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. risk_profile: token age, holder concentration, liquidity, transfer limits. Not financial advice.
Output
A structured verdict object containing: a top-level safety rating (ok/caution/avoid), breakdown of liquidity structure, holder concentration metrics, token age, honeypot and fee-on-transfer detection flags, oracle price sanity result, and an executable swap quote for the requested USD notional size.
Example use cases
Example prompt
“Before I buy, can you run a Plexa pre-trade safety check on this Base token — 0x1234567890abcdef1234567890abcdef12345678 — for a $2000 position, and tell me if it's ok, caution, or avoid?”
Technical details
Endpoint
POSThttps://api.getplexa.com/v1/pretrade/checkWhen to prefer
Use this endpoint when an AI agent or user wants to vet an unknown or suspicious ERC-20 token on Base before executing a trade — especially when honeypot detection, holder concentration, liquidity depth, and an actionable price quote are all needed in a single call. Prefer this over generic price feeds or DEX aggregators when safety/risk assessment is the primary concern, not just price discovery.
Side effects
- Invalid or non-Base ERC-20 address returns a 400/422 error
- Token too new or insufficient on-chain data may yield an inconclusive verdict
- Oracle data unavailable for illiquid tokens
- Network congestion on Base may delay quote freshness
- Payment failure (insufficient USDC or x402 protocol error) blocks the call
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`. |
