How this service works
Pay-per-call data for AI agents, paid in USDC on Base with x402: token risk checks (rug check) on Base, Ethereum, Arbitrum, Optimism, Polygon and Solana, onchain reads (balances, transactions, gas, contracts, NFTs, whale trades, new pools, ENS and Basenames), ECB exchange rates, and Canadian sales tax and business days.
Output
Returns a structured payload including: a list of individual large trades (each with USD value, buy or sell side, wallet address, and transaction hash), aggregate buy volume, aggregate sell volume, net flow (buy minus sell), and ranked lists of the wallets that bought or sold the most during the window.
Example use cases
Whale alert for DeFi token
“Pull the last 90 minutes of trades over $5000 for the Arbitrum token at 0x912CE59144191C1204E64559FE8253a0e49E6548 and tell me which wallets are accumulating the most and what the net buy/sell flow looks like.”
Pre-trade large-order sentiment check
“Before I buy into this token, can you check Uniswap v3 on Arbitrum One for address 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 — show me the top 20 trades in the last 30 minutes so I can see if whales are buying or dumping.”
Monitoring unusual sell pressure
“I need to watch for unusual sell pressure on the Arbitrum token 0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f — give me trades above $10000 from the last 2 hours with the biggest sellers and total sell volume.”
Technical details
Endpoint
GEThttps://ca-tax-api-mainnet.lxtap.workers.dev/arbitrum/trades?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, per-trade whale and large-trade intelligence for a specific ERC-20 token on Arbitrum One's Uniswap v3 pools, including wallet-level attribution and directional flow. Prefer it over generic blockchain explorers when you need aggregated buy/sell volume and top-trader rankings in a single call, without writing custom subgraph queries or maintaining your own RPC infrastructure.
Side effects
- Invalid or non-ERC-20 token address returns an error or empty result
- Token has no WETH/USDC Uniswap v3 pool on Arbitrum One — returns empty trades
- minutes parameter exceeds effective block cap (~50 min / 12,000 blocks) — silently capped
- minUsd set too high returns an empty trade list
- limit out of range (>40 or <1) rejected by schema validation
- Network or RPC timeouts causing upstream failures
