How this service works
Real-time multi-DEX aggregated crypto market data. Pay per request with USDC on Base via x402 protocol.
Output
A JSON object containing the token symbol, total 24-hour trading volume in USD, a per-DEX breakdown of volume, and a last-updated timestamp indicating data freshness.
Example use cases
Token liquidity check before trade
“Before I swap into PEPE, can you pull the 24-hour DEX volume for PEPE so I can see how liquid it is across exchanges?”
DeFi dashboard live volume feed
“I'm building a DeFi dashboard — fetch the current 24h trading volume for ARB aggregated across all DEXs and show me the per-exchange breakdown.”
Unusual volume spike detection
“Can you check the real-time multi-DEX volume for WIF and tell me if there's been a big spike in activity in the last 24 hours?”
Technical details
Endpoint
GEThttps://api.foursec.xyz/volume/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need real-time, multi-DEX aggregated volume data for a specific crypto token without subscribing to a centralized data provider. It's ideal for pay-per-request, agent-driven workflows using the x402 micropayment protocol on Base, where cost per call ($0.02 USDC) is acceptable and you need per-DEX granularity alongside total volume.
Side effects
- Unknown or unsupported token symbol returns empty or error response
- Payment failure via x402 protocol results in 402 response blocking data delivery
- Stale or delayed data if upstream DEX feeds are lagging
- Malformed symbol path parameter causes 400 or unexpected response
- Rate limiting or network issues at the API gateway level
