Rug pull probability

get_rug_score

Read-onlyIdempotent

Rug pull probability for one token: a 0-100 score where HIGHER MEANS MORE DANGEROUS, a verdict label, and the individual signals that drove it. This is the opposite direction from get_token_scan's safety score. Call this tool ONLY when the user explicitly asks for a rug probability or rug likelihood; every general "is this safe" or "should I buy" question goes to get_token_scan instead. Not for the evidence behind the number — it names the signals but does not list the wallets; for who is behind the risk call get_wallet_links, get_dev_tracker or get_launch_bundles. Arguments: address and chain; one API unit on any chain.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`chain`	No	Chain the token is deployed on: solana (default), ethereum, base, bsc, robinhood, arc, hyperevm. Required for any 0x address, because the same contract address can exist on several EVM chains. Omit it for Solana. An unsupported value is rejected before any request is spent; EVM chains need a key on an All-Chains plan.	solana
`address`	Yes	The token's own contract address, exactly as an explorer shows it. Solana: the base58 mint, 32-44 characters (e.g. 6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN). EVM: 0x followed by 40 hex characters, case-insensitive (e.g. 0x6982508145454ce325ddbe47a25d4ec3d2311933). Never a pool, pair, wallet or deployer address — those come back as not found. Set `chain` to match the address: a 0x address alone cannot say which EVM chain it lives on, and a Solana mint sent with an EVM chain is rejected.

Output Schema

TableJSON Schema

Name	Required	Description
`token`	No	The address that was scanned (on get_token_scan, the full token metadata object instead).
`fusion`	No	Cross-signal wallet correlation; wallets list is empty on non-Pro keys.
`signals`	No	Each contributing signal: what fired, its weight and its explanation.
`verdict`	No	PROBABLY SAFE (<25), SOME RISK (25+), ELEVATED RISK (45+), HIGH RISK (60+), EXTREME RISK (75+); or a state that overrides the bands: RUGGED / DEAD, ABANDONED / DEAD, NEVER BONDED (a launchpad coin that never left its bonding curve — no pool ever existed; rugScore is still returned as a number).
`coverage`	No	"full" when the Pro signal set contributed, "free" when only the free signals did — a "free" score has seen less evidence. ("partial" only appears on the raw API when a caller declines to wait; this tool always waits for the complete answer.)
`rugScore`	No	Rug probability 0 (safe) to 100 (critical). HIGHER IS MORE DANGEROUS.
`poweredBy`	No	Always "DeFade.org".
`timestamp`	No	ISO time the response was assembled.
`scoreLabel`	No	Null normally. "NEVER BONDED" when the human surfaces print that state instead of the percentage; rugScore is still the number.
`bundleSubScore`	No	The bundle component of the score.
`proChecksLocked`	No	How many Pro-only checks were withheld.
