CortexCloud Cross-Chain Token Comparison
x402
CortexCloud Cross-Chain Token Comparison is a paid API for AI agents from api.cortexcloud.org, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-30).
Compares a token contract's on-chain data (price, liquidity, activity) across multiple EVM chains simultaneously, returning evidence-backed JSON
Price / call$0.04

StatusUnknown
How this service works
Compare one contract across chains (price, activity, deployment) in one call (Alchemy + CoinGecko). x402-paid.
Output
A JSON object containing per-chain metrics for the given token contract — including price, liquidity, trading volume, and on-chain activity — enabling side-by-side comparison across up to five EVM chains. Payment is settled in USDC on Base via x402 at $0.04 per call.
Example use cases
DeFi arbitrage opportunity scouting
“Check contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 across Ethereum, Arbitrum, and Optimism and tell me where the price or liquidity differs the most — I'm looking for arbitrage opportunities.”
Token deployment chain selection
“I'm about to launch a new token and want to know where my target contract 0x6B175474E89094C44Da98b954EedeAC495271d0F is most active — compare it across Ethereum, Base, and Polygon so I can decide the best chain to deploy on.”
Risk research across multiple networks
“Pull cross-chain data for contract address 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum, Base, Arbitrum, and Polygon — I need to assess whether this token has suspicious concentration or low liquidity on any of these networks.”
Technical details
Endpoint
GEThttps://api.cortexcloud.org/v1/data/cross-chain-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare a single token contract's metrics simultaneously across multiple EVM chains in one call. It is preferable to making separate single-chain lookups when cross-chain comparison is the goal, and better than general block explorers when you need aggregated, evidence-backed JSON ready for agent consumption without managing API keys.
Side effects
- Invalid contract address format (must be 0x-prefixed 40-char hex) returns validation error
- Unsupported or misspelled chain names return an error for that chain entry
- Contract not deployed on a requested chain may return null or empty data for that chain
- Rate limiting or upstream data provider outages may cause partial or failed responses
- Response schema is documented as empty example — actual field structure may vary or be undocumented
