint gets a thin on-chain answer, never avoid on that evidence. Not a safety verdict. Next: verdict $0.01, mint_risk_card $0.025, rhc_curve_card $0.02. Use it first before you buy.
Parameters:
- mint — string — Alias of token, either name works: takes a mint or a pump.fun/gmgn/solscan/birdeye link, or a pons 0x address.
- token — string — The token to check. Solana: a mint or a pump.fun/gmgn/solscan/birdeye link (a base58 SPL or Token-2022 mint, 32-44 chars; a link is resolved to its mint). Robinhood Chain: a pons v2 curve or token address (0x + 40 hex), or its pons link (www.ponsfamily.com/launchpad/<token>) or explorer link (robinhoodchain.blockscout.com/token/<token>).
Hints: read-only yes · destructive no · idempotent yes · open-world yes
catalog read-only
Free. Start here: every tool with its price, arguments and x402 payment terms (USDC on Solana or Base), plus the label semantics URL. Use it first to choose a tool and budget; it carries no market data.
Hints: read-only yes · destructive no · idempotent yes · open-world yes
health read-only
Free. Feed health: feed_lag_s (seconds behind the newest event), is_stale, last Solana slot, chain_lag_s and slots_behind (how far the tape is behind the chain, estimated from slots against the Solana RPC's processed tip). Use it before trusting a card's freshness.
Hints: read-only yes · destructive no · idempotent yes · open-world yes
market_regime read-only
Free. pump.fun market regime: launches and curve buys and sells per minute, mayhem share, migrations vs true graduations, rug flags per hour. Use it to judge the market as a whole; for one mint use check_pumpfun_risk. No arguments.
Hints: read-only yes · destructive no · idempotent yes · open-world yes
sample_mint read-only
Free. One full risk card (the exact paid mint_risk_card shape) for a mint aged >= 300 s with >= 3 buys, delayed. Use it to see every field before paying; the server picks the mint, so it is not a check on yours. No arguments.
Hints: read-only yes · destructive no · idempotent yes · open-world yes
new_launches_free read-only
Free. New Solana tokens ranked: ten covered pump.fun mints under 30 s old by P(rug within 300 s) and ten under 15 min by P(true graduation), refreshed every 5 s, each with its paid check. Use it to find new memecoin launches worth a paid check. No arguments.
Hints: read-only yes · destructive no · idempotent yes · open-world yes
check_coverage read-only
Free. Whether one to five pump.fun mints have full live coverage and a fresh feed (<= 5 s), with the exact prices. Use it right before a paid check; it returns no risk findings.

watchlist_updates read-only
Free. Start or poll a watch cursor for one to five mints: whether new risk or lifecycle events exist, not what they are (a paid check returns them). Cursor lasts 24 h; poll every 15 s or slower. Use it to watch held mints without paying.
Parameters:
- mints (required) — array — One to five distinct pump.fun mints with full live coverage, each a mint or a pump.fun/gmgn/solscan/birdeye link
