Token Risk Check – Deployer History & Rug Verdict is a paid API for AI agents from onchaincheck.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).
Looks up a token deployer's full launch history and returns a rug-pull risk verdict (repeat-rugger, prior-rug, serial-launcher, clean-so-far, too-new) with per-token risk scores and liquidity survival data at 24h and 7d.

How this service works
Who launched this token, and what happened to their other tokens? A creator's launch record on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana from our own history of new pools: every token the wallet launched since 2026-10-23 with its risk score at launch and whether its liquidity was gone 24 hours and 7 days later, plus a verdict (repeat-rugger, prior-rug, serial-launcher, clean-so-far, too-new). Pass the deployer wallet or a token address. Not advice.
Output
Returns the deployer wallet address, a list of every token they launched since 2026-10-23 with each token's risk score at launch, whether liquidity was present 24 hours later, whether liquidity survived 7 days, and a summary verdict label: repeat-rugger, prior-rug, serial-launcher, clean-so-far, or too-new.
Example use cases
Vetting a new meme coin before buying
“Before I ape into this Base token at 0x1234567890abcdef1234567890abcdef12345678, can you check who deployed it and whether they've rugged tokens before? I want their rug verdict and liquidity history.”
Flagging a repeat rugger in a Telegram alert bot
“Someone just shared a new Solana token — the deployer wallet is 9xQy3ZvLmRkPw2N8TbKj5HsDeFaQ7rVxCnBpJtYoMiAe. Pull their full launch history and tell me if they're flagged as a repeat-rugger or serial-launcher.”
Due diligence on an Ethereum token creator
“I'm looking at a new ERC-20 on Ethereum — can you look up the deployer 0xAbCd1234EfAb5678Cd9012EfAb3456Cd7890AbCd on the eth chain and tell me how their previous token launches went, specifically whether liquidity survived 7 days?”
Technical details
Endpoint
GEThttps://onchaincheck.dev/deployer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a historical track record of a token deployer rather than just a point-in-time risk score for a single token. It is the right choice when assessing whether a wallet is a serial rugger across multiple launches, or when you want to know if liquidity actually survived 24h and 7d on prior tokens. Prefer this over single-token risk checks when performing deployer-level due diligence before buying into a new launch.
Side effects
- Invalid address format — address doesn't match EVM (0x…) or base58 Solana pattern
- Token address provided but deployer lookup fails — contract may be unverified or not indexed
- No launch history found — deployer has no tokens recorded since 2026-10-23 (too-new verdict)
- Unsupported chain specified — must be one of base, eth, arbitrum, optimism, polygon, solana
- Payment failure — x402 micropayment of $0.005 USDC not completed or rejected
- Rate limit or server error — 5xx response
