Plexa Rug Check — Pre-Trade Token Safety Check
x402
Plexa Rug Check — Pre-Trade Token Safety Check is a paid API for AI agents from api.getplexa.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).
Checks whether an ERC-20 token on Base (or supported L2s) is provably unsellable right now by detecting on-chain traps: no liquidity pool, insufficient exit liquidity relative to trade size, or a disabled trading gate (honeypot pattern).

How this service works
Plexa /v1/pretrade/check — pre-trade token safety check on Base: can you still sell this token? avoid fires only on a trap proven on-chain now: no pool to exit into, an exit pot under 5% of your size, or the trading gate off (the honeypot shape). A drained pot is what a rug leaves behind — measured, not predicted. clear = no provable trap, NOT safe. Alias: same engine and price as /v1/pretrade/check.
Output
Returns a structured verdict indicating whether a provable on-chain trap exists for the token: flags for no liquidity pool, insufficient exit liquidity relative to the requested USD size (under 5% threshold), or a disabled trading gate (honeypot). Also returns an executable quote sub-result calibrated to the requested sizeUSD. A 'clear' result means no provable trap was detected — explicitly not a safety guarantee.
Example use cases
Pre-buy honeypot check for new token
“I'm about to ape into this Base token at 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234 with $5000 — can you check if the trading gate is disabled or if it's a honeypot before I pull the trigger?”
Exit liquidity check for large position
“I'm holding 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefd2 on Base and want to sell my $15000 position — is there enough exit liquidity in the pool right now, or would I be trapped?”
Automated bot pre-trade safety filter
“Before my sniper bot buys 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base with a $500 notional, do a rug check to make sure there's no provable trap — no locked pool, no trading gate off, nothing like that.”
Technical details
Endpoint
POSThttps://api.getplexa.com/v1/rug-checkWhen to prefer
Use this endpoint when you need a fast, on-chain-provable pre-trade safety check specifically on Base (or supported L2s) before executing a token buy. Prefer it over generic token scanners when you need an objective, measurable verdict (no pool, insufficient liquidity, trading gate off) rather than a predictive or heuristic score. Especially valuable for automated trading bots or agents that need a programmatic go/no-go signal tied to a specific USD position size.
Side effects
- 400 — token parameter is a symbol (e.g. 'WETH') instead of a 0x hex address
- 422 — non-Base chain specified (chains other than Base currently not supported for calibrated safety flags)
- Invalid sizeUSD format — comma-separated numbers or non-numeric strings are rejected
- Malformed token address (not matching 0x + 40 hex pattern)
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chain | string | Optional, default "base". One of: base | polygon | matic | arbitrum | arbitrum-one | arb | eip155:8453 | eip155:137 | eip155:42161 — case-sensitive (see `enum`). The safety flags are Base-tuned, so a non-base value currently answers 422 rather than returning Base-calibrated flags for another chain. |
| token | string | ERC-20 to vet before buying. 0x + 40 hex (see `pattern`) — a symbol like "WETH" is rejected with 400. |
| sizeUSD | string | Optional USD notional for the executable-quote sub-result, default "1000". A STRING, not a number; positive, no thousands separator ("1,000" is rejected) — see `pattern`. |
