How this service works
VAPE liquidity_check — Liquidity depth + top pair DEX for a Base token. Real on-chain/market data, no simulation.
Output
Returns a JSON object containing the contract address, a safety verdict (e.g. PROCEED or CAUTION/AVOID), the top DEX pair for the token (e.g. Aerodrome), and total liquidity in USD. Agents can use the verdict field to gate trade decisions programmatically.
Example use cases
Pre-trade token safety check
“Before I swap into this token at 0x4200000000000000000000000000000000000006 on Base, can you run a liquidity scan and tell me the verdict and total liquidity in USD?”
DeFi research on new Base token
“I found a new token on Base at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — can you check which DEX has the best liquidity for it and whether it's safe to proceed?”
Rug-pull risk screening
“I'm worried this token might be a rug — can you do an on-chain liquidity audit on 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base and give me a safety verdict?”
Technical details
Endpoint
GEThttps://vape-x402.vapex402.workers.dev/scan/liquidity_checkWhen to prefer
Use this endpoint when you need a fast, pay-per-call liquidity and safety check on a specific Base chain token before executing a trade or recommending an investment. Prefer it over generic block explorer lookups when you need a structured verdict and USD liquidity figure from a DEX-aware scanner without requiring your own RPC infrastructure.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Address is on the wrong chain (non-Base) and chain override not provided — may return no data
- Very low-liquidity or newly deployed tokens may return zero liquidity values
- Network timeouts from on-chain RPC calls may cause delayed or failed responses
- Payment failure ($0.02 USDC via x402) prevents the scan from executing
