How this service works
Token liquidity and momentum snapshot, half a cent: live DEX liquidity in USD, price, market cap, pair age, 1h/24h volume, buy-vs-sell transaction ratio, price change — the raw DexScreener read for any EVM token, one source, no fusion. Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche. Cheapest pre-trade depth check; upgrade to /api/evmtoken ($0.015) for the fused safety verdict or /api/exit-depth for sell-impact modeling.
Output
Returns a real-time snapshot of DEX market data for the requested EVM token, including: live USD liquidity depth, current token price, market cap, trading pair age, 1-hour and 24-hour volume, buy-to-sell transaction count ratio, and recent price change percentage — all sourced from DexScreener with no data fusion or safety scoring applied.
Example use cases
Pre-trade liquidity check on Base
“I'm about to ape into this Base token at 0x1234abcd... — can you quickly check its current DEX liquidity in USD, 24h volume, and buy/sell transaction ratio so I know if it has enough depth before I put money in?”
Momentum scan for Arbitrum token
“Pull the latest DexScreener snapshot for this Arbitrum token 0xdeadbeef... — I want to see the price, 1h and 24h volume, price change, and how old the trading pair is.”
Market cap and pair age lookup on Ethereum
“What's the current market cap, price, and pair age for this Ethereum token 0x7a250d5... on DEX? Also show me the buy vs sell ratio from the last 24 hours.”

Endpoint
GEThttps://onchainpulse.theaslangroupllc.com/api/facet/liquidity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.005), fast, raw DexScreener liquidity read for a single EVM token on supported chains — ideal as a pre-trade depth check before committing capital. Prefer this over /api/evmtoken ($0.015) when you only need market data and do not need the fused safety/honeypot verdict. Use /api/exit-depth instead if you specifically need sell-impact modeling for large exits.
Side effects
- Token address not found on the specified chain — returns empty or error response
- Token exists but has no active DEX pair — liquidity data unavailable
- Unsupported chain provided — only Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche are supported
- DexScreener upstream outage — stale or missing data
- Malformed token address — request validation error
- Very new token with insufficient trading history — pair age and volume fields may be zero or null
