How this service works
A token on several Base DEXes should cost about the same on each; a gap is either an arbitrage window or, on a thin pool, a mispricing that signals wash/manipulation. Compares the price across the LIQUID venues (over a floor, default $5k): tight (trustworthy), arb_window, wide (likely mispricing), or single_venue (one pool, as manipulable as it is thin). Separates real arbitrage from thin-pool noise. Snapshots — confirm with a live quote. Not financial advice.
Output
Returns a spread classification (tight, arb_window, wide, or single_venue), per-venue prices and liquidity in USD, the computed spread percentage, and contextual signals indicating whether any gap reflects genuine arbitrage or thin-pool manipulation noise. This is a snapshot — not a live quote.
Example use cases
Arbitrage bot opportunity scan
“Is there currently a real arbitrage opportunity for the token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 across Base DEXes, or is the price gap just thin-pool noise? Use a $5k liquidity floor.”
Token manipulation red flag check
“I'm looking at investing in this Base token at address 0x4200000000000000000000000000000000000006 — can you check whether its price is consistent across liquid DEX venues or if the spread looks like a manipulation red flag?”
DeFi trading dashboard price health
“For my dashboard, pull the DEX price spread classification for token 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base so I can flag it as tight, an arb window, or wide mispricing.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/dex-spread?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess the price consistency of a Base token across multiple DEX venues, particularly to distinguish real arbitrage windows from thin-pool mirpricing or manipulation signals. Prefer it over a simple price lookup when spread analysis, venue comparison, or manipulation detection is the goal.
Side effects
- Invalid or non-Base token contract address returns an error
- Token with no DEX pools or liquidity below the floor returns single_venue or empty result
- Stale snapshot may not reflect real-time price movements
- Network or upstream DEX data provider outage returns 5xx error
- Malformed address format rejected with 4xx validation error
