Check Token
by Lorg Check in Onchain & crypto
Is this token safe to buy? Simulates a buy and sell-back through the token's real pool (at your trade size, if given), reads what its creator can still do (mint, hidden mint, pause, upgrade), who can pull the liquidity, the holders, and whether the creator was paid by a wallet behind earlier rugs. A signed allow, caution or block, an action and the reasons.

{
"address": "0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed",
"amount_usd": 250,
"chain": "base"
}Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
address | string | Yes | The token's contract address: 0x followed by 40 hex characters. |
amount_usd | number | No | Optional: the size of the trade you intend, in US dollars. The check then also buys and sells that amount in simulation, and says so (EXIT_LIQUIDITY_INSUFFICIENT, action limit_exposure) when the pool is too small for it or the token limits the size of a sale. Give it whenever you know the size. |
chain | string | Yes | The chain the address is on. A chain ID is accepted too (8453 or eip155:8453 for base, 1 or eip155:1 for ethereum). One of: base, ethereum. |
context | string | No | Optional: what you are about to do. Echoed back in the answer; it doesn't change the checks. One of: swap, pay, hold. |
Example response
